Question MY 2009 E550 was parked in a parking lot at a hotel out of town. The parking lot flooded during the night. The water level was below the rear bumper. The water level was just above the lower rim of the tires in the morning when I was informed that the lot was flooded during the night.

The remote did not work. The hotel staff tried the remote and was able to enter the vehicle. The vehicle was started and water flew out of the exhaust. The vehicle was moved to the front of the hotel the screen was red with ABS and Battery messages. The vehicle locked up. After an hour the vehicle started up with the same messages on display.

The interior carpets were wet and there was some muddy water up to the tracks on the front seats. The front seats were not working and the defroster was not working.

The dealer said the vehicle needed a wiring harness and it would take six weeks to be made by the factory. The vehicle has been with the dealer for almost ninety days. The dashboard was removed all the vehicle was rewired. The vehicle may be able in a week or two if all the codes checks out. Is this a reasonable amount of times for replacing the wiring harness?
