Re: Customer service?
What you really need is VCDS from Gendan, comes in a kit with a decent OBD connector, but it iasnt cheap, however it does all of the Diagnostic stuff with VAG cars, and you can make tweaks to your car depending on the model, for example on the Seat Leon 1P (aka the mk2) you can set up the auto park mirrors, reset the digital speedo from Kph to Mph or vici verki, turn off that annoying "second fob press required to unlock all the doors... and other stuff.
The licence can be pruchased for a limited number of vins registered or fully unlimited (you wouldnt want that). It wasnt cheap but... buy cheap buy twice as they say.
We got it for the Leon FR and my Octavia VRS, I think its pretty much paid for itself so far, and as licenced users we get updates to both the program and the obd connector drivers.
