I used the VCDS / OBD2 All-in-One Kit and it works very well.
The extra software package is very nice too, although I must admit that for me and maybe for others too, it would have been very nice if it had an english version (or I should start learning very seriously german :-)).
Thank you very much for an excellent and fast service.
[Edit Kaufmann Automotive GmbH: Thanks for your review! Meanwhile KDataScope and KPower are available in english (VCDS itself has always been available in english language).]
