Hi all, i have a G26 2022 4 Series 2.0 petrol that when statutory has intermittent running. The car has been in and out of BMW service for 2 years, with them saying there is no error codes.
The engine when idling will every so often, like misfire and shake. Has anyone else had this issue?

Its a shame that BMW service is so reliant on error codes

I would try running on on Shell V power for a couple of tanks . And give it an Italian tuneup ...
