Today when my wife noticed that something was wrong with the SAV but really could not explain it. She said she thought the oil light was on. I told to come back home and let me check it out Turns out that the enginge light was on and it was some serious shuttering going on..

I got my handy OBD II reader out and read this...

What do you guys think?

SPark plug, injector clog, bad coil?

clogged injector would trigger a lean condition. I would bet bad coil, but it wouldn't hurt to try a new plug. ...or move the coil to another cylinder, if the error changes to the new bank its the coil.

ALright I did a couple of things but still have the shutter. I changed the coil to another cylinder, but the Service engine light did not come on. SO i am not sure what to believe.

Next while the engine was running I unplugged the coil to see if there was a change in the engine. There was on all cylinders. Can this be a bad spark plug?

Strike the last statement. I took it for another drive and what do you know the service engine light finally comes on. And it cylinder 1 now. I will be going to the parts store in the morning hopefully to pick up an ignition coil.

I use Rev along with this product

If you have an android device I would recommend getting the bluetooth version.

Paul, did replacing the ignition coil fix your problem? I'm having a similar issue and going to try the same thing to see if it's the ignition coil.

Yes it did fix my problem. I also bought additional one just in case another one goes badon me.

Also if you do a search on youtube on BMW in fixing an ignition coil call you should be able to find something

Thanks Paul, your post helped... Mine was throwing a cylinder 5 misfire and I changed all the spark plugs while there but the ignition coil on cylinder 5 had a tear on the outside rubber area. Would this have caused the misfire? In any event, I changed the coil and now it runs smooth.. Thanks again.

I wish changing my plugs and coil fixed my issue.
Same problem started yesterday for me on my 2008 x5 3.0. p0306 error. I replaced cylinder 6's ignition coil and had no luck. I also replaced all 6 spark plugs and had no luck. Now after all this work I get the following codes p0300, p0301, p0304, and p0306. (Could I have done something wrong?)

I spoke to a local mechanic and he told me that it was a vacuum leak and that it would cost me around 1200 to fix. I do trust him but I just cant see that being the issue. Does anyone have any advice on what I could try next before I bring it to the mechanic?
