2000 bmw e38 740i sport

[Rikze38]

Hey guys I am Ricky and a proud owner of my beloved e38 1/15 mora Metallic search E38MOB on Instagram it’s all around on there.

This is my first post


E38 running rough since last summer. The car runs rough and shakes

It is a show car / weekend car so just this week got time to fix it. Thought it would be something small but I was wrong

Replaced:
OEM coils
NGK plugs
OEM Cam position sensors

It’s had a full over haul on the cooling chain guide vanos units most of the car has been replaced by oem parts about 1000 miles ago

Took out the 3-4 ignition coils while running and didn’t make any difference showing they are not working

Checked all wires to the dme unit no cuts no burns

Dme is dry and connections clean and dry no corrosion


Could it be the dme unit internally ?

I am
Hoping timm will be able to reply as he is a legend here in the uk


Thank you all in advance

hey there

thank you. I did have my friend mechanic come and plug the car up I will try get the codes up today
as far as I understand it was one of the cam shaft sensor that was flagged.
we changed them both for oem ones from bmw

Did the trouble start after the timing chain guides were done? If you can pull coils with no change in how the engine is running, you should have current codes. We really need those details to help you further.

hey mayourchuck

the fault code

3e misfiring at several cylinders
22 function inlet camshaft control bank 2

[Mayorchuck]

I strongly suggest you recheck your timing. Did you do this work yourself?

Not sure if you found the answer but I just went through this exact same thing with my e38. Mines a 2001 740i. Bank 1 was dead, only running on cylinders 5-8. Found the bolt that holds the camshaft in had come undone cam wasn’t spinning with the engine causing the multiple cylinder misfire. Retimed the motor and now running on all 8 again.
