Hello. There are a few problems that can cause this. If there is the correct fuel pressure and if there is compression, then the sensors need to be checked with a scan tool to see if any of them are not reading correctly. Most of the time this is caused by a bad crankshaft position sensor. This is a common failure on most of the Mercedes engines from this year. It can also be a defective air flow meter, but the crank sensor is by far the most common. If you are planning on having this crank-no-start fixed, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this.
