I have just ordered a
Vagcom and am expecting it tomorrow, sadly I think I am a little far away from you. However I already own one of these
http://www.boutiqueobdfacile.com/
I think I paid about £15 for it, its easy to use and set up.
I have a issue with a sensor in the manifold that came on a while ago. I got it inspected (all documented on the forum somewhere). Anyway, the light has been off for over a month then came on again today, plugged this in, the fault showed up same as before and then I cleared it... Hey presto its gone away.
This will tell you exactly what the fault is so you can decide if its a 'nothing to worry about' like mine or a 'oh bugger I need to sell one of the children' thing.
Hope this helps
