I had this on my A6. No smoke though.
The engine was rough near idle and jerking.
Tandem pump changed and the problem is sorting it self out.
I had the tandem pump changed they also cleaned out the fuel tank.
Best way to check, is to remove the oil filter and cut it open. mine was black...
I have an Audi A6 2006 BRE Engine. 88k mileage.
I am about to get the KMB kit changed in the oil pump. Timing belt will be done at the same time.
Is there a guide, how long will it take once the Oil sump is off.?
Can you provide the list of Parts you mentioned above.
Any help so I can...
