Hi all,
Thanks again for your replies!
I pried the cover off and found that the ABS light has actually blown...problem is that I can't seem to get the bulb out of the PCB and wondering if any of you have managed to do so?
It looks like it's in a tiny socket that's soldered to the PCB, but can't seem to twist/push/pull it out.
Took the car for a drive today and did an emergency stop at ~40mph and the wheels didn't lock, so have my fingers crossed that the ABS might actually be working - going to invest in a VAG COM kit though.
So, have any of you managed to get those bulbs out?
Cheers again

Chris
[EDIT: has anybody managed to get the VAG COM USB kits to work with Vista? Looks like most of them most likely won't work with Vista and are only compatible with the old version of the VAG COM software from 2004...]
