Ho hum, had four new tyres fitted 10 days ago and all was well. Yesterday whilst driving the ole Low pressure warning light came on with the indicator for the NSF tyre. Pumped it up and headed back to tyre bay today, thinking had a puncture. Nope, the rubbers on the TPMS valve had perished! Got a standard valve as a temporary until I pick up the new one. :evil:
New valve on order, but will see what dealer says about the old one.
-
Just had mine replaced, dealer checked with hyundai uk and they are covered by 5yr warranty, mine snapped on the thred, dealer said it must have been 'corrosion' :wink: took about 40mins to replace and program.
-
Well I hope my valves last longer than you guys, and longer than 5 years too :eek:
Would be nice to know what an out-of-warranty replacement set would cost, and whether it's possible to disable the TPMS radio reception (in cases where the cost of replacing outweighs the benefit of the system itself).

Obvioulsy dealer will likely be more, looks like about half that to import (google schrader airaware)
Cheap(er!) import

Implies kit should be used when tyres replaced on rim.

Lorian, you beat me to it with your link.
Have also found this,
http://www.dmtyresupplies.co.uk/catalog/product_info.php?manufacturers_id=12&products_id=230
These sensors are used for various cars does not specify i30 but I bet if you had the details they could get it at this price.

£69.33 for one valve :eek:
-
Shambles you were quick with that reply. I was modding my post.
I bet Hyundai price is about £120.
-
I added an ebay auction to my post above - much better value, about £30 delivered to the UK from the USA.
-
Well I had good news and bad news re my replacement valve today, bad news the sealing rubber for the locking nut hadn't turned up, but should be in tomorrow. Good news, Hyundai are paying for it under warranty, so saved me £55 odd plus VAT.

just had two new tyres on the front and during the process the tyre fitter snapped off one of the valve stems

I discussed this with him and agreed that the threaded portion of the alloy stem seemed corroded. The point where it snapped was where the valve cap ends, presumably a good area for corrosion. Having a chat with the manager and the fitter they suggested that this was a common problem with these sensor valves, not just hyundai. I'm going to ask my local dealer that this should be replaced under warranty as it is a manufacturing defect, ie the part was not designed correctly and was likely to fail. I'll let you know how I get on.
It does occur to me that these weakened by corroded components could fail at an inconvenient time, eg whilst travelling at speed.
-
Useful info JP. Thanks.
Still, better than a Fiesta with no TPMS eh? (just trying to make you feel better)
For sure, I'd pursue this under warranty; keep us informed please
-
Presumably it had a metal valve cap? Best to keep the plastic ones with TPMS.
-
There's a standard procedure for removal and refitting of tyres on wheels with pressure sensor valves.
Doesn't matter how corroded the valve stem may be, if it's done properly there'll be no contact between the tyre bead and the valve, so it won't break off.

nope, silver plastic one. I was thinking crevice corrosion as opposed to galvanic

I imagine my generally competent tyre fitter has come across these before. I'm told that the stem snapped whilst the valve insert was being removed, a fairly benign operation. I don't see why these valves are made with corrodible, ie aluminium alloy threaded stems and so therefore more susceptible to damage. Standard stems are made of sturdier stuff, presumably because failure and subsequent deflation could be catastrophic. This valve is 2 years old, and doesn't inspire me with any confidence in the longevity of the remaining three valves.
-
I know it doesn't help you, but it's a good warning to the rest of us to keep these threads clean and sealed from the elements, thanks.
It will be interesting to see what Hy say.
-
the stock valve stems are made from brass with a rubber outside wall that pulls through the rim when fitted. :wink:
-
All OK now.
took the car to local Hyundai dealer for a service 3 weeks ago, showed them the valve and asked that it be replaced under warranty. They took the valve and said they would 'send it to Hyundai'. This morning I took the car in and the valve was replaced. The new one looks like the old one.
I don't know if it's a general problem or that they decided to do it under warranty as the easiest course. I think I'll be especially careful on the next tyre change.
I would have liked to have discussed the problem with someone, say a mechanic, but garages being what they are nowadays one can't get past the 'reception' staff. I have in the past asked the reception staff if I could speak to the mechanics but as the reception are mostly young ladies and I have passed the age (I think it was 45) when young ladies take any notice of what I say or are inclined to do me any favours it was fruitless.Thank goodness my local bike mechanic is not like that, I can just wonder down there and talk to a bloke in overalls amid the oily chaos.
-
Nice one jp. The threads are very fragile so I am very careful when checking pressures.
-
I had one of these break on me, exactly the same as in the pictures above. Got mine booked in, was told it would cost £120 odd. I reluctantly agreed as it needed doing, when it came to paying, a guy walked past just as I was about to pay and told me to turn around and walk away. In the time from me breaking it, Hyundai had apparently decided that the tyre valves were covered by the warranty :D
Walked out of that dealership with the biggest grin on my face.

