hope you got your money back
Money refunded this morning by Alex when VW were able to extract a different code form the unit itself.
In his defense, the code VW acquired from their own database was the same one he provided originally so in essence his service works but is at the mercy of correct/incorrect data on the VW database.
VW confirmed that the database is 60/40 at best but this comment was "off the cuff" so to speak so probably should not be taken at face value.
I would still recommend Alex as his service was quick and relatively cheap if unlike me, you don't have the option of a mate in VW to scan the unit for free.
