I had new rotors and pads at all 4 corners replaced. After that I got "red" brake light on solid, "yellow" ABS word blinking, and the glorious 3 chimes. VAG shows no communication and gobs of low voltage codes. Battery 2 years old and no batt problems currently.

1. Where is the ABS fuse? I found a bank of 4 relays and 3 larger fuses/circuit breaker type-enclosed under dash on drivers far left side. Is it the last fuse on the right at bottom?

2. My hand held $60 scanner codes P0501 speed sensor code but no one seems to think its that and its a ABS control module.

I've disconnected battery and reconnected with same issues. I've now purchased the 30 amp circuit breaker type fuses for under dash to try. Could it be as simple as a fuse? Oh, and my speedo doesn't work either.

reference 2003 A4 1.8TQ

Please advise
