Re: Audi A6 4F C6 V6 2.7 3.0 TDi Buyers Checklist ....
All dates are approximations within this thread for parts ...
So you must allow for older parts being in the supply chain ...
From 2004 - 2006 the crankshaft vibration damper was poorly produced ...

Customer statement / workshop findings
Loud rattling noises from the engine compartment at start, at idle speed and when driving.
Power steering assistance may be stiff or various warning lights come on.
Technical background
The vulcanisation on the vibration damper of the crankshaft has come off. As a result, the outer ring of the vibration damper wobbles and knocks against the inner ring. In extreme cases the vibration damper can damage the front of the seal flange. Because of the wobbling of the vibration damper the belt drive (for alternator, water pump,
power steering pump and air conditioning compressor) can vibrate and the idler roller (plastic roller) of the belt tensioner can get very hot, so that the plastic roller can come off the bearing shaft. As a result the belt can fall off and the units supported by the drive fail.
Production change
Improved production.
A6 from Chassis number WAUZZZ4F*6N 167806
Measure
1. Replace the vibration damper (use new mounting bolts). Fit an 8 hole washer
(Part No. WHT 000950A) between the bolt head and the vibration damper
.
2. The belt tensioner and the
mounting bolt M10 must also be replaced.
Consequential damage to other parts can occur ...

Before I got my car I read a review in an auto mag which said "Audi ownership can be notoriously expensive"
From where I sit they were not wrong ...
