My 2011 E91 330d (manual, if it makes any odds) seems to have started doing this bloody 2000rpm, partial throttle hesitation.
It's almost like a misfire.

No codes shown on Carly, glow plugs and module all replaced within the last year & run on VP Diesel from Shell.

I think from scouring N47 forums that it can either be the EGR sticking (not the hot side, but the mechanism sticking occasionally) or a vac line leak from degradation or split.

Has anyone else suffered this? I guess it's not a sensor / EGR / DPF issue because no codes are shown. I am wondering if a pipe/hose is split slightly as it's un-metered air...

Car drives fine, full boost, no odd noises, DPF regens fine.

Pah!

Pah!

I have the same issue on my '10 X5 (its obviously auto), it has few permanent Nox sensor codes but I don't think it is an issue!
Feels like there is a bad spot on TPS (sensor in gasoline cars) and it either goes to 40% throttle or goes to 10% - im thinking to check the PEDAL first??? Then do all the vacuum lines (does anyone knows where to order QUALITY clothbraided like OEM line besides dealer?

OP: What temperature your car is doing this?
I notice that this mostly to happen on cold/not yet warm engine!
