S4 V8 owners: a question...

Chip:

I'm certainly no expert on this engine and others who frequent this NG may be of more direct benefit. One of the writeups I read about the new 4.2 liter engine that is used in the S4 is that it creates more engine noise. In redesigning the engine to fit into less space Audi moved the timing chain/belt to the back of the engine and they say it makes more noise in the passenger compartment. You should check with your dealership's service department to make sure yours isn't making an unusual noise. However, the noise you describe is consistent with the noise I would expect from a timing chain/belt.

Thanks Aar. That might well be what it is. I will probably check with Audi, but 2 things put me off doing this:

1. I feel a bit "silly" asking them. Its an engine. Its makes noises. What do I ex;pect????
2. (more importantly) the muppets in the service dept probably won't have a clue anyway.

Cheers,

Chip.

Chip:

Agreed. That's what they're there for. Taking it to them and opening a service call for the noise creates an early audit trail for future use if it turns out to be a problem.
