my experience w coils is as follows. my 325 03/06 had a coil gobad at 114k. i own a shop thspecializes in bmw so i had a few other e90s. i had an e90 there w a 07/06 build date. the coil went into valve cover perfectly fine but the electrical connection would not plug in properlt.
im also wondering why so many are replacing them as a set? i am at 190,000 miles as of today and only neeeded to replace that one coil.

For my production day it says 01/06 as per picture below, that means january 2006 right? not the 1st of June? lol just making sure

So in this case this should be a no brainer for me, I have to get the pre 03/06 ignition coils right? with the ILZFR6D11 NGK spark plugs?

yeah, January '06. get the older coils and you'll be good to go. Can't remember exactly what plugs I got, but they were whichever NGK platinums were recommended

nice, thanks, btw the old style coil are a little bit cheaper than the revised ones

Sorry to be so long without saying anything here. They are absolutely the wrong part. Spark plug makes no difference. Dealer sold me the wrong part and won't exchange it for me. Typical, these coils are for sale at a loss. Do not trust your build date. Pull a coil and match it up.

I am having the same problem

My car is a 2007 328xi with original 0 221 504 467 ignition coils. Now I am trying to replace them but I cant find the right parts. From my serial number the new parts number is suposed to be 0 221 504 470 but them dont fit right on my car.

Like pizza party said the new design doesn't let the spark plug sit correctly on the ignition coil and the engine run hard with missfire.

Does someone has found a solution for that?

[mimik]

Yup. My car is 2006 e90 325xi with a build date of 06-2006. I had a bad coil P0305 on cylinder 5. Changed the 6 sparks to the NGK iridium once and I replaced only one coil. The new coil which is the correct one for my car is 0 221 504 470 or part number that ends with 937. Regrettably, it does fit snuggly onto the spark plug. Went to the dealer to get a different coil but they insist that one they sold me is correct. The 936 ending part number is for turbo engines, not non-turbo engines. He told to try pushing it down on the valve cylinder and add some dielectric grease. I am also experiencing misfires when idle and when the car is warm as well.

This sucks.

Has anyone tried to order the 936 coils (grey) that are for my non turbo 330i?
I bet they will work.

Probably goes without saying, but I would go according to RealOEM to find the correct part number for your specific car. Just took a look a moment ago - there are so many variations actually, checked against the various 330i models. Best is to actually check the existing part that is in your car, then cross reference with updated and compatible parts. for example, my 330i has the first coil pack type for the N52 which had the off-centre tab on the plug - this was used up to 04/2006. The newer coil pack type had the plug with the tab in the centre (same as the M54 motor BTW - same part numbers).

Those are E46 coils, they won't work.

Well, this is what I was saying. My 330i being a 2005 model uses the older coil pack type with part numbers 12137548553 and then later upgraded to 12137594936. This according to RealOEM.

My Wife's E46 320i (M54B22) uses 12131712219 and then later upgraded to 12137594937 which is the same as the E90 330i from 04/2006 onwards. Again, according to RealOEM.

Just a few weeks ago I needed to replace all 6 coils on her car since another of the original coils was starting to fail - it wasn't causing a misfire enough to feel when idling, but it was causing a stumble at low revs when setting off from yield stops. I had one go bad a few years ago and just replaced that one at the time, but if one goes (especially considering the age and mileage of the car), chances are the rest will follow. So I decided to just replace them all now. In my searching I noticed that ECS Tuning listed the original 12131712219 coil pack as being superseded, then that new coil pack was also superseded, until eventually it showed 12137594937. It also showed that this was compatible with E90 N52 engines which intrigued me! My first thought was that I was always convinced that our car's coil packs were different, now all of a sudden it seemed like they were actually the same.

I then remembered that there was a difference that some coil packs have that off-centre tab and others not. So with the old original one that had failed in hand, I looked at a photo that I had taken of one of my car's coil packs when I had changed the spark plugs, and noticed that the tab was off-centre, so therefore NOT the same! This had me confused. But, then checked RealOEM again and saw what I have mentioned above.

Anyway, I ordered a new set of Bosch 0221504464 (their part number to replace the 12131712219) and what I like is the fact that these are the newer one piece sealed type, and not the older grey type that is susceptible to damage from oil leaks around the plug hole gaskets. Luckily I won't have to worry about that for a while, just recently replaced the valve cover gasket and fitted Beisan Systems Vanos seals. Some pics of the old and new coil type (new on the left, old on the right):

And you used those on the E90?

No no, on my Wife's E46 320i. And the also replaced the spark plugs since the car is so close to 200k km (120k miles). No, these won't fit on my car due to the different placement of the tab on the plug. But, if my car was manufactured from 04/2006 onwards, then according to RealOEM and ECS Tuning they would work. So all I can think is that it's probably more a case of having different spark plug harness than anything else. Not sure why they did this, but anyway.

What if your production date is 04/2006 (as is my e90 330i)?

Probably only thing you can do is to go in and take one out and find out which style?

Do the coils have an actual number on the part?

Thanks in advance

It should be - here are the ones from my 330i:




I think since yours is 04/2006, it should theoretically be the same as these. If not, I would be curious to know!

[gryphun]

I just took 1 out and will post pics later

my car has a 5/2006 build date, and still uses the older plug with the off-center tab - even though nearly everything I found online says my car has the newer type with the centered tab.

Here are the pics...

part number on the coil
inside the coil chamber - nice and clean (dealer replaced valve cover gasket back when car had 50,000 miles)

[Three_thirty_I]

Yep, 12137551049 is the newer type with the tab in the centre, and therefore 12137594937 is also a newer replacement for this - so technically, the E46 M54 type coil is the same for your car.

That is weird - what does RealOEM show if you put your VIN in and search?

real oem says:

01 - Ignition coil - DELPHI - 04/2006 - 12138616153

Does it show this: http://www.realoem.com/bmw/showparts...17&hg=12&fg=05

[mike-y]

not exactly, that's for the 330i, I have a 325i. but they both actually list the xxx-6153 part number "from 4/2006".

Of course, 325i - keep looking generally under 330i. But it still seems to be the same general "family" of coil pack (they just list a few of them on the 325i compared to the 330i in those links).
