Phaeton spins, many mistakes…

Hi people Today I’m normally driving out of the garage and maybe 3km driven. Stopped and piiiieeeep, key symbol lights up with the message “System error workshop”. Now the following no longer works : – Can’t close with remote control – Climate not available – Windows no longer open – Turn signal no longer – Steering wheel heating and steering wheel lighting no longer go – Tempomat no longer works etc. Strange : – Car can be started, alarm system goes off – Interior lighting goes – Pulling aid funzt – Radio funzt – Screen funzt Does this have to do with water in the footroom? Footroom carpet Driver and passenger is dry. Greetz
