Just bought an a4 B6 I believe, 2004 1.9 TDI 130 quattro estate with 85k on the clock.
I booked the car in for a clutch as it was slipping top end. Whilst it was in I decided to have the DMF done too because I felt as if the clutch pedal was really rough. I also provided the garage with a clutch bearing sleeve (genuine audi) as I thought this may be worn causing the rough pedal. Anyway, it's still not cured...800 quid later! It's really spoiling the drive of the car. If the engine is off the pedal is lovely and smooth. Sometime pressing the pedal is smooth whilst the engine is on but is especially worse when driving. It's noticeable when pressing the clutch pedal and disengaging it. I can feel the engine vibrating basically through the pedal. Now I know it's NOT the clutch and flywheel as they're literally a week old and have been replaced with quality OEM parts and the problem was there before and after. Also the thrust bearing and sleeve were also replaced.
Searching google and forums there are masses of stuff on the DMflywheel but eliminating this, is it possible I am feeling a vibration from another common problem....the alternator clutch? I have noticed vibrations and rougher feeling in the clutch when I am parking the car in a tight spot, say parallel parking and have full lock.
What's your thoughts? I have had a few 130 pd engined golfs but this audi is being spoilt by this issue..any help/advice appreciated. thanks..Daniel
