2007 530i Engine Misfire

I have a 2007 530i 6-cylinder.
Situation. Driving home from work, stopped at red light, SES light came on and enigne began to vibrate. Stopped and did a quick check, did not see any visable issues in the engine and verified vibration was definitely engine (rotation) related. Finished trip home, noted engine ran rough at idle and low speeeds. At higher speed (>50mph) engine seemed to smooth out some.
Checked codes with a hand-held ODBII and have a P0300, P0304, P0305, & P0305pd. All of these are engine misfire codes.
Checked the electrical side first. Replaced all 6 plugs and 1 coil that seemed to be weak. Checked all 6 coils afterward and they are all firing. (Also I do not have an "Ignition System Failure" warning message on the display.
Checked codes again, same 4 codes in.
Review of forums and discussion with BMW mechanic friend. I think the issue must be in the air-intake. (Ruled out fuel system due to only affecting a couple cylinders and issue smoothing out at higher speeds.)
I disassembled the entire air-intake. Checked all hoses/tubing no apparent cracks / leaks. Cleaned the MAF sensor. When I got to the DISA valve I ran into a possible issue.
The DISA on this engine is a solenoid operated flapper valve. I am unsure when it should be open or shut. When i pulled it out, it was open. I tried manually moving the flapper, it would not move at all. I am not sure if I can move it with out energizing it.
My questions are:
- What is the failed (de-energized) position of the DISA?
- How can I test the DISA outside of the engine? (Looking on the forums all testing of the DISA I find relates to the older, vacuum bellows type.)
- What other items should I check?

Thank you,
Micklen

After replacing the spark plugs and one coil, did you reset the codes?
Replace all coils. If one or two have gone bad, others are not that far behind.

If the DISA flapper is not moving freely, then it's fine.

Thanks for the feedback PCY.
Yes, I cleared the codes when I changed the plugs and coil. Plus after I removed and replaced the air intake.
Understand about the coils. Just trying to find the fault before I put all new components into it.
To verify all the cylinders were getting fire, I disconnected each coil, one at a time, while the engine was running. They all cut out (noticeable change in RPM & vibration) and pick back up once reconnected.
So now I'm ruling out the DISA, unless someone has a way to bench test it.
I did find a leak from the piston cover gasket. A small amount of oil on the left side, near cylinder 1. I ordered a gasket for it, not sure how this could affect firing of the cylinders.

'piston cover gasket'? I think you mean valve cover gasket. Small leak from valve cover gasket shouldn't cause problems with engine running properly.

Check your valve cover grommets n bolts that can also be your problem

Did you find the solution? In fact, there are two DISA valves attached to intake manifold.

Up & Running

Thank you everyone for your help! And sorry for the delay in wrapping this up.
I finally had a weekend to dig deeper into the engine.
On the air intake side, I removed the entire assembly and did not see any issues. Both the upper and lower DISA valves seemed to be fine. I removed all items to gain access to the valve cover and inspected each hose, electrical connection, etc. along the way. Again, nothing unusual or obviously broken. Then I got to the valve cover and found the "little leak" was much larger than I could see beforehand. (I was quite surprised that I had no oil marks on the drive way with as big of a leak it was. The "Underfloor Coating" did a great job hiding the leak.)
In removing the valve cover, I found two broken bolts beside each other. I removed the pieces, replaced the gaskets and all the bolts. After re-assembly, I cleared all the codes and fired it up. No more codes, no more miss-fire. Much happier me
Thanks again, and if anyone does happen to come across a test for the electronic DISA's, please share it!

Ignition coil on #6 cylinder is probably the cause.
Swap that 'suspect coil' with any other coil and see if the error 'moves' ...


If it was my car, I'd replace all 6 ignition coils and move on with life.

I drove to work, went out to lunch I don't see any misfire now. It happened yesterday and warning come on started idling rough etc. So now it's going to be hard to pin point.

Thanks

I would stick to OEM ignition coils.
