Another Hesitation Thread - F21 65 Plate 120d Msport

Post by managerxxx » Fri Aug 25, 2017 1:36 pm

Hi

I've had this car since new but I only clock up really low mileage (I'm currently around 3500miles!)

I detect very slight hesitation around 1700-2200 RPM intermittently under low acceleration which is more noticeable in 2rd and 3rd gears and sometimes this presents itself as a distinct 'stutter' for a second or so.

It's been to the dealer many times and they can't see anything on the logs or reproduce the issue. BMW have also looked at the car via the PUMA diagnostics platform to no avail. They've checked the EGR and I also have the latest software installed (at my cost) just in case the engine map was the issue.

Where do I go from here as it's ruining a great driving experience. Has anyone else had this and been able to resolve it?

Thanks

It's RWD. I've seen the posts re the transfer box no the XDrive variant....

Thanks

The lack of information share on this forum is horrendous.


Run turbo cleaner through it and see it it resolves anything

It could be sticking VTG vanes in the small turbo
