If the coil tested good, more likely your "Camshaft Position Sensor" needs replacing if no "Sparks". When cam sensor failed/bad no sparks will produce. When the sensor malfunctions, the computer does not know when to fire the injectors and may not fire them at all. The faulty readouts may also throw off spark timing, which will affect the car's fuel economy. This sensor is used in conjunction with the crankshaft position sensor to control ignition timing. It is common for heat and oil leaks to cause this sensor to fail, due to where the sensor is located. In addition, parts like these, get a genuine part from Mercedes Benz Dealers or Pelican Parts online, its cheap, I don't recommend to get an aftermarket when it comes to electronics.

Sounds to be a loose or corroded wire/s at either starter motor or at battery fusible links.
Also check the earth strap (Cable) between engine and bodywork.
Hope this helps, MMP

Hi
Did you mean oil light ?
If so.... have you checked your engine oil level ?
If this is a diesel, perhaps you mean the cold start glow plugs light ?
If this light does not go out, the problem is in this department, normally fuse or the relay.
If it is really cold, this is why the engine will not start, as the glow plugs are not functioning.
Good Luck !
Don´t forget to give me a FixYa rating, almost a Guru !

check your main harness wire. The harness wire becomes brittle and will eventually short circuit your car. Stalling and hard starting is the initial symptom. If not replaced soon, your car will smoke and eventually affect your computer box

This can not be reset by conventional methods. This must be done through a scan tool. Usually only the dealer scan tool will communicate with the SRS module. If the SRS light is on you have other issues and they must be remedied before the light will go out. There is no way of knowing what the issue is without running codes with the scan tool.
