Try injector cleaner if its fuel injected

Sometimes you have to enter the pin manually. Most blue tooth pins are 0000 but some use 1234

That's a problem that will need to be taken care of at a shop or dealer , that has a computer that can configure the problem out and make repairs. With all the new electronics these days its important to make sure you have some one that has the right program to trouble shoot the problem.

Could be a few things, when was the last time you replaced your fuel filter? Could also be a faulty fuel pump. Also there is a sensor that is located on top of the bell housing unit . you must stick your hand between the fire wall and the engine. this is nothing but a magnet that detects the #1 piston in your engine.

Might have a code stored in the cars computer to aid in diagnostics. I would seek a scan tool, or hire some one that has one.Onboard sensors tecd to go bad in those models. (not cheep either)

Did you disconnect something or pinch the fuel line?

The causes for this DTC may include: Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors. Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0304 for number 4. A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture. A large air leak at or near the number one oxygen sensor would also cause a lean mixture. A plugged converter will cause of host of driveability problems as well as set this code. A severely plugged converter will result in the inability to increase rpm when under load. Look for a code such as P0420 -- catalytic converter efficiency below threshold if the converter indicating a faulty converter. A faulty oxygen sensor. This will set a code in itself, however, a faulty oxygen sensor does not automatically condemn the sensor. The code just means that the sensor signal was not within specifications. An air leak or any of the above will cause an erroneous signal. There is a multitude of O2 codes relating to O2 performance which gives a clue to the problematic area. The Mass Airflow sensor will also cause this problem. It would be accompanied by a code such as P0100 -- Mass Airflow circuit malfunction. The Mass Airflow sensor is a hot wire that senses the volume of air entering the intake manifold. The computer uses this information to control fuel mixture. Rusty exhaust systems, cracked exhaust manifolds or damaged or missing gaskets or donuts will cause air leaks.

Look in your glove box in the owners manual or with the papers you got when you got the car, and see if you have a card or a piece of paper that tells you what the code is. If not you will have to call your local mercedes dealer and give them your vin/serial number and they can look it up for you.
