N54 Strange rattle on start, goes away immediately
Can anyone help me diagnose this rattle that I get when I start my E92? It lasts barely a second. The car runs and drives amazing, just got it today. One owner and dealer maintained,
strange rattle on start - youtube Not talking about the wastegate and exhaust flap rattle that can be heard in the video. |

That sounds like lifter rattle. When was the last time oil was changed? My N52 makes this sound near the end of the oil change interval when I rev it, not on cold start though. Does the sound happen every time it's started, cold or hot? If there's no record of a recent oil change I'd try that first, ensuring the correct LL-01 oil is used. |

Carfax says last oil change was 4k miles ago, so I’ll start with that when I am back in town on friday. Thanks! |
