Advice on ABS error condition needed

[Albie 0]

Can anyone advise on a strange condition of my ABS on my 2.0L 16V? The ABS has never given a hint of trouble in 2 years.

 

Forgot to turn off the sidelights yesterday and in the evening the battery was flat. When I tried to start it, it turned a few times but gave up the ghost as it would do. However, the electrics went into a strange condition where the indicators for both sides, the ABS warning light, and the dashboard security alarm LED all turned on and I couldn't get them to turn off.

 

When I restarted the car with a jump from my wife's Golf, (which was easy at the first turn of the switch), I let it run to charge it for a couple of minutes, stopped the engine, reset the alarm, the indicators reset themselves, but the ABS warning light will now not turn off. When I start the engine it gives a little flicker as it used to but then stabilises and stays on.

 

The brakes seem fine, the fluid is full to the top mark still, but nothing I do will turn off the dashboard warning light. Can anyone suggest what is wrong?

Im sorry I cannot say how to reset the abs light, but is it possible that the problem lead to there being an actual fault? Therefore a sure fire way of finding out if there is a fault is to plug the car into VAG-COM, hopefully you can find someone off here or a local back garage that will plug you in for free. Alternatively, can a fuse cause this - worth swapping about?

ABS requires good battery voltage - maybe just needs a good overnight charge or replacement

ABS will report a fault if it's power feed drops below 8v at any time (even ignition off).

You need to scan/reset the faults in the ECU.

Have you tried driving the car? If the battery has been flat, a short journey up the road might reset the ABS and clear the fault? I''d give this a go if you haven't already tried it...
