Hi all,

A suberb came into my friends garage with the following problem - gears won't engage - if we put it in drive and accelerate, it revs as if it is in neutral. And unable to connect to gearbox control unit with VCDS.

Specs of the car:

Year: 2010
Model: Superb 2 3T
Engine: 1.8 TFSI Engine code CDAA
Gearbox: 0AM DQ200 7-DSG Gearbox code MLC

So we ordered a new TCU with software pre-loaded. Set it up and it connected to VCDS and there is no DTC stored in the TCU, but was unable to complete basic setting of the transmission (tried performing it with both ODIS and VCDS):





With vcds, I determined that the hydraulic pump is not working:





So we got hold of another valve body and set that up, now pump is running (I can see in VCDS), but cannot perform basic setting and now these DTCs are stored in the TCU:

another problem I found was that the tcu is reporting clutch status as 'invalid' (I check on another good car these fields have correct values)



Any ideas on how to proceed now?

Hello

Are the gear forks installed right?And are they moving ?
And when you but on the new tmc did you removed the cover from the ventilation.It is secured when the new tmc comes.And pump cant build pressure if it is secured.
