The engine suddenly stops while driving.

Hi boys and girls!

The engine suddenly stops while driving. This happens about every 10 km, but never during the first 10 km after a cold start.
When the engine stops, the red lamp with the battery symbol lights up.
Often the engine stop is only for a short moment before the engine starts again, but sometimes the stop lasts for some seconds.
Some few times I have to stop the car and start the engine again.
But it is never a problem to start it again.
I read the trouble codes with PA soft 1.3.6, but there were so many errors that I decided to erase the error codes and run the car again until I have got some new errors.
See the error codes below:

DME:
Error code 2781(hex) Camshaft sensor, intake
Error code 2731(hex) Inlet camshaft control
Error code 27BB(hex) Exhaust camshaft control
Error code 277F(hex) Crankshift sensor speed (I suppose it should be Crankshaft sensor speed)

ABS: (This two errors was from the beginning and I was not able to erase them).
Error code 5DF4(hex) Power supply to low
Error code 5E1A(hex) CAN DME/DDE signal error

I should be very grateful if you could give me some ideas how to solve the problem.

It sounds like you have an electrical issue. How many miles are in the odometer? How old is the battery? Does the car have the original alternator? These cars are full of electronix and they do not like low or erratic voltages. I suspect your alternator is in need of repair.

Re: The engine suddenly stops while driving.

I would examine the battery. Also examine the power steering reservoir and see if the hoses coming off of it is leaking fluid on your alternator. Are you having to add in power steering fluid all the time?

The battery is only 1 year old.

I have erased the fault codes again and made a new trip until the motor stopped again for a short moment (about 0,5 sec).
After that I read following codes in DME:

Error code 2781(hex) Camshaft sensor, intake
Error code 2731(hex) Inlet camshaft Control

Looks to me that it has something to the with the camshaft sensors.
Could that sensors cause the motor to stop?
Or could any other faults cause this error codes?
Anyone how knows the functions of this sensors?
Very grateful if you could help me.

Yes, change the sensor. Remember to get an oem sensor or you will regret it. Not necessarily a genuine bmw, but the same manufacturer of that part originally for our cars

Anyone else have insight here? Similar array of errors. A bunch of weird ones coming from the DME, through INPA but getting P0365 - exhaust CPS through my regular OBD scanner. DSC unit has similar error codes as well. Let car sit for an hour and now started up fine. I cleared errors and am waiting to see what returns.

I first tried to replace the inlet camshaft sensor but it did not help.
Finally I replaced the crankshaft sensor and now the car is running fine.
But I still have some fault codes for the camshaft sensor.

How about checking the engine ground.
Any chance that there are some electrical issues and what you are seeing is a symptom not the cause.
You might want to check the right hand engine mount (mine was cracked and did not provide good ground)

Ground issues were my first thought. I'll check the engine ground. Battery ground checks out.

The fault codes from the camshaft sensors was because of a slack cam chain. After replacing the chain all error codes was gone.
It is possible to check for a slack chain through the oil filling hole.

Maybe on your 318; no such access on the 6-cylinder models.
