Dead... then Alive
2020 M240i Xdrive. Auto. 13k miles completely stock:
Took it out for a short drive. Comfort Mode. 4 stop signs. Country 65 mph. I then stopped at a Stop Light and it went dead! No Screen, no gauge lights: nothing. I first thought I had accidently had put it in ECO PRO but that was not the case. I hit the PARK button-foot on brake, and hit the START button: Nothing. I moved the shift lever, hit PARK again-foot on brake, hit the START button and it started. Anybody ever experience this ? Recommendations? Fob Battery? |

Back from Dealership Service dept. They ran Diagnostics and just as I suspected; Bad Muffler Bearing !!.... hate when that happens.
Actually I asked them to ensure that the Battery Gound Cable had a good connection also. Diagnostics showed nothing. |

"Bad muffler bearing"? It must need more relative bearing grease. Check Redline.

This joke is not funny to me. The butterfly valve in my exhaust (aka sport vs comfort) starting squealing like a banshee. So I put grease on the bearing and it went away for a few months. Then last week the valve was rattling like a loose heat shield, and I found the clip between the motor and valve was gone. So I think I do have a muffler bearing problem (the bearing on the exhaust valve anyway).
Better buy some blinker fluid. |
