Just weird

2008 M3E90 here. I was pulling out my driveway and suddenly "increase emission" popped and then the SES light too. Gas was 1/4 level and never had a warning light to fill up. I thought I would give it a day and this morning when I started it,it's same SES. So I decided to visit the dealer for diagnostics. On my way I stopped for gas and fill her up and then walaaaaaaa! It was gone. All systems checked okey. I'm so happy! Was it a glitch? if it was low fuel I should have gotten a warning light. Low fuel will trigger emission problems? Hope this thingy won't come back.

Sounds like your gas cap wasnt completely closed.

I've had this happen too. Unfortunately the "increased emissions" alert is a catch-all fault with lots of possible reasons. Some cheap easy fixes (like loose gas cap)...some a little more involved. I had mine into the dealer and they replaced the pre cat O2 sensor, cleared the fault, and it came back the next day. I then proceeded to fill the fuel tank with V-Power 93 octane ethanol free gas and have not seen the fault again. Now this is the only fuel I use. In my case it was simply bad gas
