I own a 1999 540i w/ 83,000 miles; the check engine light came on, stayed on for a day then went off. 4-5 start ups/shutdowns it hasn't "re-lit"
At 76,000 miles the light went on and stayed on- diagnosis resulted in replacing the MAF sensor.
Do I need to to be concerned? Does this require another trip to the local de3aler?
