MasterCheck your battery and charging system, low battery voltage will cause all these lights to come on. If the battery and charging system are OK, then you'll want to get the diagnostic information from the vehicle, and this can only be done with the appropriate equipment from a repair shop.

MasterYou'll need to take this to a good Mercedes shop and have them check all the diagnostic codes in the vehicle, have them check all the related technical service bulletins from Mercedes and they will come up with an approach to how to best fix this.

MasterThis is an electrical problem, and if it's related to the water in the vehicle, then it can be very difficult and expensive to address this, however, you will want to start by having the shop check all the codes in the vehicle, and double check that they didn't leave anything loose or disconnected when they put your car back together.
