    when the abs module goes funny is it the module under the rear seat or the abs pump under the bonnet?

    If you've got a non-quattro car then it'll be the module under rear seat. Got a vagcom? Check for codes, it is possible that the pump could have failed but unlikely.

    If it's a quattro then the module will be attached to the pump in the engine bay. I don't think you should have anything relating to the ABS under the rear seat? I may be wrong as I have a pre facelift quattro sport. Are you getting an error code at all?

    the module will be bolted to the pump, it's the yaw sensor under the rear seat.
