cold start problem

bizzleb109 · 12-26-2015, 01:13 PM

Hi I have a 2007 335i auto when cold it idles really rough the engine light came on and flashes. Turned the car off a couple of times once the car is warm it's fine purrs nice to to drive. When starting the car I don't get long cranks or anything. Just a couple of days ago had a service done and coils where replaced as well. I was thinking it was the hpfp but after reading on forum feel that it's not that cos I don't get long cranks when starting and once warm the car is fine. Any ideas pls?

Thanks

Leaking injector filling cylinder with fuel while the car sits since you mention that it's fine after you start it a few times and warmed up. 07 model so you probably have the early fault prone injectors still.

I suggest you address this soon, as leaking fuel into cylinders will thin out your oil and cause some real damage
