heya folks, was stopped at a set of lights today and suddenly there were 3 or 4 low pitched beeps and the speedo went bonkers, was at a standstill but it was jumping from 10 to 40... Any ideas folks?

Have a garage plug an FCR into the OBD2 data port. Likely to be a speed sensor fault, probably the one for the speedo.

could it be anything to do with the fact that i'm running VRS alloy wheels on a car meant for 14 inch steelies?

No, all you would get is a slight speedo error due to different rolling circumference. As the fault happened while stopped at lights, it's definitely a sensor fault. A fault code reader should give you a better idea of the problem.

ok, thanks for that. I need to find someone with vagcom then! I can live with it for now as it has only happened once and has made no difference to speedo readings when on the move.
