Hey guys new to the site and new to owning an Audi, but my ABS light is on and I'm not sure what needs to be repaired, from cold start its not there but it stutters when stoping almost as if it were wet and the ABS is engaging. After about 20 minutes or so the light comes on and the brake light then flashes until the car is stopped need help and insight greatly. Thanks in advance

 

I'd really bet that one of your ABS sensors is dying. Only wan to know which one is to get some VAG-COM codes. It would show up right away there.

 

Thanks I'll start there first.
