Hi again.

The ABS light is constantly on from start-up on my 1998 A3 1.8T. I've checked the fuses and all of the relays for functionality and they all appear to be fine. I'm assuming it's not a sensor fault because as stated it is always on, even before the car has moved.

I haven't got a code reader so I would be incredibly grateful if someone could point be in the right direction in my next step of the diagnosis (with a multi meter, LOL).

Thanks in advance for your time and advice.
