2008 Audi S6. 50k miles.
I experience Variant 1 in drive and Variant 2 in sport.
Temperature, etc seem to have no effect.
Dealer says car is ‘normal’ and made no fix. I even had the service manager drive the car for a day.
An independent Audi specialist recognized the problem, indicated ‘someone’ was working on it. Made no changes.
Nothing close to resolution.
Variant 2 in S can be VIOLENT. I do not use the S mode for this reason. I fear breaking something
