Diagnostic Light

Can anybody recommend where to buy an OBD handset tool for a VW MKIV Golf?

I am looking to reset a engine diagnostic light, the car was serviced recently but I don't want to go back to the garage just yet. Preference would be to turn off light myself and then bring back when light reappears.

Is it just the service indicator light which you wish to reset?

No, it's the actual engine diagnostic light.

I was looking at getting one from this crowd in England. No affiliation and haven't actually ordered yet but look at what they sell and you can cut and paste the type of OBD readers into google. You might get caught for tax if you order from the USA. (I did on a car stereo).
