VR6 ABS issue

Right,

All sensors changed
Rings cleaned
No fault codes
ECU Reset

ABS light comes on but no vibration from the pedal preceding it.
Where do I go next?  :smiley:

I would put the car on VAG com measuring blocks to check if it is registering each wheel speed.
Is the ABS light on all the time? i take it the brakes are locking up.

Have not had the right time to test the brakes yet, but the light comes on at ignition and stays on or just comes on while driving. I have a signal from each sensor too......

Get someone to read the wheel speed on each wheel on VAG com, or have you already done that?
If all else fails i suspect the problem is the ECU.

Vag com shows wheel speed in normal limits, what about relays or abs pump?

OBDII has pump and ECU as one unit.
You could try the relay, but i suspect the ECU.
