Is the ecu flooded? Worth trying a battery off re-set. Plenty of advice on here if you do a search.

It sounds suspiciously like a Kbus fault, just out of curiosity does the car have sat nav drive and tuner? if so have a look to see if there is water in the spare wheel well.

Similarly if the car has an aftermarket head unit fitted, it may be worth checking the switched and permanent +ve are not transposed, and also check the white and red wire with yellow flashes (K-Bus) wire is not connected to something it shouldn't.

Also if the car is wired for memory seats, make sure the wiring under the drivers seat specifically has not been trapped and damaged.

It can be a long and drawn out process to trace faults of this type, but hopefully this may point you in the right direction

Best of luck and let us know how you get on please.
