Loss of power between gear changes.
This problem has bugged me for years but appears to be bugging me more so may be getting worse.
When I change gear using the usual: foot off accelerator > depress clutch > change gear > release clutch > foot on accelerator. The car looses power massively on the "foot on accelerator" stage. It does pick back up but momentarily it feels like the car has stalled and the car can drop in speed. During the 1 to 2 change it is very noticeable because the car has little momentum.
I am at a loss as to what it might be, I don't get any engine codes on ISTA-D, INPA or Carly.
The car is a 2010 Mini One with 110k on clock which i have owned since 600 miles. It has been well maintained. I replaced both vanos solenoids at 80k with new BMW parts to solve erratic idling/stalling at idle.
Anyone had similar issues and any ideas?
