Title: Smoke on cold start-up with CRDI
Post by: terry hunter on May 01, 2009, 02:12:44
This topic was touched on in another thread but thought it needed one of its own as it can cause a bit of angst with new owners... like me!

Our CW CRDI is about 4 weeks old and running perfectly... with over 2000km on the clock.

Within the first week my wife noticed a puff of blue smoke when started cold. I mentioned this at our first free 1000km service at local dealer in central Vic. (not whom I bought the car from).

They said they couldn't find a problem.... and of course it is not evident once the car is warmed up.

Still a bit concerned, I booked in to see the service manager at a large Melb. dealer to talk about the issue.
He gave me over 1/2 hour of time explaining in detail why this might happen, and how the official input from Hyundai was that this is normal and not to be concerning at all.

He put the vehicle on the computer analyser and showed me all the systems which are checked... including the diesel particulate check, and that everything was normal.

Wow, there are over a hundred different components that are checked via computer just in the engine system... and there are eight different systems in the I30 that get checked!  This was good PR if nothing else.

He explained that on cold start-up, the sensors measure the air temp and engine temp and inject 4 lots of fuel into the cylinders at varying amounts within the 4 strokes of the motor to lubricate and prime.
The smoke on start-up is a result of all this 'extra' fuel/oil and of course disappears after start-up.

He said some times you will get more smoke than others and this is exclusively due to the varying qualities of diesel fuel available.
He said all Australian diesel fuel is cr@p compared to Europe and varies greatly from supplier to supplier.

Though he would not name any ones to avoid, he said I should try four different suppliers and compare both the power and smoke variations that I will no doubt find. He said power differences are very noticeable!

Even though Aust. now has lower sulphur content in diesel, apparently there are many other factors that determine how good and how clean diesel is.

He went on to tell me all sorts of other things ( he has been to Hyundai in Korea) as is thoroughly impressed by the company... particularly this new breed of diesel which is state of the art.... Italian designed, Bosch Electronic injection, and Hyundai manufactured.

Problems with them are rare indeed and they continue to impress all motoring critics and writers with their frugal fuel use and efficiency.

All in all I was impressed with the time given to assure me that all was well... and that the I30CRDI is a brilliant piece of engineering... and that Toyota is definitely looking over its shoulder!

From my readings, there are currently only two car companies that are making money... Hyundai and Audi. (not sure where Ferarri is in this as they never seem to be affected by economic downturns!)

Hope this is helpful to others.

T.H.

It shouldnt be blue smoke.  Extra fuel will result in black smoke.  I've never noticed any smoke come from mine, but there is a small black sooty mark on the carport floor where I park.  If its blue smoke its either oil leaking in down the valve stem seals, from the EGR, or low compression / timing issues (normally whiteish smoke more than blue).  Didnt camerooney have blue smoke issues on startup too?  I'll have a search.

Here 'tis.  I guess he never found the resolution to it before selling.

terry hunter,

Is it so smokey that you can see when you are sat in the drivers seat?

Otherwise I'm as shambles on this and so long as it doesn't smoke like my son's VW diesel, like an old steam engine, I'm happy

Hi, I too recently got myself a i30CW CRDI and have done about 1500 km on it. No blue smoke thus far...a bit of white smoke early in the mornings when its cold.

Post by: Lakes on May 02, 2009, 22:52:36
Just read this post, blue smoke = engine oil, black smoke = rich diesel ( or more diesel being injected for cold start ).
there was a wise saying once. if you can't impress them with briliance, baffle them with ..... . it is easy to plug in to a PC and show all the readings from all the sensors. but only way to check or fix a leaking valve stem seal, is to remove the cylinder head.
over head cam need a lot of oil up the top end to lubricate cams and so on. when you turn motor off there will be a lot of oil up there around the valves stems, if a stem is not sealing the oil leaks into the combussion chamber, then when you first start it burns , and makes blue smoke, mostly only see it at start up after car has been standing, if it's bad they do it every time you restart.
we have Caltex Vortex Premium Diesel and BP ultimate premium diesel. i'm in Sydney and buy Caltex Vortex Premium diesel just cost's more, but motor runs noticibly smoother with slightly more responce.

G'day eye30,

On cold start you can just see the smoke puff from the drivers seat and it's hard to say if it's white or blueish white.

Will try another diesel supplier after this tank full and keep an eye on it.

