Title: abs warning light
Post by: jocarl11 on 23 February 2010, 20:40: I bought my car with the abs light not working! So today i finally got round to investigating why, I already guessed it would be disconnected and supprise supprise it was! I reconnected the plug expecting to get a constant warning light when i turned the ignition but the light still didn't come on at all?? So my question is what would be my next step? I'm gonna check the fuses tomorrow but even if thats been taken out its almost certainly to hide a fault :angry:

The bulb may have even just blown seeing as they do come on every time you start the car any way for a few seconds. Try connecting Vagcom up to the vehicle to see if there are any underlying ABS issues, failing that maybe get another warning light from a breakers or Ebay for pennies.

Post by: FlySpeck on 24 February 2010, 01:46: the entire unit can be disconnected, it lives under the rear seat base squab and if its unplugged, no abs or light is shown. My brothers previous vr6 had a weird abs fault in that over 20mph, the abs would start braking by itself, under 20 no reaction, so we pulled the main plug out of the controller and that stopped it, no lights were shown after that.

The previous owner may have had the same problem, and done the same thing, tho as has been said, could have been down to a sensor signalling that the wheels were spinning free hence it tried to brake to control wheelspin that wasnt happening...

No the airbag light doesn't come on either! As i say when i took out the lights they were not plugged in so i plugged them in and still nothing, i had a quick look at the bulbs and they looked fine!
