VR6 - Timing chain problem
just to introduce me, my name is Florian and I am from germany and I am looking for some help with regards to my timing chain problem of the VR6 since I can not find any good help in german forums other then "Replace the engine"
My Touareg is from 2004 and has 241PS (Horsepower). It was running now for 118000 Kilometers / 73k Miles.
Just to be clear on some tasks, I did change my oil every 10k kilometers or in a period of 10 month, so what comes first will be done.
At arround 112000 kilometers I started my car in the morning and the yellow engine light was on. I was suprised, because I was not facing any issues with the car, simply the light was on. I was going to Volkswagen and they found 1 sporadic/intermittent error which they simply deleted. The guy said to me, if the light turns on again, I should come back.
There was nothing for about 1500 kilometers and, guess what, the light was on again. So again I was going to the same Volkswagen dealer, and we did actually the same as it was not a permanent error.
Ok, again there was nothing for about 1000 kilometers, then the light turned on again and I started to check in the internet about that, I found my german forums and also threads in here that it is a timing chain issue. Wow, for a car which is 12 years old and was running 73k miles.... frustrating. However, I started to investigate and in 90% of the cases, it was that the timing chain needs to be replaced and since the VW engine is lengthwise in the car, you need to pull it out, repair it and bring it back in.
The interesting thing about this is, that there is no unexpected noise. I was wachting videos on youtube for audi/touareg which had a timing chain issue and there is a clear which I dont have. I have been told to check the VW engine with a USB controller to check the (hopefully correct translated) reading blocks 208/209.
This does show the values for the camshaft and crankshaft. Both the values are -10
I have been told that this is not good at all and I will face some serious issues.
Anyway, I know the Option to do that which would be arround 3000 Euro in total qt Volkswagen, however, I got some advices that I could try one thing before pulling of the engine and that is the replacement of the "upper tensioner".
Normally, to fix the timing chain issue it is required to pull out the engine, however, some Audi owners told me, there is a chance to replace the upper tensioner without pulling out the engine. In case this one is broken and can be replaced, there is a small chance that the problem is resolved since the chain itself does not have the issue. In case that this was not helpfull, I know that the remaining option is to pull out the engine.
Actually I am looking for some feedback if it is possible to replace the part and if there is a chance that only this piece is broken and is causing the issue. Volkswagen told me that the other tensioner is sitting on the bottom of the engine and this is bad, the piece itself is quite cheap but getting the engine out is 5-6 hours
Looking forward for some answers,
