Bit of a long shot but I wonder if disconnecting the battery, waiting for 5 minutes or so & then re-connecting might re-set the unit?
You’d need to re-set the ESP (easy - the manual tells you how) & possibly the one-touch lowering for the windows, also the idling may be a bit erratic for the first few miles as the ECU re-learns the engine - but this might possibly be worth a try?
