A no start condition may develop due to an anti-theft system fault. If the drive authorization module fails to recognize the keys, the engine will not start. In many cases, a new module and keys will be needed to correct this problem.

I just changed the battery and now it will not stay started, It just keeps shutting off!!!
Went out to start it one cold winter morning and it would not start. Starter would engage but as soon as it would kick over it would stop. It was the key. Cost me $100 to diagnose, $141.50 for the key and chip, and $52.50 to program it. That is for one. But it works!

Car refused to start and MB dealer says All Activity Module has to be replaced. I have only had car for two weeks and now am stuck with the cost of repair of $2,150.00.
When I try to start the car, the engine turns over but immediately stops. It happens with every attempt.

WITHIN THE LAST MONTH, i HAVE HAD TO REPLACE MY ALTENATOR, THE EGR VALVE AND THE DRIVESHAFT POSITION SENSOR. AFTER THAT, ALL WAS WELL. SHOULD BE FOR THE MONEY I SPENT. BUT TWO DAYS LATER, I COULD NOT START THE VEHICLE. I WOULD GET A (START ERROR) IN THE DASH.. (START LOCK OUT). I BROUGHT IT TO MY MERCEDES DEALER WHO TOLD ME THEY COULD NOT FIND THE PROBLEM. I CHECKED THE BOOK AND IT WAS TELLING ME IT DID NOT RECOGNIZE MY KEY AND I COULD NOT RESET THE KEYS. BUT ANOTHER TWO DAYS THEY CALLED ME AND TOLD ME IT WAS THE EAM CONTROL UNIT AND WANTED TO CHARGE $1,575.00 TO REPLACE IT. I CHECKED WITH THE PARTS DEPT. AND THE UNIT ONLY COST $504.30. I DON'T KNOW IF THAT WILL CAUSE THE EAM TO FAIL. BUT NEVER HAD A PROBLEM BEFORE TILL CRANKSHAFT POSITION SENSOR HAD TO BE REPLACED.
Car starts then shuts down seconds later. Recently maintainced has done this ever since
