Very confused. And next week I am going on a 4 day road trip with the M5, this time I plan to reinstall the oem air filters instead of running those BMCs. Will report back if any differences are made. Also hope I can get the mid-cycle oil change done this week.

So you suspect your BMC filters?
I wonder how many F10M5'ers run the BMC filters? (removing the Charcoal filters of course). |
Wow, this is from quite a while ago. Yes, I did think it was the BMC filters but eventually, I didn't take them out and use the oem filters for that particular road trip back in summer time. It was all okay, no more warning signals since then.
In the past, when I used a pre-oiled air filter (K&N, aFe), usually I'd wipe it down with a auto shop paper towel before install them. I kind skip that on the BMC. Maybe that could be a cause, I can't be 100%.
