Lightbulb Cylinder 3 Misfire

Hey guys. I have a problem, couple days ago my 98 528i start shaking and after that i got check engine light on. The code is P0303 (cylinder 3 misfire detected) and i just changed my spark plugs last month and i also checked all my coils they are working. And no leak from anywhere. The mechanic said it might be the valve, and it will cost $300 to $500! Didnt sound good to me...How can i fix this problem?

Thank you Apram.

There is only one answer to your question.

You need to get the diagnostic trouble code that triggered the SES light.

Autozone will read it for you for free in most states.

How did you check your coils? Have you tried moving coil pack 3 to a different cylinder and seeing if the miss fire moves?

Have you removed the plugs and checked they are ok? Tried replacing them again?

Are there any other fault codes (e.g. fuel trims)

A valve would cost a lot more than $300 to $500.

Likely bad ignition coil.

I have a few Bremi coils for 98 528i laying around.

If it is the coils, a /coil F3 in the bestlinks netted the following:
- How to test a BMW ignition coil (1) (2)

I don't consider those threads all that wonderful for testing coils, in and of themselves (other than the basic hints) ... so if the OP comes up with a better procedure, please let us know so all benefit.

Note: The second link though is great for general misfires!

As for the DTC, the OP needs to go here first:
- How to help someone who has an SES but hasn't read the codes yet (1)

I tried everything and still I have misfire on cylinder 3.

There is no other codes only P0303 (cylinder 3 misfire detected)

You probably overheated the engine recently.

Typical for cyl 3 head crack on 528. I find coil packs usually don't fail.

You might be better off finding a good used engine. Cylinder 3 problems often come with a cracked head on that cylinder. Some have weilded the head and been OK--but there'e going to be alot of down time here--I would think somewhere around 2500 bucks for the fix--u might find a used engine cheaper in the long run.

cnn, how did you know a misfire was related to a overheat / head gasket?
Is this a common explanation for misfire? (Vs a bad coil which seems to normally be the case)

I think the most 'common' explanations for a misfire are here:
- How to diagnose a BMW E39 engine misfire (1)

I think cn90's logic was that the #3 cylinder is generally the one that cracks when the M54 overheats.

So, a persistent misfire in #3 without any other explanation is cause to do a compression check of #3.

Many estimates are in the threads I reference for you (everyone asks the same questions!).

If you buy a Bentley repair manual, head gasket jobs aren't that hard to DIY but I recommend finding a machine shop to deck the head before reinstalling it. You can DIY for a couple hundred bucks at the most

Yep.

Same engine (M52) I did in December, cost me a little less than $1000, but I did literally EVERYthing. Vanos seal, CCV, ALL hoses, injector o-rings, and even replaced a couple lifters and chain guides. If your lifters are all good, you won't have that expense, but if you have it all apart, I do recommend doing the VANOS seal, CCV, and every last hose you can reach.