We have a volvo wich has over 200.000 km. It has never had smoke behind the car.
My car from work also hasn't have smoke. (both diesel)

I can say that the fuel here in belgium has great quality. Thats why many people here chiptune their car to optimize the car for our fuel.
Some people have 30hp more and have less consumption! All cars have a standard program in their computer so they can drive everywhere on the world.

Hi all

a little info from me...  i was learnt that when the smoke from the exhaust is :

black = unused/ unburned fuel  / misture screwed or tampered with.

Blue = it using lots of oil... 

while smoke :  condense water from exhaust or coolant .

i would keep a good eye on ya oil level the next few time u r filling up with diesel..

when that said : its pretty normal that new cars uses oil.... till they r like 15000-25000km

the reason : all the engine parts have to get set in.... short version..

also the reason why u r not allowed to tow heavy loads and such when the car is new... and rev it heavily...

cheers all

Terry,
there must be a way to analize, the exhast.
Also if our diesel was not up to Euro standards, the big euro manurfacturers would not export there diesel models out here.
a few years back a friend of mine in USA said they could not get the top line euro diesels there as they did not use low sulphir diesel, he also noted that we could get the latest euro diesel models here. since then USA have also moved to low sulphir fuel.
you can have fuel tested yourself & see if it matches up.
but Blue smoke on start up is oil, and if it does not keep blowing blue smoke while runing, it is most likely coming down your valve stem's, meaning the valve stem seals are not sealing, these seals do not need to wear in they should seal, it won't go away with time.
Good Luck.

I've booked the car in for another technician opinion to local Hyundai centre.

They kept it overnight and this morning, they told me that the glow-plug is not working. The colder it gets, the harder it will be to start.

Will be interested to see if this is connected to the blue smoke or not. I can't see the connection but at least it's one less problem down the track.

I'll keep you in touch with progress.

The car has 1 glow plug per cylinder urs got 4 of em :P

normally when a glowplug dies... the glowplug symbol either is on all the time or dont light up when u wanna start the car.

Terry, the i30 CRDi do not use glow plugs, Lucifer pointed this out to me. i don't think any of the diesels for the past??? say 10 years have used them. they have a heater that heats intake.
the Trucks at work i drive sometimes are much faster to heat up than my i30, they have the heat up light go off almost instanly.
Terry is it very cold in mornings were you are?
as fuel companys change diesel blend summer to winter. i use Chem Tech Diesel Power it's a fuel conditioner helps cold start too. but not realy cold here in Sydney yet.
Title: Re: Smoke on cold start-up with CRDI
Post by: LuciferDarklord on May 10, 2009, 10:22:39
I was kinda guessing they didnt have glow plugs, based on the fact most Direct Injections diesels have a high enough compression ratio and small surface area to lose heat.  They shouldnt really need a glow plug to start at all.  My guess was that the pre-heat is a coil or element in the intake manifold that heats the air, and is purely for emissions and to help reduce the diesel rattle when cold.  When I took my engine cover off a few weeks ago I forgot to look for glowplugs, but when Lakes had a look he couldnt see any.  My wife has forgot to 'glow' a few times when starting, no smoke, no hunting or missing.  Generally with a pre-combustion diesel that needs glow plugs, if one is buggered it blows a very light blue to white smoke (normally white) and run rough and sometimes missfire on the cylinder(s) with broken glowplugs.

Sorry to be slow to get back on this smokey issue, but have not yeat had the replacement "glow plug" (heater) replaced as yet. It is still coming.

The service guy told me the technician was very confident this was the smoke problem. We'll see.

Temperatures have not got below 5 deg. here in central Vic yet this Autumn but we can have a run of -3 to -5 mornings during winter...and the vehicle has not been hard to start so far. It takes about 2 seconds for the "glow" light to go off and it starts within 2 secs. of turnover. So I'm not sure why he thinks it's the glow plug issue that's causing anything.

But then again I'm pretty ignorant on these things.

I'll give more feed-back when I know more but thanks for your input all.
It's due to you that I've kept chasing this up even after being told all is well by those who have not actually seen this issue!

Title: Re: Smoke on cold start-up with CRDI
Post by: terry hunter on May 21, 2009, 01:19:06
Well the service chap has replaced a special fuse which controls the glow plug sensor and therefore cold start fuel management.
This was blown from something earthing out and needed a spacer.

He was very confident this was causing the blue smoke on start-up when cold. Anyway we'll see once the weather gets cold as is currently not getting below 7-8deg.C overnight.

