You talking about this VANOS part? Wouldn’t I have other issues besides the first I press the pedal after sitting? That’s the only time this is happening. |

ok. This is leading me to believe it is most likely the solenoids. They seem like they don't work properly until the engine reaches proper operating temps. Probably gunked up.

With that in mind, instead of putting it in to drive after the cold start rpm drop I waited about 1min longer and today I didn’t have the issue. Interesting 🤔

Found this https://f30.bimmerpost.com/forums/sh....php?t=1702690 So you were right. Gonna replace my intake Vanos actuator. $60 + 30mins to do. Plus BimmerLink is sick. Turned off that annoying ASD and I finally hear the turbo spool and my exhaust sounds like it’s in the rear like it should lol. Also keep valve open now 😁 |

Hey guys having the same issue here. Just wanted to confirm that replacing the vanos intake actuator resolved the "21A02D - Combustion Control: Idle irregular" fault code?
Was there any additional steps/programming required? |

So I don’t have a solution, but I’ve literally had 3 N55 X5’s that do the exact same thing. One E70 and Two F15’s.
IMHO, let this sleeping dog lie. If there’s an underlying issue, you’ll eventually get a code. Spending time and money chasing down an issue that’s simply a minor inconvenience isn’t worth it.
