You have a problem:

how does the car just try to switch to electric after turning off the gas engine? does it automatically turn the gas engine back on? does this next sequence repeat itself over and over again?

    You can run a diagnostic test on your car and see code P309D Hydraulic pump pressure problem in automatic transmission DQ200 DSG7 0am JETTA HYBRID.

    Possible repair requires replacement of the oil seal of the clutch drive K0.

    But you can't find this part in a VW shop because the dealer can only sell the mechatronics unit or the gearbox assembly.

    If you want to buy this part, please check how many seals you need, usually only one is damaged, you can only replace one, but both seals need to be replaced for a good k0 drive repair
