My Ride: 318ci Coupe
Cutting Out 318ci Crankshaft Sensor?

Hi
New to the forum,
I wondered if anyone knew what might be causing this,
My car cut out when pulling off from a roundabout, All the lights came up, dtc, yellow handbrake light, and beeped.
I pulled over after ruling a few things out disconnected the battery which I heard resets the ecu? and the car fired straight up and I drove home.
Little later went out to the gym as I thought it was a one off and it seemed fine, did it again on the way there, same thing, disconnected battery and fired up got to the gym ok on the way back did the same thing again, however this time it would not fire right up and I had to wait about 20 mins and then again drove home,
Next day, stupid i know, risked it again thinking I would just have to disconnected the battery and maybe wait a bit, cut out at a junction. Wouldn't start for an hour, called recovery, started drove 100 FT and did it again then had to wait a further 2 hours for recovery.
I got the guy to plug in the fault code reader and it came up with these codes.

P0015 Exhaust (B) Camshaft Position Timing - Over-Retarded (Bank 1)

P0335 Crankshaft Position Sensor "A" Circuit

P0011 Intake (A) Camshaft Position Timing - Over-Advanced (Bank 1)

P0366 Camshaft Position Sensor "B" Circuit Range/Performance (Bank 1)

He said it was most likely the crank sensor as he could not hear the fuel pump but the car turns over and will start fine just not for long.
I have had the whole timing chain assembly replaced if that means anything as it was knocking before?
I will post a video below

The Car Is A 2004 318ci Coupe N42B20A

Any help is really appreciated !
Many thanks

Good that you read the codes. That said, I don't think all those sensors would fail at the same time.

What's the history of the fuel filter and fuel pump? Those could certainly cause the stall you described. Don't know if they would cause those codes though.

Just and FYI - when my Cam position sensor was going out the car would randomly stall from a stop especially under light throttle.

Thanks for replying to me,
Thats what i thought was strange and the car when it starts if it does sounds runs drives completely fine,

I did have the fuel filter done, dont know much about the fuel pump, but the car does have 128k on it, could it be the pump?

Cheers for the heads up on the cam sensors, its funny i got all those codes, could that mean there could be a problem with the timing chain again?
Thanks

Fuel pumps in our cars typically last for about 125k miles or so. I think poster jfoj figured that the pump will last about 5000 hours of operation. That means the pump will fail at varying miles. The pump will fail in two ways:
- soft fail whereby the pump does pump fuel but at a reduced pressure
- hard fail whereby the pump just quits

It sounds like your pump is in the soft fail mode. Buy a Siemens/VDO pump from an online vendor. Siemens/VDO is the original equipment manufacturer (OEM). Don't buy a pump from a parts store as it'll die in short order.

Cheers for the reply,
I have followed the diagnosis on another thread for fuel pump failure and you seem to be right,
I am going to change the fuel pump with an OEM one and will update the thread.
Thanks for your help
