My Q7 with the 3.0 Superchsrged has only adjusted timing due to chain wear by a degree or two from last I checked. 8 degrees is considered immediate chain replacement, and I have 100k miles
Owner reviews for timing chain
I have a 1983 Benz 300TD with almost 400k miles. -ORIGINAL CHAIN
Gasoline direct injection turbos are subject to problems with soot and fuel dilution. This combination is especially problematic for timing chains. No matter how good the oil, you can't beat a reasonable oil change interval for ensuring your oil doesn't have soot in it.
I ended up spending 800 on genuine ford parts and did pulled the motor myself and took it as a challenge. Took me a month because I had to reorder parts and I was working a lot. The job is very hard and complicated and I have been working on cars for a good while. The good news is it runs like a champ now and it’s got 250k miles and I’m gana milk this truck for all it’s worth lol.
Ford equivalents use double link chains for the timing system. They last much longer than Mazdaspeed timing chains and are quieter. Reliability wise, they are solid. People use them all the time for speeds and beat the hell out of them.
Front axels, timing chain and tensioner, and that’s it for 80,000 miles. I thought the timing chain problem was addressed by Audi. Nope. But love it and it runs great.
Check engine light came on in our 2014 Q5. Turns out the timing chain needs to be replaced. At the same time the vehicle is burning excessive amounts of oil.
18 months ago the timing chain catastrophically failed causing extensive damage to the engine & costing me £15,000 for a complete engine rebuild with genuine Porsche parts.
Never used cloyes on belts. I used to use them for chains but had several failures over the last few years. Seems their quality has gone downhill.
gen 1 gen2 VVT issue when the timing chains where stretching.
