just bought a 2007 saab 9-3 combi sport tdi 1.9, had the transmission service and it starts playing up, slipping when go from 2nd to 3rd gear, the service center told me it could cause software, it may need to have it updated and said that the unit is all boxed in, nothing much can be checked.
and does it need to take 20 minutes to update the software?. and is it possible to check what level of software it is running?.
HELP
