Control unit for rear end electronics - faulty

[Art]

The 4S has spent over 11 months in warranty repairs. Still it can invent something new!
I decided to visit local bakery and ended a 11 kW charging just to realize the car won't power up. This has happened before so I tried all the tricks. Power cycle, go out - lock - walk around ccw - open - start.. no. Display says key not found.
Catching another key. Doing bird-dance and voilá - power on! Moving few hundred meters and positioning it a bit for possible flatbedding.. Leaving powered to pick something from inside..
And when I arrived back it has shut power and trunk was open. I closed the trunk and while walking to get in - it opened the trunk by itself. Closed it again - and then frunk lid popped up! Then trunk opened again..

Ok. Time to call assistance and have my favorite flatbed to pull it on with rollers. 260 km to Espoo again on the reliable Volvo.

After 20 days 'Control unit for rear end electronics' changed and it's claimed it also clears the side airbag fault. A bit critical - I think.

Kind Espoo service drove it back to me and took back loaner Macan 4.

Haven't noticed this kind of fault on this forum before?

Outside the photo - trunk was taped to keep it closed. Frunk was hold with it's mechanical latch.

So it looks like this error was something rather unique? Not many comments here!
More unique than the DC heaters which - according to service history - seem to be changed 3 times already without I even noticed. Must be like air filter in 'brenners'.

Good part in this last visit was the possibility to see how 4-wheel drives have changed in over 80 years!
