Hi I have a 2007 grand punto dynamic sport, last year the alternator blew and we had it replaced but ever since the blue tooth and computers haven't worked and the mileage flashes, I took it back to the garage and they checked the alternator and the battery and said all were ok and they suspected it had blown and internal fuse and the electrics were beyond their remit and to take it to the dealer, Any ideas or suggestions from anyone? I want to sell it and don't want it to put anyone off the car runs fine it's just those bits that don't work
Thanks

Whilst I don't know much about it myself I have read that the flashing mileage error can be fixed with a "proxy alignment". Don't know if this will do anything for the bluetooth error though. Maybe a search will turn up more info for you.
