Hello,

I just had my new 2021 M2 smog tested here in CA. It only has 15 miles. The guy said it failed and that I needed to go drive it for 100 miles because the computer is not ready?!? He said come back and he'll scan the computer before retesting to make sure that it is ready. Has anyone with experience in smog testing or BMW emissions engineering systems seen or heard of this?

This is a real thing, not sure which system it is (sensor calibration or actual smog) but something needs to sync for some mileage before it will pass the test.

Usually we avoid this with new cars entirely because they're exempt unless you're bringing them in from out of state (in which case this becomes entirely stupid).

I just received the car from an out of state purchase. I guess I'll just have to put on some miles. What a bunch of bull$h!;

I had to do a smog for CA on my 2021 and the guy checked the obd port prior to testing so I guess he was checking this issue. My car had only 20 miles at the time. It passed okay.

100 miles may or may not be enough. I think a post above pointed to things you can do to for "readiness". For what it is worth, I had to drive 800 miles for my 335d to be ready some time back. Diesels are allowed to have two sensors with incomplete readiness in Calif. Otherwise? I think only one sensor is allowed to have incomplete readiness. The process got the best of me so I beat the car hard for 10-12 miles on a crappy mountain road. Worked! Sold the car with a worn left-hand side motor mount. Not related ;-)

Many code readers will let you scan for sensor readiness. Worth it to get one regardless.

definitely not a bmw thing. all obd2 cars need to have their self checks complete to be considered "ready for testing." extremely common issue, "100 miles" is just a "that oughta cover it" distance.

Let us know if it passes after your drives to get the “system ready”.

Another shining example of CA nannie state stupidity

It's a new car for God's shake.

Passed after 230 mile road trip but what a PITA!!

California did not kill the Avro Arrow ;-)

I bought my 21 M2C from Kuni in portland/beaverton. The smog shop locally saw the paperwork on it being a brand new car and didn't even bother and just issued me a pass after making sure the exhaust was still stock.

California pay is quadruple in my field compared to where I used to work in Florida and it's only about 20% higher cost of living +10% state tax. Basically my wife and I come out way way ahead. -RN
