It's been almost 50000km now that i can't figure out the solution for my issue. I have 225000km done and (except the auto transmission jerky behaviour ) when idling at about 750rpm with P selected on the gear i feel sometimes a small shaking of my car (hesitation of my engine like there is a faulty injector) but just for a second and then back to normal. When i accelarate slowly from a standstill position and at between 1700rpm and 2500rpm there is a big shaking and hesitation like something is clogged and the engine can't breathe. After about 2500rpm it's normal again. I also believe that through that issue my auto transmission became jerky. The only thing i know is that i have 1 burnt glow plug and no other fault code through diagnosis but problem existed before glow plug went out.
MY thoughts are :
- worn torque converter
- swirl flap blocked
- dirty intale manifold
- start of a clogged dpf
- maf or map sensor dead
What else? Please any opinion on that would be appreciated..

 

What does the iDrive say about the km left on Diesel Particle Filter?
Have you cleaned the EGR valve yet? It's definitely due at that mileage.

 

I have cleaned the egr and intake manifold at 130000km. I also regenarate dpf at 180000km.
