RaihaX · 12-20-2011, 12:24 AM

Mine were an absolute bitch to remove Having not moved in 3 years they were welded to the plugs.

Patience, blood, adjectives and a twisting motion to "break" the seal eventually worked. To my surprise the ring you pull on can take a lot of abuse. As you are replacing them, at least there is less stress than trying not to break them!

Good luck.

As you're using a screw driver or similar to pull the coil pack up, just check and make sure you're not catching onto one of the wires that's around there.

By the time I got to the 4th or 5th I was getting over it and wanted to just finish already and almost ripped a wire as I pulled up.

... it'll make more sense once you're doing it.

Other than that, the guide is pretty good.

Sounds good thanks for the heads up!

Hopefully my coil won't be stuck as the spark plugs just got changed last week during a service.

The local dealer has it for $90/each vs $44/each from the states. I only bought one first to replace the one cylinder 5 (been having occasional misfire when doing third gear pull for data logging). Need to order the other 5 from the states.

btw out of interest the cylinder 1 is the one furthest away from the cabin and cylinder 6 is the one closest to the cabin correct?

Don't want to be changing cylinder 2 instead of 5

Yep I just used a screwdriver to 'leverage' them up...

also keep the coil packs clean (i.e. in their box until absolutely needed to put them in) to minimise chances of dust getting in etc.

Yeah only took it out the box once just to make sure I got the right part. Will keep it in the box till is time to install it!

RaihaX · 12-20-2011, 01:40 AM

Forgot to mention the do we need to disconnect the battery when doing this? the DIY didn't mention that (unless I am blind!).

ansch · 12-20-2011, 01:53 AM

didn't disconnect battery when I changed sparkplugs

car didn't burn down

RaihaX · 12-20-2011, 01:55 AM

Good to know - hopefully everything goes well tonight. Seems easy enough!

ansch · 12-20-2011, 01:58 AM

yeah... taking all the cover and cowling off is the time consuming part. If they just changed your plugs last week then they should come out pretty easy.

RaihaX · 12-20-2011, 02:09 AM

should be alright then - taking off the cowling I can do in my sleep with the number of times I have done the procede install and helping friends do it too

Should buy the spark plug socket tool so I can do that myself as well!

Dackelone · 12-20-2011, 05:48 AM

I used a 1/2 inch ratchet extention (12cm long) to insert into the coil packs to remove them. I did not want to use a screw driver bc I think that might cut or break the coil pack's rubber "pull loops". I have read that the pull lopps or even the rubber around the coil packs can break - IF they have been left sitting in there awhile.

You should change the spark plugs every 65K kms and then evry 60K kms after that point. My tuner says just to change them every 50K kms.

I used BMW spark plugs made by Bosch because I had read (on the e90 forum) that aftermarket spark plug can cause some missfires. Even spark plugs that are made by Bosch and have the same number - I read can cuase a missfire. There must be something about BMW-Bosch plugs. I'm not sure. All I know is I did not want to do this job twice. I used BMW plugs.

The spark plug order is correct. Germans always number cylinder #1 at teh front of the car (away from the pass area/firewall).

Here is my spark plug DIY...

Just changed it! it is so easy, why would I even pay someone to do it for me... all this years haha...

I guess next time I need to change my coil pack or spark plugs I will do it myself.

Anyway I went for a quick drive and I kid you not but it seems my car is soooo much smoother. It felt like before my car had a slight hesitation and now is just so responsive and the power just comes on.

Will be doing some logging tonight to make sure everything is all good!

RaihaX · 12-20-2011, 07:18 AM

By the way does anyone know where I can get the N54 spark plug socket tool locally?

I could get it from BMS but is $19 + $30 shipping

Get the meth kit and the socket at the same time, hehehehe

Smiley1175 · 12-20-2011, 04:21 PM

I got mine off eBay from this guy Clicky

Careful with the ebay plug tool, there was a chap on the e90 main board that had one iirc and it shattered with devestating effect

Smiley1175 · 12-20-2011, 05:27 PM

I've had no problems with it. I need to buy an extension socket thingy, I'm currently using two smaller extensions to reach down to the plugs and when I pull the plug up and out inevitably one of the extension bars disconnects which was the most frustrating part.

RaihaX · 12-20-2011, 06:37 PM

Just bought the socket and ordered the other 5 coilpack from Dan!

BMWRX · 02-13-2012, 06:03 PM

Hey Rai, how did the car feel after you replaced the other five coils? Any different? Is the part number W0133-1848325?
