just thought id give an update on this:
vw55raz from e london(nice bloke) vdcs registered owner came down and scanned my ed30. we found an error related to "system too rich in idle".
had it cleared and it hasnt come up since yesterday...
not sure what caused this but its a recently purchases car and I think it had been sitting around for a couple of months before this...this might be the cause..
in any case im clear of any dashboard lights.......for now!
cheers