I asked him why the smoke was blue rather than black... to which he replied (my summary as I understood him) that black smoke is a burnt fuel particulate issue... whereas the blue smoke was unburnt extra fuel from the poor management at cold start due to the blown fuse causing poor controlling management.
He said diesel fuel can be either black or blue coming from the exhaust and is unlikely to be excess oil in the cylinders.

I'll keep all informed as to the accuracy of this as others may have the same issue.

Terry Hunter

... By the way, he said it does have glow plugs rather than a heater... and no CPF which is expensive and will be on the new 4WD.

Well there was no blue smoke this morning... though it wasn't very cold either.

Have to wait till deeper into winter to really test it I suppose but so far so good.

If the issue is solved, then blue smoke can be caused by other factors than oil seeping past the valve stem seals. This must be good news to those who feared this... and certainly to me.

I'll keep in touch.

Terry, I've watched this thread with interest.  It might depend on one's perception of blue but I've never seen any blue smoke that wasn't burnt oil (not that I'm an expert :-[).

Lubricating oil can of course get into the combustion chamber via the rings as well and I would expect some to do that even if the consumption is near zero (else how is it lubricating the upper cylinder?).

Maybe the answer is related to the normal combustion (which might burn the small amount of lubricating oil to invisibility) not happening at startup if the glow-plugs are not powered.  My understanding of glow-plugs from RC days is that they remain hot enough to give a hot-spot "starter" for ignition once the engine is started but need pre-heating (with battery current only applied until engine fires) to give a similar effect from cold.

The other thought is that diesel is close to oil on the petroleum scale and maybe given the right temperature will burn blue??

Yeh hi Pip,

I tried really hard to talk myself into thinking the smoke was anything but blue as I didn't want the hassle of chasing up warranties, car out of action, always wondering if we've got a lemon and all that.

But I have persisted with the issue and hopefully this young technician at local Hyundai has put his finger on it as this is my third attempt to have it acknowledged and responded to. Not that the other attempts were ignored but they were not diagnosed as the car had to be left overnight for them to start-up from cold to see.

So I've not seen any smoke at all for the past two mornings (though warm mornings) but I'll keep a close eye till well into winter.

Terry H
Title: Re: Smoke on cold start-up with CRDI
Post by: terry hunter on May 30, 2009, 12:56:48
I' happy to say that there has been no hint of the blue smoke issue since the young techi did his thing with the fuse replacement for the glow plug.

We've had some frosty nights lately and not smoke at all on startup.

So I consider the problem solved and thank all forum inputers for helping me to persist till it was solved.

It got a good workout too with my recent supplies trip towing and carrying over 1 tonne of stock in the trailer and wagon below... and it towed suberbly!... with no need even for gear changes (out of fouth) up several steep hills between Bendigo & Melbourne.
Mind you it does chew through the juice if I keep it at 110km all the way... but much better at 90-100km.

A top little performer workhorse the CRDi.... and hope to get 1/2 a million kms from it during the next 10 years... :mrgreen:

I've attached some shots of the trailer (hope they come out...) and genuine i30 towbar which I'm impressed with as far as ease and neatness but the rattling was driving me crazy till I wrapped the stem in some tape.

That's pretty standard when you give it a heap of welly - the computer is just fuelling the motor up hard. Given a CRD (even a stoopid Astra) will pull up to 5000rpm, which is quite a bit different to the older diesels, you are less likely to get thick clouds of black smoke as the engine lugs under load.

Also, automatic Astra diesels (which is most of them) have a DPF, which would substantially reduce the amount of black soot coming out the back.

DPFs also have a regeneration phase, in which they actually burn off the particulates that they have captured. Depending on the circumstances that can make a little bit of smoke.

The regeneration phase can be triggered by full throttle, so that's a possibility.

At the end of the day, even though Common Rails have a lot of technology and have been refined, diesel is a less refined fuel and will be more prone to smoking.

For the record, we used to receive vehicles off the trucks from the distributors making blue smoke. It's not the end of the world, especially if it goes away when it's warmed up a little. Glad to hear Terry's car came good with what the dealer did.

Ref. the tow bar issue, Hyundai don't actually design their cars to tow extensively, and really I wouldn't tow much more than a small trailer with the i30. You're unlikely to have a serious problem, but it's not going to do the body (or the drivetrain) a lot of good.

