So you've got the ABS light and the master brake warning light on - but no codes in the ABS ECU?

What were you reading it with? Have you checked all feeds and earth to the ABS module?

brake warning light and abs light - TonyW
I'm looking forward to the continuation of this thread - I think we may have the same problem on a 2000 1.8T. I'm only an amateur (and the professionals have come up with nothing yet) but my suspicions as to its origins lie in an electronics problem with the ignition. Firstly the radio went dead & didn't respond to any laptop checks. Fortunately the ignition problem was discovered before the new radio was delivered & the radio came back to life - but then the abs problem. Firstly quite intermittent & random (eg i could do 100 miles with no problem, then it'd be on for 200 miles etc) but recently I haven't gone more than a few yards before the beeping starts.
