Audi A4 2000 1. 8t (1) abs light flashing. Brought to dealer. Quoted $600 for repair kit, $1500 for new module. Both prices do not include labor. Searched internet and hundreds of other Audi A4 owners have experienced the same issue. (2) abs is now intermittent on my car and warning light is on constantly. (3) can't correct right away b/c my Audi dealership is 6 months back ordered. I assume because so many owners are experiencing the same problem.
