A6 Avant 2001. Stutters only when warm, during fastacceleration, accelerating slowly= no stutter.
Background,sat for about 6 months, battery died. Brought to service station for checkup, they put oil into cylnders because they could not start. I dont understand why. Inoticedoil around spark plugs, so I replaced plugs.
The car was running fine before it sat for 6 months. I got acompany car and my wife usedmy old vehicle-thats why it sat. We were not sure which 1 to keep.
Also, all the lights in dash are on and radio is in safe mode.
Any ideas?

 

maybe your maf sensor needs to be cleaned, it can cause a stutter. A mechanic told me to clean mine with a q tip- very gently.

 

Thanks, that makes sense. Where is it in an A6 6cyl?

 

Sounds like your VC gaskets need to be replaced if you found oil in the spark plug holes.

 

maf sensor is int the intake duct work you have to have special bits that are hollowed out in the end as the bolts are tamper proof.

 

found it-thanks
