A mate of mine has had a complete nightmare with this exact retro-fit!!!
He booked his 05 Plate GTI into a VW Main Dealer for a Longlife Service & Cluster swap. The dealer asked what the cluster was from, (2007 Mk5 R32) and they said it wouldn't be a problem, (20-30 mins for fitting and coding apparently)?.........
3 Days later, he has finally got his car back and Vw couldn't complete the job.
Day 1. All was going well until they tried to code the cluster and at first were having problems with the mileage change, but that soon changed to a multitude of issues. Apparently the cluster wouldn't allow VAG Commander to remove all of the old coding from the original car, (R32) and caused communication issues with the convienience module.
Day 2VAG Technical were sent e-mails for a "Wipe Code" for the R32 cluster, so in effect the unit would be like an off the shelf job. VAG Tech in Germany then became involved, and were working on the car remotely trying to solve the coding issues as there were still comms issues. End of day 2, VAG Tech couldn't get the R32 clocks to code up properly so advised Vw UK Agent to re-install the original cluster. This then opened up another series of problems, as the old clocks then started to refuse coding work. Aparently he was told that it appeared that the old clocks now had 2 sets of info, part from the R32 clocks and part from his car. At 18:15hrs the engineer had told my friend that he was going to download some info onto his USB stick to take home and see if he could work out what was going on
Day 310:30hrs, receives a phone call from Vw Dealer stating that the car was still causing problems and that they still couldn't even get the thing started??? They eventually phoned and confirmed that they managed to re-install the old cluster and got the car back to its original convienience settings!!!!
Now..... I'm not 100% perecent sure if this was VW just playing silly games or that they genuinely couldn't do the job, but to say that my friend is annoyed is an understatement. Especially when they charged him for a portion of the labour and didn't discount the Service
He still has the R32 cluster and i've told him that i'm convinced that they would work on his car, but he's not so sure??
This was something that I was also considering but this has made me a little worried
Any advice guys?
