Jerky acceleration E320 om642
Hi there new here
i am having this annoying problem with my E320 om642 and can’t seem to figure out the problem. It’s got a jerky acceleration when flooring it, it starts around 2500rpm. Had a scanner on it and the only code is P1103 maf sensor. A month ago I replaced the turbo actuator because it was bad. After I replaced it the car was running fantastic. But now the actuator isn’t moving, I am confused if the actuator already is bad again or, I need to replace maf sensor. I figured maybe the reason actuator wasn’t moving anymore was because of the maf sensor but I have no idea. I also tried the swirl flap delete with no luck. Because someone described almost exact my problems and it worked for him.
I have replaced air filters and fuel filter.
hope someone can guide me towards a solution

The om642 is a very sensitive and prissy engine when it comes to sensor readings. You may need to reset the maf and mean values in your scanners adaptation menu same for the air filters. I have found it best to do that every time you replace anything intake and turbo and or exhaust related.
You can also test the actuator somewhere in those menus and I do not recommend the swirl flap bypass just let the engine be. I’m at 285k miles and no issues
