Electric side door fault- soft opening not working

[andrewyzfr6]

Hi I’ve got a 2020 t6.1 with ten electric sliding side doors
Offside door isn’t working properly- won’t open with handles or on key- but only as you turn ignition on and push button on dash at same time. The button also flashes, then stays lit up constantly
The exterior handle dose not work at all(like it’s locked. Interior one releases latches heavily (not soft opening like it used to) although when losing the soft close works.
I’ve swapped the motors and control units in rear wings, the relay(they are like relays in the doors) and the unit the Bowden cables from the interior/exterior handles mount into. Problems stills stays on same side.
Any ideas please?

Same issue N/S sliding door. Flashing switch when stationary and then solid when driving. Was working perfectly and then nothing. Any assistance would be appreciated.

I eventually found a control unit in the osr wing(in front of tail lamp, removed and opened it up to find it had water ingress. Cleaned up and touched joints on circuit board with a soldering iron. Refitted to find lights off on dash! Had to re synchronise(?) with vcds. Worked for about 3 days. Bought a new unit (about £500) and now it’s fine.
