2004 S4 rumble noise on start up
 

Car has 135,000 kms...engine and clutch were replaced at 65k...car makes a weird clunk/rumble noise on start up...not all the time...sounds like it has something to do with the clutch...anyone have similar experience? Any input will be appreciated!! Thanks.

If it's more like a "rattle" it's apparently a normal noise.

There's tons of info in this thread for you :)

Thank You!!! that makes me feel much better....was worried I'd have a very expensive repair bill....Thanks again!

it could also be chain tensioners...which are grounds for shitting a brick but is usually nothing. Our engine is driven by timing chains, not a timing belt.

here's another good thread...you may have to join to read (not sure?)

Thanks for the info....it seems not as loud with the warmer weather.

The first post in that link sounds alot like the possible crank-knock I heard in an S4 I test-drove.

Hmmm... More reading.... :rolleyes:

If your running a lighter weight oil compared to what Audi says should be used then try the OEM weight. Thin oiling on the 4.2's can be misdiagnosed as chains / chain guides / faulty cam adjusters / etc all of which require an expensive engine pull if true.

Wow ok thats a good one... in fact the noise started about a week after the local garage did on oil change...... thanks
