Having trouble with my ABS light and system. It first started with abs light and red handbrake light coming on flashing and beeping!! Turned engine off and back on and it would clear. The other day whilst braking lightly my abs came light came on and could feel it under the pedal. The abs light comes and goes which I find strange. I've used vag-com and the code is 18057 power train date bus and the other code is 01316 abs control module, no communications. Is my abs unit screwed? I've checked fuses on top of the battery and are all ok. Any help would be appreciated. Cheers