Nice result - congrats.. :mrgreen:

A TPMS warning light came on this time on one of the rear tyres - (see my other post).
https://i30ownersclub.com/forum/index.php/topic,6351.0.html
I initially tried to add air using a mini tyre inflator but it made no headway. I checked to see if it was connected to the tyre correctly and could feel air from around the valve. This suggested that the connector on the mini inflator was not connecting properly as no air was entering the tyre. I therefore took the car to an air line at the garage and bingo - the valve broke off when I attached the air line meaning I had to replace the wheel.
The car has only done 10K miles and is due its first service at the end of September. I'll take it into a dealer tomorrow (not the one I bought it from which is in another town). Will be interesting to see if I get the valve replaced under warranty as they seem to very costly.
I've tried to post up a couple of pictures. Members might be able to advise if this looks like corrosion. I'd read about valves snapping on the thread and was really careful when I attached the air line at the garage.

Looks a bit corroded to me :cool:
-
Did you have the original plastic valve cap on it?
This is an cautionary article on these aluminium stems with gas station air supplies:
http://techinfo.honda.com/Rjanisis/pubs/SN/B090700.PDF
Of course, its still not fit for the purpose, so you'll be expecting them to replace it under warranty....
-
Yes - just the plastic cap that came with the tyre. I looked at the link and the air hose was the preferred type described in the article (went to the air pump at Tesco).
cheers

I think you stand a pretty good chance of getting a warranty replacement then.
I just took the silver plastic caps off mine to clean the threads. Actually the caps are black plastic sprayed sliver.
Anyway, and this will of course seem obvious, but the threads on mine are dirty but not really corroded yet but the thread under the cap is like new. So what they need to do is spend an extra penny in manufacture and specify longer caps.
-
Thanks Lorian. I might try and buy a set of longer caps. I was thinking about how I could protect the exposed thread and had thought about adding a smearing of grease. Longer caps are a better idea!
When the car goes for its first service in September I'll ask the garage to check the condition of the other valves as this valve failure doesn't inspire me with confidence.

Another thought - What do you clean you wheels with - anything acidic?
-
Autoglym Clean Wheels which is left on for a minute, worked in and sprayed off.
http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_196195_langId_-1_categoryId_165682#dtab
Checked the ingredients and it says it contains phosphoric acid. A chemical reaction perhaps?
-
Valve replaced under warranty. Interestingly, when I went to have the valve replaced the garage advised that they since I originally reported the fault they had replaced valves on another three cars where the cause had been corrosion. A cheap fix to the problem presumably would be to fix a full-length dust cap covering all of the valve stem. I don't know if such a thing exists however as I've not been able to find anything l online.

I've never had a TPMS system fitted to any of my many cars.. It looks like this Toyota system might not use valve sensors (I think it is about A$300) I will have to investigate it further as the problems you guys are having with valve failures it might be a better alternative... :cool:

-
One thing to note about the supplied silver plastic caps is they have rubber o-rings installed at the end to make a seal, and most after markey caps you can buy dont have this. I have a little vasline on my threads to try to keep them in good knick.
-
A dab of vaseline sounds like a good idea Lorian. I think the TPMS system is a good feature if only the valve stems were more robust. I'm sure I read somewhere that all new cars in the EU will need to have a TPMS system fitted from 2012.
I also noticed when I got the car back that the HALO system was been activated. It hadn't worked before and I didn't realise it was a feature of the car until I consulted the manual after noticing that the door was locking and unlocking automatically.. I'm guessing the garage would have done this when they were re-setting the TPMS.

There is mixed feedback on the Halo locking system.. I never got mine activated but I reckon it would be pretty cool (auto lock and unlock..) :razz:
-
Re the HALO, I've developed this party trick when I have new people in the car.
Start off, accellerate up towards 40 kph and just before I get there I take my left hand off the wheel and snap my fingers.
Presto. The doors lock. :lol: :cool:
