While driving home in the evening and near my house, I braked behind a car and my ABS/BAS/ESP lights appeared and stayed on. I parked the car at my home and had a malfunction indicator on my instrument cluster. The next morning I got in the car and there was no malfunction indicator and I attempted to start it, but the car would not start or go in gear. I was able to turn the key in the ignition, but the engine would not crank (no sound), and the car would not come out of park. I had the car towed to a Mercedes Dealer, who diagnosed the problems as the car showing faults in the shift selector and transmission module. I have an 01 E320 Sedan with 75,000 miles. Prior to this incident, I did not have any problems with the car going in gear and starting. The Dealer wants $2600 to repair the car. Does anyone have opinions on what the problems could be with my car. I suspect the problem could be a simple electrical issue.
