Title: Broken down - turbo issues?
Post by: phil_790 on 31 March 2015, 20:16
Hi all,

Had a bit of a nightmare tonight, was driving along at about 40 coming off a roundabout lost a good chunk of power, then the EPC light came on, followed by an orange engine light. Pulled over and then I had a start/stop error and a whole range of lights on, car then ran very lumpy.

Stopped the car, VW assist/AA came out, took it to the dealers, he had to start it up to get it off the trailer, when it produced a pretty large amount of blue smoke after which the engine was running ok.

Frustrated to say the least, waiting to hear back if there is a hire car available at Gatwick airport.

My initial guess is either turbo, or coil packs. The car is totally untouched in terms of tuning boxes or any other mods.

Cheers,
Phil

Frustrating for you  :angry: but thankfully Volkswagens problem now  :laugh:
Hope you get it sorted quickly.

To be fair, vw assist have been pretty good, car taken straight to dealers and rental car arranged, Volvo v40 diesel auto, interesting drive.

Just hope it gets sorted soon!

Had a split new v40 diesel auto from Europcar Gatwick a few weeks ago. Not a bad car but not a patch on the Golf IMO. Took me a while to get used to having a physical handbrake again lol

The manual hndbrake wasn't too bad, as I sometimes drive my other halves mini. Automatic was weird at first, but after a 15mile drive home it was quite nice. Off to the dealers in the morning to see what's going on with my gti.

Plume of blue smoke on restart? Sounds like turbo failure with some oil getting burnt in the process. New turbo, new plugs, possible new cat if the oil combustion has poisoned it.

Apparently when the car was taken into the workshop and wasn't showing any warning lights, no word on what the problem is yet, so I am still using the V40 until tomorrow, VW want to get me into one of their own courtesy cars.

Will have to wait and see what they say tomorrow.

Hi,

The car has been in the garage for almost a week, they recorded 7 different error messages from the incident, but they don't all point to the same source. They started it up Wednesday and found it be running lumpy, however they have run it again today and reckon it's ok. The possible explanation they have is some dodgy fuel getting through which screwed up the timing and let the oil get through to exhaust where it ignited and caused the blue smoke. They are going to run the car again tomorrow and see how it is.

To be honest I am not 100% convinced of the fuel explanation, but we shall see.

Either way I really don't like the golf SV they have given me, however it has given me the chance to drive a DSG which is interesting.

Any thoughts about the fuel explanation, I have always been a bit picky with fuel and only use shell or bp.

Cheers,
Phil

Not sure how dodgy fuel could cause oil to leak into the exhaust...

I was under the impression it might be due to the timing being off, but I don't really know a massive amount about cars!! The thing I find really odd is that the car seems to be ok now, don't really want it back until the dealers are happy it's all good.

It's the little fob-offs like this that worry me about keeping a VW (or any other car) beyond warranty. Something went quite wrong and they can't be bothered to fix it if they think it might not happen again in the immediate forseeable.

At least the guy on the service desk did say that they are frustrated that they cannot recreate it. I have made it pretty clear that I don't want the car back until they are 100% confident its all good, but I can see where they are coming from in terms of it not being repeatable.

I have always been a bit cynical about the comments they supply. For example a couple of weeks ago, I had new front tyres fitted at a national chain of tyre places, whilst there I got the tracking done, it wasn't until I got home and read the report that I noticed that they set the parameters up for a Golf Mk6 and not a Mk7, their reaction was "oh well, they are both VW Golfs, how different can they be" As it turns out they were quite a bit different.

Not really having much luck with the car lately, first the scratched alloy when they changed the tyre, then the wrong alignment parameters and now the issues from last week!! To be fair though the alignment and scratch were nothing to do with VW.

Ahh the good old dodgy fuel scenario, now where have I heard that before....

Dodgy fuel claim - can you produce receipts that show you've only ever filled up with the good stuff at reputable garages? If so that could help quash that cop-out excuse of theirs. If there were widespread fuel issues locally then the local papers would be all over it and you'd have heard something.

Hi all,

Just a quick update, had the car back since Wednesday and it seems to be running fine, have been on a few "spirited" drives and so far so good. Have mentioned to the garage that I only ever use shell or bp, but they said that all the checks they have done on my car have been ok and they haven't been able to reproduce and of the issues!

Today though we saw  a nail sticking out of drivers side rear tyre, went to get it looked at and they pointed out a chunk in the tread on the other rear tyre where canvas was visible, so 2 new conti sport 5s on the rear.

On the subject of the fuel claims, my Dad has starting problems with his Volvo XC90 and ended up with them claiming it was contaminated fuel, whilst the vehicles was in warranty they washed there hands of it and gave him a £2,500+VAT bill (which interestingly included a new ECU).

After a long battle and an independent mechanic and solicitors letters he managed to get his money back.

Seems that fuel is that grey area when it comes to warranty issues that dealers can't solve.

Hi,

Following on from the issues the other week, I have been using a different petrol station, but have still had the occasional mis fire, nothing any where as serious as last time, and none of them have produced warning lights, but still strange that they are happening...anyone else on here had any noticeable mis fires recently?

Going to email the dealers and see what they say, but I suspect that without any warning logs, they wont be able to do a great deal!!

Cheers,
Phil

Sorry to hear about your problems, the dealer is fobbing you off with the 'fuel contamination' excuse, it sounds like you have a genuine ongoing misfire.

Do you know if they've checked the basics such as the spark plug condition, coil/injector/sensor connectors are engaged fully, wiring loom condition (no chafing), fuses/relays are all seated properly, earth bolts are tight? If the engine is misfiring it's due to incorrect fuel/air mixture, a faulty component or connection. You could remove the plugs yourself and have a look at them, if one is obviously a different colour/condition then that tells you which cylinder has the problem. Try replacing that plug. If you're getting no joy from the dealer you could do quite a lot yourself to help diagnose the problem just by some elementary checks under the bonnet. I would start by checking the connectors on the coils and injectors (check they're 'clicked' on fully and check the pins aren't pushed back inside the connector), check the plugs, the coils are fully engaged on the plugs (with the plug and coil removed, ensure the coil engages properly with the top of the plug).

Hope that helps!

cheers

John
