N62 - Delayed Throttle Response & Bogging at low revs

[OneFineDay]

Hi folks

Has anyone experienced the following with the N62 engine?

-Delayed throttle response

-Occasional bogging down in the lower rev range (1st and 1st to 2nd especially)

-Slight rev hang between gear changes/on clutch dip

-Slight consistent vibration at idle (very minor idle fluctuation, barely noticeable)



I have no fault codes nor check engine light. I have replaced all plugs during a recent service. The coils all altered engine note upon being individually removed, so seemingly ok.

Revs alter upon unplugging the MAF sensor.

My prime suspects are now Vanos solenoid seals and/or camshaft sensors so just wondering if the codeless symptoms are familiar with anyone, of if anyone has any possible suggestions to guide me with?


Vehicle is a 645ci 6spd manual for reference.

Thanks!
