ESP and ABS light comes on when accelerating
 

Hello everyone

I have a 01 A6 2.7t with 125k miles on it. Lately when I accelerate past 40mph to pass someone the ESP light (the one with the diamond with a circle around it) and the ABS light comes on and the transmission slips. When this happens I take my foot off of the gas and lights go away and everything is back to normal. This doesn;t happen all of the time but it happens often enough. I just had the mass air flow sensor replaced but the problem still persists. Doe any one else have or had this issue so I can get it repaired?

Thanks

Use a vag-com to scan for codes.

My initial guesses, and they are no more than guesses, are the brake light switch, wheel speed sensors, or transmission issue. Vag-com will help you diagnose much better.
