Should not affect once warmed up. So the symptoms also aren't there on warmer climates so maybe that is why there was no recall just on "customer complaint basis"

Just thinking out loud my car has the resonator deleted by previous owner with just two separate straight pipes. Would this cause a misfire due to loss of exhaust scavenging?

IVM or why my engine runs sluggish??? N62 applies to ALL cars with it. E53/e65/e60/e63/e64/e66 | BMW LOGIC7

Mine isn't sluggish either, but I generally don't drive off until after it's done it's idle-dance. Then it's smooth as butter.

So you replaced the IVM? It's cheap enough and easy enough to swap it seems.

I haven't yet. My indy said to replace it once it starts throwing codes and the dance lasts longer or doesn't stop. I may just change it earlier anyway. Said he sees plenty of N62 cars with bad IVMs.

Susbcribed. Curious about this. Where is the IVM in our cars anyway?

Yep, keep us updated. Had planned on replacing my IVM as well preventatively as it is not too expensive.

Slick... if I recall it's in the fuse box under the hood on the passenger side.