For the sake of your warranty, I would not use anything other than a genuine Hyundai bar. I believe that Hayman Reese actually may make the genuine bar for Hyundai, and Hayman Reese make great products, but just be aware that if you fit a non-genuine accessory to your car and it can possibly seem that it caused a problem then you will lose your warranty. Even if it seems unreasonable, this is the risk you run. Towing is a real issue for manufacturers and I have seen major failures caused, and warranties voided, by the use of non-genuine equipment or the overloading of genuine equipment. Given that the i30 is a passenger car and doesn't have a chassis as such, towing puts a stress on it that it wasn't really designed for. It's a good idea to make it as easy for the car as possible. Having said that, I have seen footage of Getzes being used regularly to tow caravans in the UK.

Suffice to say I wouldn't buy one of those second-hand!  :eek:

Just my two cents. Sorry it's such a big post, this is (believe it or not) the first time I've looked at this thread.  :wink:

Thanks MRH130, good post, i think i'll keep my falcon Ute for towing as it does not seem to notice towing and fuel economy does not change much at all 10 to 14L 100K

Thanks Lakes, and if your ute is a BA (which I seem to remember you saying somewhere) it has a half chassis so it's going to be plenty strong enough, and towing, as you have noticed, isn't really going to worry the drivetrain very much.   :wink:

Hello,

I think (hope) I have the same issue as written few posts ago.

Today, when I started the car blue smoke "came out" of the exhaust. It happened right after starting the car (which btw didn't start easily - it felt like it will "die" but it managed to work on). After 2 seconds there was no smoke coming out.. The temp is/was around 0°C.

I've also noticed that lately (especially when the temps were around -5, -10 or -15°C) it doesn't start as nice as before or as in warmer days. Sometimes it sounds like it will turn off or shakes a bit,..

So..I'll call my dealer tomorrow probably, but just wanted to ask for your opinion before doing that? The car is 1 year and 1 month old and has around 55.000 kms.. It would be weird if the glow plugs were the issue at those km's but I sure hope they are  :)
Oh..and could it be due to bad fuel? I had to stop on our biggest and almost only fuel distributors (we only have 2 or 3 in Slovenia) last day and which is known as not really great one (had some quality issues).

Thanky, have a nice day/night and..happy New Year  :wink:

Hi accim

Just a thought, when you start the car do you wait the 2-3 seconds for the glow warming light to go out on the dashboard before cranking the engine? But may be bad fuel.

Wouldn't huirt to change fuel supplier anyway, maybe it has poor cold weather/waxing problem.

Yap, I wait till the light goes off (these days it takes about 3 seconds). I went to other (my usual) gas station today and we'll see tomorrow. And yes also..today I had no problems - no smoke on start (so far), neither did the engine sound/run strange.

Hubby started the i30 up the other morning and said there was heaps of BLUE smoke  :eek:  It didn't happen again over the next few days.  I've booked the car in for its 12 month/15,000km service and mentioned the smoke.  The girl who took my service booking said to keep an eye on it.  How I'm supposed to do that when the car isn't being driven and we aren't there, I don't know.  Will see what happens when we go back to Perth next week and start the car up.

I think i30mania was suggesting to check the glow plug fuse in the engine compartment.  Could be a possible cause of smoke on startup.

Sorry to butt in when I haven't been here for so long... but my blue smoke on startup... as mentioned earlier in my post - and with my new car, was caused by the blown glowplug (fuse?) which was in turn caused by some shield touching where it shouldn't and shorted it out.
The shield was adjusted, the glow plug (fuse?) replaced and no smoke from then on.

One service centre picked it up... the other did not and tried to convince me that all diesels do this and it's normal... or I had a bad fuel supplier.

In diesels, even a very modern common rail unit, a blue smoke should be very alarming.

Normally diesels should not exhibit blue smoke even with worn out valve stem seals that are the normal reason for blue smoke on petrol engines.
A diesel would just burn the engine oil just like the diesel fuel.

Did you know that a diesel that leaks engine oil into combustion chamber can even self destruct by runaway rpm's?

Good job that's not what the issue is then.

The smoke on startup isn't alarming, it seems pretty normal on an i30 if you don't allow the glowplugs to work, either through faulty fuse or over-eager starting.

