Parked my 318i BMW now wont start can anyone help please

If ambient temperature was high it could be just a vapor lock. I'd try opening the fuel filler cap and then replacing. Otherwise would need some more information such as the year, transmission type, previous most recent issues with starting

Most likely engine is seized. Put a socket and a breaker bar on camshaft nut and see if you can move it if not engine is destroyed

sounds like a engine sensor i'd guess at the crank sensor but to be sure you would need to get the OBD codes read , this will give the exact fault so wont waste money trying sensor(s) on a hit an miss basis,you can buy a code reader online not expensive just make sure it covers your vehicle make then you have a valuable diag equipment for future use

check fuel pressure

could be a problem with the security chip in the key.

sounds like crank sensor

something in the airbag system is at fault. it could be the airbag(s) itself or any of the sensors that detect a crash to deploy the airbag. i would really take it into BMW and have it checked & repaired. the airbag(s) will not deploy with this light on so your safety is at risk if you are ever in an accident..

it is your starter motor burnt out.need anew one.

I would have the battery tested. When they get cold they get weak. Next I would look at the wires on the starter to see if their loose.

Hello there

If you drive an automatic and it starts to judder at low speeds than that means you transmission isn't down shifting as the speed is reduced. In the first instance you should get your transmission oil changed.

Hope this helps and please don't forget to rate me.
