Please help, I have an 2012 SMAX 2.0TDI 163 Powershift, the car starts fine and will drive fine under very light acceleration. However as soon as any load is applied the car jerks followed by an ESP warning light and a message (or multiple/flashing) message/s saying 'ESP off', normally followed by an "engine malfunction" and "transmission malfunction" the car then becomes difficult to drive and eventually the IPC displays many lights including ABS and the speedometer drops to 0 before finally losing all drive (but engine still running)
I have replace the PCM and ABS modules and also the battery.
It might be coincidental but both the front doors have trouble locking and unlocking when the remote button is pressed.
Any help on this would be massively appreciated.
TIA
