I own a 98 a4 1.8t quattro. Lately I've been sinking some money into her to fix some overdue repairs. One of them being the ABS module. The abs light, and brake light have been on for roughly a year now (abs light is solid, brake light blinking.. and also the three really annoying beeps everytime you turn the car on). My first step into solving this problem was to run Vag-com and see if I could communicate with the abs module. No communication at all. I couldn't even access any other modules without removing the ABS module fuse. After coming to the conclusion that the ABS module is most likely faulty, I matched the part number and ordered a remanufactured module from autoecu.com. Just a couple hours ago I installed the remanufactured abs module and ran Vag-scan. I was able to communicate with the controller immediately. Scanned for faulty codes... Nothing. No codes at all. But.. My abs light, and brake light were still there. Pretty disappointing. I tried disconnecting the battery for 30 minutes hoping to reset the ecu and clear the lights, didn't work. I also tested the wheel speed sensors because I've heard those can cause the abs, and brake lights. The wheel sensors were all dead on according to vag-scan, all registered the same speed while driving down the road. So, I'm stumped. If anyone has any advice, or can think of anything I'm missing it would be greatly appreciated.
