Yeh, been there done that, about 6 or 7 months ago. Connector was fried and a hole melted in top of fuel pump, with strong gasoline odor in car. There is a thread on this site somewhere recording my experience with it. Replaced pump and connector. Odor is gone but CEL still on, despite my attempts to clear it. Read that one guy sprayed silicone in his gas cap and it went off. Maybe I'll try to get lucky that way.

Might be gas cap, might be the fuel pump seal? I do not recall how tricky the fuel pump seal was at the tank.

You need to get the exact code(s) as there may be more info about that.

Also did you file for reimbursement for the fuel pump as I think BMW is buying?

I felt pretty good about how the seal went on. I just read on here last week about the warranty extension or reimbursement (maybe?), but have been more preoccupied with the misfire. Not sure what proof of the repair/pump purchase I have saved. I would like to get access to the letter or form, whatever, to seek reimbursement.

The new coils arrived this afternoon. Ran right out to the garage when I got home this evening and replaced numbers 1 & 3 (which were originally 4 & 6 before I moved them). Fired up the X and, what do you know, no misfiring! Then went ahead and replaced all 6 and took for a 5 mile highway test drive. No doubt to me the engine is smoother and more responsive than it has been in the 10 months we've owned it.

The new coils look exactly like what was in the car. They say Bosch and have pretty much all the same writing/text/markings on them, except they were made in May 2015 instead of April 2009. If they are counterfeit, someone did a really good job on the outside.

CEL is still on as I expected. Assume that still has to do with the evap leak. Maybe that will be the start of another thread.

Wonder if anyone knows about how much the stealership would charge for the diagnosis and replacing just say, 2 coils?

You mean one coil.

:stickpoke

Glad you got it fixed.

Still thinking I got 6 for way less than their 1.

From my experience, it often seems if you take a vehicle in to one of the stealership garages and it is under warranty, they will usually replace the one coil/plug/whatever is defective and tell you that's all it needs. If not under warranty and you are paying, they'll advise that you really need to replace the entire set and 3 or 4 other things under the hood while they're in there.

You guys think I should hit the Clear Codes button in OBDiiFusion now?

You can clear the codes at this point.

Once you replace the coils, you will need to driving the vehicle for a few days then you should Log the data again and see where the Fuel Trims are running just to be safe there is not something else going on.

Just an update -- it's been several days since I've had a chance to get back on here. The X is humming like a sewing machine with the six new coils. I'll hook the OBD Fusion back up soon and get a log.

2008 X5 3.0si. Got code P0301 several weeks ago; replaced the #1 cylinder coil and spark plug and the car ran fine until 2 days ago. This time the code is P0304, for #4 cylinder misfire. Got new coil and spark, removed the engine cover; there is only enough space for 2 fingers to get to the #4 coil from the fire-wall side. There is a big cylinder right on the top-right position of the #4 coil.

I have not been able to remove the #4 coil and need expert advice for this DIY. 2 photos of the #4 coil are attached.

PS: (1) An online Youtube clip says replacing spark plug are easy but only shows removing the #2 coil/spark plug. (https://www.youtube.com/watch?v=OtzN-rwO8Yw) (2) The editing window's "Insert Image" only allows upload from an URL which I don't have. Copy and Past of photo doesn't seem to work in this post.
