Long story short, I bought my m235i recently and I can’t get these monitors to set (Catalyst Monitor, 02 Sensor Monitor, 02 Sensor Heater Monitor). I have driven 200 miles combined both freeway and city. On top of that, the sport gauges show maximum of 480 hp and 560 torque, from what I gathered online is that it’s tuned that’s why it shows more than a stock one. I have no way to contact old seller as I bought this car from an auction. It won’t pass smog without the monitors set. Is my M235i tuned? How can I get it reverted back to stock? TIA.

Right off the bat I think you should choose a different forum for this question.

Sure soundsike it is tuned. I'd probably move to a state without emissions testing. Barring that, you're maybe gonna be able to find someone to flash. Stock tune, but disabling those sensors means you're likely looking at further modifications that required sensors be disabled. Catless downpipes or similar

Lol I second the guy that said wrong forum... asking about a BMW in the non-BMW section. Sounds a lot like a tune though, I know when I tuned mine with MHD it changed the numbers in the sport display
