Bmw 318 e46 cold start problem / cuts out

Having trouble starting my bmw in the morning when its cold. I've taken it to two garages and there are no fault codes on the computer. I've replaced the MAF myself but it does not it seem to have made a difference. When its warmer I can start it easier, I need to rev it a bit then it will idle at around 1000rpm, seems fine on the open road too. Any help would be appreciated.

Made a quick vid which shows the issue.

Hi. I have had the same problem for 3yrs, your cold is not as bad as ours but I have changed nearly every sensor and hose and still no luck. Good luck. Jim
PS Start with your vacuum hoses.
The older I get the wrong bit gets stiff!!

Check the sap hose from pump to valve...check the valve for a clog in the inlet (from decayed hose collecting inside it like mine).

This happened to me once (318i N42 engine). I just had my solenoid o-rings replaced.

I removed them, cleaned my solenoids and installed them again. Then the sputtering went away.

Check the fuel pressure. The fuel pump may be failing.

What are the trouble codes you read with your OBD code reader? Not sure if your car has an OBD plug or not.
