I just saw this video that Cobb made to show you how to change out a bad coil or bad spark plug. I think watching this video will be a big help to anyone changing their spark plugs.

Definitely! Thanks for the link, I just ordered a new set of plugs a few days ago.

Nice write up...
Funky looking plugs, requiring a deep 12-point socket.

Thanks yet again Dack!
I'll be doing this in a few days time before hitting the track on Friday. I'm at 24,00km but had had a misfire code come up for cylinder 1 last month on track.

Did you fix(replace) anything when you got that misfire code? IF not... you might want to move coil #1 to say cylinder #2 - if you get a code for cylinder #2 then you know its your coil pack for that cylinder. |

By coincidence I had the code come up again (only the 2nd time ever), tonight. Gave it a bootful in 2nd gear, engine light came on and then ran VERY rough. Pulled over, stopped, restarted and all good again, but the new 29CD code remains. |

Hummm.... well... its (probably) either a bad coil or plug. Watch that Cobb video - bc it is easy to snap the coil packs back improperly. You have to make sure the electrical harness goes/slides back onto the coil pack correctly. Maybe someone was in your engine before and did not do that correctly? Or it could be a bad coil/plug. G.L. and Report back! |

I had my injectors checked & four were subsequently replaced in the 135 about 2,000km ago. Last edited by TimMc; 04-24-2012 at 07:31 AM.. |

Put new plugs in, swapped coils 1 & 2, deleted misfire code & went to track day yesterday. All good

It is quite an easy job to do. You only need a special spark plug tool and maybe a torque wrench. Getting that LR 6mm cheasehead bolt(allen) out from the corner of the valve cover is about the only hard part of the job. Go slow and take your time. Be carefull when tugging up on the coil packs - they can break(!). Watch that video... it really nothing special about doing this job yourself. IF you have changed the pollen filter or put in a pigg tune... you know how to do 90% of the job! Dackel |

What am I doing worng?
I just went to changed the spark plugs at the 90k point (the dealer did them at 45k) and when I went to start the car up after I changed them out I got multiple misfires from different cylinders...mostly 1 and 6. I followed the DIY on the site, torqued the plugs to 23nm, and made sure the coils were well seated. The car ran perfectly before I started. I bought the OEM spark plugs from BAVAUTO and verified that they are the exact same as the ones I took out. I've even gone as far as swapping coils and putting in the old plugs but that has fixed nothing. Any ideas? Thanks in advance! |

I would double check the coil pack connectors - it is possible to close them too quickly and the electrical connector doesn't sit correctly in the coil pack. Watch that Cobb video again to see what I mean. IF you STILL are having miss fires... I would remove those two cylinders(#1 & #6) and switch them with a "good" cylinder plug(from one of the rest, #2 thru #5) and restart up the engine and see IF you get any misfires. When you remove those two misfiring plugs... take a real close look at the gap. It is possible that one of the electrode tips is bent or not gap'd correctly. IF you have a spark plug gap gauge use it to double check the gaps. Or maybe just reinstall two of your old spark plugs for now. Maybe get two new ones from BAVAUTO. The reason why I bought my plugs at the dealer(more $$ I know...) was to avoid such a problem. Some say there is no difference. But I had read a few posts on the e90 forum about problems with using plugs from not a BMW dealer. Please post and let us know what the problem was. Good Luck, Dackel |

Thanks for the reply but I'm just going to throw in the towel and have it towed to the dealer. I'm so pissed off right now. I've already buttoned up the car. I flinch every time I start the car after swapping something and I hear the mess under the hood. I feel like I'm doing permanent damage. I'll let you know how it works out but since it's a holiday weekend I'm without a car for a bit.
BTW last time I got a 1, 3, and 6 misfire with a multiple misfire code. |

So... I got this PM the other day from J-Sud...

Btw... J-Sud told me in another PM today his dealer gave him the wrong plugs. So... J-Sud... I think you should post your part numbers. Also NOTE my failing memory as the plugs I used in my car were THREE pronged not four pronged. Dackel |

The original part number they gave me was 12-12-0-037-582, for my 2009, Spet 08 build, which are for the N55. Now just need to find time to change them since the long weekend is over! Dackel, thanks for the help, I hope this clarifies somethings for others. Remember, always check the part numbers that the dealer gives you.

The plugs I used before the misfire matched the part numbers that were in the car. Those new plugs are from BAVAUTO though. The car is with Mark at Northeast Motor Werks in Middletown, CT as we speak so I'll let you guys know what he figured out. BTW both plugs old and new that I had were 3 prong.

UPDATE:
I called Mark this afternoon at Northeast Motor Werks and he gave me the skinny on what he has found. First he ran the diagnostics and I still had misfire codes on 1,3, and 6. He then pulled all of the plugs and found that many of them were already pretty beat up and dirty. (Keep in mind these were new plugs when I installed them on Saturday). He checked gaps, verified they were OEM and reinstalled them. He started the car and it still misfired. He then reset the ECU just to try that and still got the misfires. He then swapped the ignition coil packs and the problem did not move with the packs. Up to this point these are things I had already had done, but any good troubleshooter goes over all of it again IMO. He had a brand new set of the OEM plugs in his shop so he pulled all of my new plugs and placed in his new plugs….car fired right up and hummed like day 1. So, this makes me feel good for a few reasons. For starters, it proves to me I’m not an idiot and knew what I was doing. Secondly it reaffirms the value of these forums. Dackelone was right yet again. I’m not sure if Bavarian Autosport stores their spark plugs in a pool or a fire pit or if they simply got damaged in shipping but they didn’t work. I can say with 100% accuracy they are the dealership sold OEM BMW plugs. I can also say…again… they didn’t work. So the moral of the story is stop being a cheap ass like me and just drive to your local dealer (if you can) and hand carry those plugs out of there. Thanks again guys! I’m getting the car back tomorrow probably as I’m having Mark do some other stuff. He’s great to work with and if anyone in CT is looking for an independent shop I would highly recommend him. |
