It started about 10 weeks ago with the occasional throttle cut, which is easily remedied by taking my foot off the throttle and reapplying. This happened at first once every few days, but has now become once per km!! However, that's not all. In the last few weeks, the CC will suddenly drop off and not allow me to reapply it until the car has been switched off and restarted. The ESP OFF light will now come on on nearly every journey, (I did have this problem before but was resolved by my local Hyundai Dealer in Geraldton when they replaced some brake assembly switch, but hasn't come back until these latest troubles started to get worse). And the newest dimension to this most vexing issue is sometimes when I get out of my car the brake lights are locked on and can't be switched off without starting the car, applying the brakes and turning off before any of the other aforementioned gremlins hit.
My i30 has nearly 100,000km on the clock, and the only major drama I had recently with her was due to having used too much Biodiesel and had some kind of fuel bug that had blocked up my filter with black sludge (which my dealer had no idea what it was as they had never seen it before!!) but a fuel filter change resolved that problem about 5000km ago, which was causing complete cut outs of the engine or the occasional entry into limp home mode.
Living in Geraldton in Western Australia (having emigrated from Blighty 4 years ago) means I'm about 450km from any serious Hyundai Main Dealer, and with so little [no] competition, you can imagine what it costs here, but it is in the order of $150ph for investigations. Hence I am going to see if I can, with your help, get to the bottom of it myself.
Any insights anyone might have would be greatly welcomed.

Not good mate! (I am a master of the understatement)
I am no mechanical expert, the brake light switch and or dirty fuel or a combination of both would be my main suspects. It would have been your brake light switch that was replaced under warranty, but they could have either fitted the wrong one or the replacement could have failed. A fuel bug usually takes more than a filter change to fix (the tank should be drained and cleaned and an anti fungal additive added to be on the safe side. Hopefully others can help.. :fingers:

Hope this helps.
I suspect your brake switch need further attention, too.

Is changing the brake light switch a possible job for home?

Given your location, I would be careful about where you obtain your Diesel from. Do not use garages with low turnover of fuel, as their tanks may be the source of contamination. If you see semis filling, I would also fill there as well. The Diesel bug is an airborne fungus and seems prevalent in Australia, compared to other countries. The northern Oz territories can be quite warm and humid, ideal for this sort of stuff to grow. The fungus grows and survives only in the layer where water and oil meet, so by eliminating the water from the tank, the fungus can not survive.
I have no affiliation with the supply company. The product is expensive but 1lt treats 4000 lts of Diesel. A tank clean by Hy is around $300 I believe.
Condensation can form in your tank as it empties. The fuel when full is eventually replaced by air from outside until the next fill, so this treatment should eliminate contamination issues.

I was using Biodiesel for a couple of years and suspect that was the source of the infection. I have just order a Fuel Biocide and we shall see if that helps at all. My 2010 CRDi did come with factory fitted CC, so I shall watch out for that, and it does lend some weight to that as the problem as they are all interconnected; ESP OFF light problem, CC disabling, brake lights etc. I was thinking that maybe there was a loose cable somewhere or even a faulty throttle position sensor??

Hyundai Australia issued a confidential bulletin to dealers in June warning of a problem with the brake light switch assembly on all passenger and commercial vehicles made between August 2011 and May 2012 - during which time the company sold more than 70,000 vehicles.
It listed the following conditions: “stop lamps inoperative upon brake pedal application, cruise control inoperative/drops out, engine starting not possible [some models], unable to shift transmission lever from or into “park”, ESP light staying on."

Just spoke to my dealer and apparently it went back as far as 2008, and they are changing the switch for free on Wednesday!!! :Shocked:

Get that done and all will be good.
Remember to test your cruise afterwards before going too far. Just to be sure they fitted the correct brake light switch.
On a side note I agree with all about the diesel bug. There will still be contamination but I don't think that's your problem now.

Hopefully this sorts the problems out, but keep away from bio-diesel.
I have only ever used it a couple of times when the option was use it or walk 100 kms, but I stick with BP or Caltex premium fuels.
100,000 kms on one of these diesels is bugger all so hopefully you can sort this out and continue to enjoy the car. :)

Indeed I agree, I never thought I'd get such great responses so quickly, so a big thank you to all and fingers crossed. I did read up about making sure the correct replacement goes in, and I shall remind them on Wednesday :wink:

This is not to take away from the advice given re fuel, but since the accelerator is also electrically driven and would be in tandem with the brake system under the overall electronics it just seems to be too much of a coincidence.

I think suspects correctly that his i30 is possessed.
In which case we can make a new badge for the boot - CRPi.

Try to apply the brake at the same time as keeping a steady speed, and you will see the power disappear. :mrgreen:

So it's early days, but it would appear that the problems have all disappeared
Try to apply the brake at the same time as keeping a steady speed, and you will see the power disappear.
This was the nailer for the Brake switch for me, I wasn't aware of this until I tried it driving to the dealer. So about 50% of the time I touched the brake it would drop the revs and return when I removed, but the other half of the time it would cut the throttle completely and I would have to lift off and reapply. My wife driving behind me, said that each time it had the fail state, my brake lights would remain on after I removed any brake pedal pressure. So I was pretty much convinced by that point that the I needed to changed my vote from demonic possession

I had the diesel bug once and that was how I dealt with it, now I use at all times a fuel additive that deals with the pest

The Limp Home mode can also be caused by Overboost.
Is there any faultcodes?
The brake light switch is it changed? If it`s changed is it changed to the modifyed switch? That have and extra ground wire?
Correct me if I am wrong but Hyundai only allow up to 5% biodiesel according to EN 14214

Also thought I should add a photo of my i30 for my posts, taken last night in the depths of WA darkness!! And no there has been no doctoring, the Milky Way really is that clear up here
