A little late LOL, but spark plugs were the answer to the problem? I'm getting the exact same problem and bmw couldn't see any misfires with the mechanics machine. I told them that it's only when the jb4 is on that it does that. I have no usb cable but tried looking for codes on dash and it says that there aren't any codes

Without a usb cable you are most likely running out of date firmware.

+1

There have been a lot of recent changes so its best to get a USB cable and stay updated.

I'm having this same problem, did you find any luck in replacing the spark plugs?

I was hoping the code reading off of the dash would tell me which cylinder was misfiring so that i would only have to buy one spark plug. But since the code reading is returning nothing, I will have to buy all 6 plugs

thanks man!

I recently changed my chip setting and disabled the delete code setting, I replicated the issue and read the code. It says I have a misfire in cylinder 1.

bought a set of 6 bosch spark plugs and the spark plug tool. Going to replace them this weekend. wish me luck

The difference is that I changed my plugs about 2 months ago and did about 3K km on them. Cant be the plugs going bad this soon can it?!? :

If so, the Bosch plugs are total crap! :

I took the codes this morning from the dashboard but need to get to the office before telling what it is exactly... Cant seem to remember all those blinks-flash-blinks to know it on the spot :

Will keep you guys informed!

Check coils by swaping from good cylinder to bad. Sticky is in the forum just follow missfire thread.
