Hey all, I have an issue with a bmw z3 M54 2.2i. It keeps coming up with bank lean codes and misfires. Both banks and single banks, random misfires, but diagnostic says cylinder 5 is troublesome. No obvious vac leaks anywhere... fault has been getting more frequent, although the car hasn’t run much in the last six months... any thoughts??? Thanks.
I have the same issue, I replaced all the spark plugs but when it didn't fix the issue. I came to know that it was a bad ignition coil on cylinder one. But I am afraid to buy bosch or any other ignition coil as everyone here is telling me that all coils have to be from the same brand. but mine just say BMW BRIME like yours and I am not able to find those. Should I just buy the bosch one like you did?
Hii i have got a 2008 e92 Recently had a misfire in cly6 and it was a faulty coil. Anyhow i changed the coil and it ran well but recently while taking to high rpm the engine light comes on and when i restart the car its all back to normal. So, just wondering is it again another coil or any other issue
prabhjot singh next time the lights comes on don’t turn it off and go to autozone type store that will hook up an obd reader and tell you what code the check engine light is throwing. Might not be another coil. Tho after changing my first coil, every month after another coil when bad. So every month for 6 months I installed a new coil. I have all new coils and I recommend changing them all at the same time.
How do you pull out ignition coil no. 4, I was trying to fix my 2009 BMW X5 E70 engine but it was too hard to pull out and I cannot even wiggle it from side to side, do you have any suggestions? I was searching for an ignition coil puller but found nothing….thanks….
If anyone can help me i have a 07 328xi and it will rev high and somtimes if i let it sit it will rev high and then shut off also has a check engine on
Adrian Viciana clean it, keep an eye on it. Too much oil and youll lose spark and cause more issues. Oil in the spark well isnt the problem, the problem would be why is oil getting in there.
Smoove King theres a million reasons why the car could make noises or run improper. The three keys are air, fuel, and ignition. Youll need to know first if your running rich or lean. Do you have any scan tools? Can you make video i can check out?..
Rock auto parts caused more and more issues as i tried to fix them. Do not buy sensors ignition parts ect... Will never purchase again. Great it fixed the problem for a few months but your deffs going to be down on power
I ended up biting the bullet and went to the dealer. Right away i noticed a huge difference in the way it ran. The rock auto ones fixed the problem and all but there was still a slight mis fire. After i put the dealer ones it ran 200%
Sawier true. But that only shows there’s a problem there which could also be from a couple other reasons. And if someone doesn’t have an obd2 tool then this video is for those. But the point I’m getting at is it does not say “ignition coil #4 bad” it just tells you have some problem with that particular cylinder.
I Got A Bimmer! I’m glad you said that cause I bought coils for the cylinders that said mis fire but I also cleaned my vanos solenoids and it ran like a champ
