It is my car from the linked thread.
No, it is not sorted. I've been driving for the last 4 months with the warning lights on.
I have spoken to and emailed all sorts of people; some are more help than others!
My local mapper can't/won't touch it and says it's VW only.
VW UK don't want to know.
I took the technical bulletin to 2 main dealers. 1st said it was rubbish. 2nd one said they would try the software update if I could get the CD.
VW USA have given me the part number for the software CD (only $20), but I can't order one without logging into the ordering website (which I can't). They also can't say if it will work on a UK car.
Am currently waiting for someone at another main dealer to get back to me.
I fear that a new ECU will be the only fix, but I don't want to spend that sort of dosh if I don't have to. I hope you can get further with this than me!
