Not sure if you have thought about it lately, but the “smog” pollutants coming out of your BMW tail pipe are a tiny, tiny, fraction of what they were in the early 1980’s. In fact BMW and most cars have become so clean, that with our current technology, who knows if it even can get much cleaner. That’s until we all go MINI e, but we’ll save that for another post.

The emphasis these days is more about the gases, vs. the actual pollutants coming out of your BMW exhaust system. We are talking CO2 which used to be considered a harmless and inert gas. The same CO2 that is absorbed by plants. It’s still a harmless and inert gas, (in the presence of oxygen) that we exhale every time we breathe. Sorry. We do not want to stop breathing in or out, (not even to save the planet)!

So lucky for us, we have the notorious or fantastic, (depending upon your experience and/or political leanings) check engine light that will warn a driver when one or more of those terrible gases is possibly making it’s way out of your BMW’s tail pipe. That light comes on even if it “thinks” it might possibly sneak out of your exhaust. The system monitoring your BMW emissions is comprised of actuators, sensors, and control units that will put you on notice if your gases are out of whack! Just a few hundred items or so can turn that little light on. OMG!

OK. Let’s be honest. We all want to breathe, we love our BMW’s, but some days that check engine light can test the patience of our BMW clients. Just breathe.
