Anyone know how I can escalate this further?

Keep a log of time versus air quality (perhaps you already have this), the more detailed the better.

Are you a BMW CCA member? I would send a letter to the editor of the Roundel with my log and detail the problem along with BMW's official response. If this really is a system-wide issue with G20 and perhaps others, I can't fathom BMW isn't aware of the brewing issue they need to deal with.

This weekend driving a 50 Jahre G80 M3 and the G87 M2 for about 30 minutes each, and I thought about your post a number of times during my drives lol with the assumption they have the same issue...

the issue is not that you drive with recirculation on for an extended period of time but rather as Pete posted - the car should be programmed to open up that flap on an interval basis to allow fresh air. This is not happening on my vehicle or any vehicle I have tested.

I tried to code it out with no luck. I tried almost every code setting available in expert mode on Bimmercode and then resorted to my backup.


I am going to do one more test at some point over the next couple days and take a 1 hour drive straight and see if the flap opens once (just to make sure I am not missing anything). If it doesn't I don't see how this can not be a large issue that BMW should be addressing. Especially when you have a car full of 5 passengers, a vehicle is getting no outside air? This is crazy stuff..


I also found other threads about this exact same topic:

Thank you! I am going to look more into this over the coming days!

4 people found dead inside a G20 BMW in Brazil after stopping for resting inside the car.

Asphyxia due to carbon monoxide poisoning is the main suspect for the cause of the deaths, according to the Police.

I’m just seeing this update on the post. I honestly wouldn’t rule it out that the issue I posted about could be the cause. The fresh air flap does not under any circumstances open in warm weather. Those conditions would have obviously been met given this happened in Brazil. If there was 4 passengers it would have compounded the time in which the oxygen was used up. If they were sleeping in the car the fresh air flap could have been the cause. Wow, just wow.

There are other articles that suggest it had to do with the A/C.

“The suspicion of poisoning by the odorless and highly toxic substance had already been raised in the investigation. During the investigationreports confirmed that the gas came out through the vehicle’s air conditioningwhich went through at least three tamperings”

I'm not sure what to think of this. Freaking me out a little. I may make sure to drive with window cracked in the summer...

Umm that story refers to CO poisoning not CO2.
CO is from exhaust gases, so somehow they got exhaust gases via the a/c? Sounds weird, but certainly nothing to do with what we are taking about here.

I understand that. What I am saying is that given how the system works it has to be almost impossible for CO to come in through the AC. The car wasn't in an enclosed space either, just a parking spot. The fresh air flap should be opening periodically to let in fresh air and oxygen but there is an engineering defect or software bug that does not allow that to happen. The fresh air flap remains closed regardless if you have it set to recirculation or fresh air mode. There were 4 passengers, so naturally they consumed the oxygen much quicker. If they were in that vehicle sleeping for 3/4 hours with the AC on the car never got outside oxygen..its like a submarine.

BMW will never acknowledge this issue but I know for a fact this is how it works.

The article states that Carbon Monoxide leaked into the cabin from a "perforation in the pipe between the engine and the dashboard."
