Not Sure what to make of this but the wife drove slowly through a deep puddle yesterday about 10 to 12 inches. Parked the car up when starting again 2 hours later lots of warning lights came up and started scrolling , Chassis warning, Head light leveler, PMS etc. It was dark when she got back so looked at it this morning now dashboard wont light up. Car starts but all switches dont work for the central consol i.e. raise lower suspension, turn on sports mode, turn on e+ e- or the media centre. But if you remove fuse 53 on drivers side Steering column switching module (UK Car) They start working and all the warnings start scrolling through. Its a 2016 Cayenne hybrid. Error via the OBDI port is showing communication error between chassis computer and main computer.
