: Engine codes....help

07-19-2012, 08:48 PM
2004 545i, with 168k. It has 3 codes: p12, 491, and 492. Service engine light is on, and sometimes I get the words" increased emissions", sometimes I don't. There is also this little triangle in the center of speedometer, not the DSC, no arrows around it, very small one. The car also misses a but, I would say about 10% while park, once you take off the car is a beast. I have owned 7, and 3 series, never did 5, wondering what kind of suggestions I can get. And I have a scanner that reads codes. NOT taking it to the stealership for sure.
