A friend of mine with a 4.2 was doing work on his car with the battery off. He was re connecting at the under bonnet posts as and when necessary but, with his mind elsewhere he connected the wrong way round ! Result, his mmi is dead and he is out of ideas, does anyone on the forum have any? Main reason I ask is because I want his wheels and he can't put it in jacking mode without the mmi. (unashamed)

Get the car scanned with something like VCDS, but I'm surprised it's only killed the MMI system. Also check the fuses, as if one model on the MMI bus is dead the hole MMI system is dead.
Many thanks for the reply, I'll pass on the info and try to get a more detailed list of dones and not dones. Rod.
