Passat GTE 2017 - Gearbox Fault
Hello ladies and gents,
I’m the proud owner of a 2017 Volkswagen Passat GTE, but unfortunately it recently broke down with a gearbox fault.
The garage carried out a full diagnostic, and these are the fault codes that were found (stored as sporadic faults):
* P060700 – Transmission Control Module Performance
* P07A300 – Transmission Friction Element “A” Stuck On
They also checked Volkswagen’s Technical Product Information (TPI) database but found no relevant bulletins relating to these faults.
A full Guided Fault Finding test was then carried out, and the conclusion was that the transmission mechatronic unit has suffered an internal failure. The garage has recommended replacing the TCM/mechatronic unit with a brand-new one.
Before I commit to such an expensive repair, I wanted to ask if anyone here has experienced these exact fault codes.
* Was it definitely the mechatronic/TCM?
* Has anyone had their mechatronic repaired successfully instead of replaced?
* If so, who carried out the repair, and has it been reliable?
I’ve already contacted TVS Engineering for advice, and they’re reviewing the fault codes to see whether this is a failure they’ve dealt with before and whether the unit may be repairable.
Mentioning im in the UK
Any advice or experiences would be greatly appreciated. Thanks in advance!
