Hey guys I'm brand new to the Audi world, had some questions, I've been looking at an s4 v8 05' with 130km on it looks very clean and I'm going for a yet drive today , what are some stuff I should be looking for ?

I'm so happy I moved on from that v8 engine, way too many issues...

If your set on it though make sure to get a compression/leakdown test done and check for the chain rattle at start up.

The cars maintaince history is also very important, oil changes every 5000km with full documentation.

Regarding the timing chain issue.. im looking at buying an 05 S4, only has 124,000 kms on it. ive heard it start from cold but i wasnt listening for a timing chain, would it be really noticable or do you really have to listen for it? should i be worried buying this car?

I would avoid the "bastards" (2005.5). Go with 2006 or later.

Joey - how many miles on your S4 with the timing chain issues? Were there any signs before it failed?

Axel - when you say avoid 2005.5 in favour of 2006, are you referring to the chain issue specifically? if so, what changed on the 2006, the guide material?

I dont know what the chain noise sounds like on these cars, i cant help there sorry. I had a VR6 years ago and had to change the guides on that. The noise was pretty obvious, a clear ticking noise at a very specific rev range, went away completely at other rpms

It's not specifically a guide thing. It's the fact that the 2005.5 is actually a B6 in a B7's clothing. A bunch of stuff changed and improved with the B7s from the B6s and might as well go with the updated components from the B7 instead.
