Hello to you all.

I recently bought a 2008 335i It had 52k on the clock, full service ect...
Anyway not long after I bought it the car went into limp mode, had it diagnosed and changed the vanos solenoids, which solved that issue.

Now I am on 57k and for a few thousand miles I've had a lumpy idle, long cranks worse when cold, however when warm still idle shake. Doesn't throw any codes, I changed oil and plugs, to no avail, however when removing the old plugs, only done 10k, cylinder 1 and 5 were highly contaminated with what I think is fuel.

Would I be right in saying I have two bad injectors? Leaking into cylinders causing a long crank?

As I am in the uk bmw want to charge me 200 gbp each injector, so does anyone import them to uk I could get some cheaper. Any advice is really appreciated thanks.

Long crank sounds like a hpfp

My idle also has a slight "sputter/lump", if you will. I'd be curious if other have this issue as well.

My guess is carbon build-up being the culprit.

It's likely your injectors, I have the same issue with a brand new HPFP, LPF sensor, plugs and coils too. My #2 cyl plug was black, and smelled like gas so I'm assuming it's leaking.

Does anywhere sell and supply to uk? I'm gonna try changing the bank, sure this is my problem I know a lot have hpfp and carbon build up but my plugs are covered in fuel so sure mine are just bad injectors. Any more help welcome
