Mercedes-Benz S550 Engine Performance Problems Due to Crankshaft Position Sensor Failure
Mercedes-Benz S550 Problem
Average Mileage: 61,678 mi (22,100 mi - 100,000 mi)
I purchased a pre-owned 2007 MB S550 (43,000 miles).
I encountered two problems;
#1. Engine check light comes on while driving on the road. The engine is shaking badly when the engine check light comes on and the problem goes away when I restart then engine with the key.
#2. Occasionally, I am unable to strat the engine. The engine would start when the gear is put in "N" instead of "P". Are these problems associates with Crankshaft Sensor Failure??

Won't even turn over. Battery fully charged. Slight, faint electronic noise for about 2 seconds. Then silence.
When I got my s550 3 weeks ago, it stalled as I started it up. It kept stalling. I didn't drive it must because I was going to get the car checked out at the dealership. I had just kept it in the garage. Yesterday I drove it to the bank, then I left and went to dry cleaners. Was in there 5mins. As I left car won't start up. I had. To get it towed to the dealership. Had battery tested(13.2 volts) Good Battery. Waiting to see what the damage is. I want the dealer to cover all cost.
