I have a BMW 328i 2008- the car was driving fine- and all of a sudden I stopped for just a moment. When I came Back to turn on the car it wouldn't start- when i pressed the break to turn the car on it was extremely stiff and the engine wouldnt even try to start. It has a new battery and recently had service- what could be causing this?

If you're talking about the Anti-Theft Security code for your radio, I'm fairly sure that only a BMW Dealership would be able to retrieve and reset the radio.

You could also try disconnecting the battery terminals for 10-20 minutes, and see if it resets.

check the starter

you need to disconnect one side of the battery, put one lead from an ampmeter on the battery post you have disconnected and the other ampmeter lead on the cable you took off the battery. with nothing turned on on the car , all doors closed the reading on the ampmeter should be no higher than 0.17 amp, if it reads a lot hgher go to the fusebox and remove one by one all the permanent supply fuses looking at the reading every time until you find the circuit that is causing the high reading, this will be the drain. alot of the time it can be central locking system playing up, boot light, glove box light not switching off, stereo wired wrong. hope this helps.

Possibly. 1st have the battery checked though. Pull it out and have a parts store check it (free service). All the lights may work, but the battery may not have enough 'juice' to crank the engine over. Is there a click, or no sound at all? Check terminals and connection at starter also to make sure all are clean and tight.
If battery checks out as fully charged and ok, then pull the starter and have it checked out. Good luck.

Your sensor is going bad or you have to change your oil.
