The 3 series BMW uses a common rail diesel injection system. This means a high pressure pump provides diesel to a common rail feeding all 4 injectors. If one injector goes down there can be insufficient pressure to start the car. The 3 series BMW uses a common rail diesel injection system.

an air leak in the fuel system, timing out computer fault, lift pump faulty or failing,expensive. injectors dirty or warn, injector pump fault- expensive
Black smoke is : too much fuel and not enough air, a faulty injector (s). Take out the injectors and have them tested before you do engine damage.
Constant ground signal from the ECM, or injector could be faulty and stuck open.
Usually a sign of bad injector cups. Head cracking, bad fuel pump seals, faulty injectors, or fuel system restriction are other possibilities.
A grounded signal wire from pcm, faulty pcm, or faulty injector are the only possible causes.
That truck has two fuel injectors in the throttle body. I doubt that both are bad. I would suspect the fuel pump is faulty.
P0205 means that the PCM detected a fault in the injector 5 or the wiring to the injector. Could be a bad injector number 5. Maybe the wires to the injectors or the PCM is faulty.
Possible reasons the fuel injectors are not working: Faulty ECM (engine control module, computer) Faulty fuel injector(s). Fuel injectors clogged. Insufficient fuel pressure. Bad Ground. Faulty wiring otherwise.
The engine will run rough with a faulty fuel injector. More than one or two bad fuel injectors at one time would be unusual.
I've seen this happen with a leaking injector, a cracked head or an faulty oil cooler.
Fuel injectors are very precise, very fragile pieces of equipment.If one is faulty, you can attempt to clean it with fuel injector cleaner. However, replacement may be your best bet.
Typically that is caused by a little buildup of deposits around the inside of the injector tips. Sometimes you can put a can of injector cleaner through the system and clean out the deposits. Use the injector cleaner as described on the can. It may take a couple applications to clean the injectors. Sometimes that doesn't work and you'll need to replace the faulty injectors. Good luck.
