If you cannot find simple solution, something a little leftfield (just thinking about the rain!), but it may be worth checking if there is any water/damp under the passenger side carpet (caused by blocked drain in the passenger side cowl under the windscreen (lift the bonnet, and look down into the passenger side vent for signs of water or blockage)

- There is a lot of canbus wiring under the passenger footwell, and from experience, having mositure there can throw up a lot of weirdness / faults (to the point my W220 could not get drive authorisation due to corroded wires, (dead on the key turn to start, though everything else seemingly ok) -

But as the others said - Check the codes - probably something simple
