A6 1.8T Engine Rattle
Hope someone can help me with this.
UK '99 A6 1.8T (150bhp) with 110K miles. Engine runs fine but have noticed
over last few weeks that between gear changes when revs drop to approx.
2000rpm a rattle is heard from the engine. Noise doesn't occur when engine
revs increase, only when decreasing. Does the same thing if sat stationary
and rev engine.
It doesn't sound like a plate/heatshield etc rattling in the engine bay due
to vibration, as I would expect this to vibrate at various rpm whether
increasing revs or decreasing.
Certainly sounds like something in the engine like a chain rattling but
don't know the internals of the engine very well to put my finger on it.
I would be grateful for any advice hopefully to tell my engine is not
terminally ill or if I can expect an expensive trip to the dealer.
Thanks
Ian

Re: A6 1.8T Engine Rattle
Check the timing belt tension. Open the cover at the front of the engine. It
will open enough for you to see in with a torch. The toothed belt should be
tight.
If it is loose then do not drive the car.....

Re: A6 1.8T Engine Rattle
Thanks for advice, I checked the timing belt tension and it is fine. Having
listened to the noise again it sounds like it's coming from the catalytic
converter. I assume it's the cat which is bolted on just after the turbo and
drops down by the bulkhead. Is it likely to be damaged inside and causing
this noise?
Regards
Ian.

Re: A6 1.8T Engine Rattle
Thanks for the feedback, it'll help when it goes in for its 110K mile
service when I explain the problem. Apologies for lack of knowledge on
engine, which end is the cam adjuster, as the noise sound like its coming
from the back of the engine down low (bulkhead end).

Ian.

Re: A6 1.8T Engine Rattle
Actually I have no idea where a "cam adjuster" is. If I had to take a
guess it would be in the middle-top part or the engine, but then
again, its just a guess. All I really know that it was bugging me a
lot until the dealer finally found it.