It took me two i30s to figure it out. On my first i30 I noticed smoke coming out during a morning startup on a few occasions, and not all the time. I couldn't figure this one out, even after reading posts like these. I was resigned to the possibility that it might be premature wear and tear. So when I sold the first car and got the second i30 I noticed it happened again just after my first service. Then it clicked. I almost always got in the car and started her up straight away (and without even thinking about it), without waiting for the glow plug to complete its 3 second cycle. From then on I wait for the glow plug light to disappear before starting and no smoke has appeared since. As simple as that. I extrapolated that the colder it gets in the morning the more important it is to rely on the glowplug to heat the fuel. Just passing on some knowledge based on my experience of owning 2 i30s.

Hi all, been reading all the posts on this topic with interest, very lengthy thread!

Had my new CRDi for just two weeks now and noticed after the first few days there is a cloud of 'White' smoke on cold start up. It is interesting to read so many people are mentioning blue or black smoke but mine definitely is a 'White' smoke which, I am told, indicates unburnt diesel. I have booked the car to looked at next Tuesday as the dealer wants it overnight so they can do a cold start and analyse it from there. I'll let you know what the findings are because clearly this is a bit of an issue for some diesel owners.
Couldn't be happier with the my i30 I have to say, just like to resolve the smoke issue if possible, doesn't look good when you have a great new car and you drive away in a cloud of 'white smoke...' :)

Yeah, doesn't sound quite right, I only get a small bluish puff for a second or two if I start up, and only when it's a) cold and b) I forget to wait 2 seconds for the glow plugs to warm up before ignition.

Thanks all for your comments.

Had the problem checked out today and the diagnosis is we have a faulty Glowplug relay which will have to be replaced. So, no major drama!
Won't get the part until Friday they said, meaning it will have to wait until next week to get fitted which should only take about half an hour. The car runs really well so I am not concerned and will let you know if anything more comes of it. :cool:

Cheers

Gday all.

Our CRDI has an intermittent problem of rough idle and blue smoke on cold start (ie the 1st start of the day) . We always wait a few seconds before starting . Just dropped into the dealer who found no error codes and checked fuses OK.
Wondering if anyone else has the rough idle symptom along with the blue smoke on cold start ?
Also wondering if it is possibly an electrical problem (an intermittent short ?)

Any comments/feedback appreciated.

Cheers
Dave

My wifes i30 is starting to do the same, sometimes the blue start up smoke is that bad, it's embarassing! Have checked fuses, just filled up from different servo, see how that go's. Got 45k service shortly, will speak to service department, no other problems, just the smoke issue.
I'm hoping its just a glow pug issue & nothing sinister!

My problem with this has reared it's ugly head again.   :mad:
Seemed to ok for a while after the dealer replaced the Glow Plug fuse but noticed, particularly today as I had to move the car a few times in the drive way the cold start smoke back to where I was. :'(

My dealer is in Coffs Harbour which a bit over an hour away and a pain to organise especially if they want it overnight again like last time. Thought I might talk to the local Tyrepower garage as they have a pretty god reputation and see if they are able to do warranty work. Be a hell of a lot easier at this point.

Ok, Smokey is smokeless again!  :cool:

The mechanics at the dealer found the glow plug fuse to have failed again, as I had suspected. The cause appeared to be that the glow plug had been able to short against the cylinder head, they have adjusted this so with a bit of luck there will be no recurrence. Unfortunately I was unable to speak to the mechanic directly as I would liked to have had more specific information to pass on but after testing it out with several starts this morning I can say all is well!  :wink:

Hi Terry - think your car is the brother of mine car KT.

Sorry to sound like a broken record, but I had black smoke coming out of my exhaust when starting the car up.  Does it happen when you're driving and put your foot down?  It did for me - I had this symptom.  Eventual diagnosis of the route cause (fuel economy dropped, eventually lost power when using the accelerator) - uneven wearing of the drive plate.  Resulted in replacement drive plate and new clutch.  Apparently according to Hyundai Technical, there is a known fault with uneven wearing on some drive plates, hence finding the fault with a detailed search.  They say the wearing on the drive plate may have contributed to the black smoke.  Just a thought if you start running out of options...
Title: Re: Re: Smoke on cold start-up with CRDI
Post by: Lorian on November 21, 2010, 08:35:15
Uneven drive plate wear is not something seen as a common problem here. I don't actually recall anyone reporting it.

Avoiding Smoke on startup needs the driver to understand they have to wait for the gloplugs to do their work and if the problem persists the dealer needs to check the plugs, fuse and relay.
