Ok from what I know it's a version c manufactured in 2011.
The problem was it was running a lower firmware than it should have been originally, now it's running a 2660.
I'm worried about bricking it, and it maybe the unit is faulty I'm not sure.
Spoke to VW they go £2,000!
VW said they would charge me £60 to try a firmware update no guarantee that will work though, I don't want to spend money on repairs if they don't know how to fix it or if the unit is faulty.
Original owner is going to say not his problem I suspect when I get in touch.
