Half CEL light Still on please help
Half check engine light came on. Checked code P0303 (misfire cylinder 3) hoping/thinking spark plugs. Plugs look a little warn, so I changed all 4 (NGK iridium). Erased code with reader, started it up, cluster is still showing half CEL. Checked reader throwing no codes. Drove it around for 30 minutes checked OBD reader still no codes but light is still on.... My questions and concerns are
Do I have to reset the CEL light on cluster/dash manually? (I thought reader does that when you erase the code) Any other problems with P0303 I should be concerned with? Maybe the problem isn't fixed. How long will it take to throw a new code? Please help.. Any information from Cel light to p0303 misfire is welcome! Knowledge is power!! |

Are you talking about the half engine symbol that shows up in the tach display? If so, that is the reduced power symbol, not CEL. If that is what it is, you won't get codes via the OBD. You can drill down to get some codes, but usually they aren't very helpful unless you have access to MINI software to read all the codes and pull other info.

There is a code, but your reader can't see it. You'll need to get to a dealer, or to a good independent mechanic who has one of the MINI-specific (or BMW-specific) readers.

Hey everyone thank you for all your replies.
I Drove it to work (50mil) this morning and by the time i got to work the indication was gone... Stopped and started it up again 2-3 times to make sure it was gone. The indication did not pop back up. Checked BC options engine check said "OK" Hopefully it was just a matter of driving it around for the computer to reset/acknowledge the status..... i dont know i'll drive it home and see if the light comes back on later but i will double check with a dealer aswell. Thanks everyone! |
Keep us posted if anything else pops up. Mileage?
