What Audi found
'Trace fault to input shaft clutch plates updating from a 6 disc package to 7 disc package. Update gearbox ECU with new soft ware for the 7 plate package'.
All fitted and woking as new, what my farther said.
My Dad has had this fault over the past 6 weeks. His is a A4 2.5tdi multitronic advant.
Took it into dealers today and they said the gearbox needed modifying, instead of 6 clutchs is is now going to have severn, which he belives it will now have severn gears.
He will be getting the car back...
