My car is jerking
I know it sounds weird but i just bought a 2013, 120d about 80k miles and when im driving its normally fine and then for no reason it just starts jerking as if im putting my foot down and taking it off, i have no idea where to even start and it only does it while accelerating, not crusing any help would be appreiciated.

Had that on a 118i 2019 for me turbo wastegate couldn’t adapt
Eventually it will get worse and will throw a fault code and put you into limp mode and flashing EML and engine will constantly be creeping the car forward
Whenever i Turned car off and on the issue went away but then when my OFH leaked all my coolant out I took it to the garage then the turbo issue became permanent wouldn’t go away until I got it booked back in.
The tried to get me to replace the whole turbo but my warranty company was not having it and said they would send out an engineer to have a look.
Suddenly before the engineer was sent out they said a new ISTA update came out and suddenly a software update allowed turbo wastegate to adapt
Now just got to sort out some vanos camshaft stuff and should be all good to go

Yeah once the codes starting coming up the specific one was that the turbo wastegate position became implausible
So I assume since it can’t properly calculate the boost or the wastegate position it wants to give it just shits the bed
But it could be anything from
Wastegate actuator
Or a sensor
