My BMW 316TI Compact will not start. The engine turns over, but it keeps flooding itself. Any suggestions? Thanks

Petrol in the cylinder can be caused by a badly leaking injector as well. Check for spark in the other cylinders. If no spark there, it can be the anti theft system shutting the engine off. Check for fuel pressure. Remove the air filter cartridge and spray some starter fluid in the intake. If the engine tries to start, you may have a fuel pressure problem (pump or clogged filter)

faulty fuel pump, - check for spark by pulling one of the spark plugs and holding ht lead close to engine block, check when turning over for lightning spark from lead to block, if you have spark then i would suspect fuel pump

Could be cam shaft sensor or crank shaft sensor first comes first diagnostics to see codes but bmw come up with loads of codes that arnt the problem.

Some cases is:
Vacuum leak
Cam shaft sensor
Crankshaft sensor
Eccentric shaft sensor is a main problem on these cars and maf

bad radio or loose connection.

CD player is broken. Replace radio unit.

Yes, it could be the door switches.If the door switches aren't on the B pillar, then they are within the door lock mechanism and you will have to remove the inner door skin to get to them.

See the information attached, and use the common sense, and logically. God bless you
The CD/DVD, has 2 switch one for open and another for to close. the swicth can be dust, dirty, or defective.Test the power switch for dirty, dust, or defective.
The unity can be dissasembly, and make troubleshooting, diagnose.
I can recommend you to go the repair shop. When the switch is NOT open they NOT send the signal to the SYSCON(CPU) or microcontroller.
God bless you

my 2003 bmw 316ti se id doing exactly same as this but also a rough idle when started from cold. it cuts out at most junctions etc when putting on breaks and pushing in clutch, starts no problem. it drives beautifully when out of town etc no overheating etc. please help. i just had a mechanic on it for 5 hours with no solution.

there was a fault came up when plugged into diagnostics (MAF sensor) but checked maf sensor and it is a new one so erased fault code and hasnt came back so assuming this wasnt erased when new part put in.

Can you give me some more information? Does it run fine if you do not apply the brakes? This could be a failing brake booster and you are loosing vacuum when the brakes are applied....

The vehicle owner's manual will contain that information.
