Jerking when accelerating under full load

Hello everyone, I have a problem with my BMW 7 Series. When accelerating under full load, especially between 50 and 150 km/h, the car twitches and jerks, although the gearshift works normally. Does anyone have any idea what this could be due to or have had similar experiences? Many thanks in advance for your help!

(Translated from German)

A BMW 7 Series experiences jerking when accelerating under full load, particularly between 50 and 150 km/h. Possible causes include a clogged fuel filter, faulty fuel injectors, a malfunctioning MAF sensor, boost leaks, a problematic EGR valve, or a clogged DPF. Suggested solutions involve performing diagnostic checks for error codes, inspecting and potentially replacing the fuel filter, examining intake and boost hoses for leaks, and ensuring emission components like the EGR and DPF are functioning correctly. Consulting a BMW specialist is recommended if the issue persists.

Your BMW 7 Series diesel jerking under full acceleration between 50-150 km/h is likely due to common diesel engine issues such as a clogged fuel filter, faulty fuel injectors, malfunctioning MAF sensor, boost leaks, a problematic EGR valve, or a clogged DPF. It's advisable to perform diagnostic checks for error codes, inspect and replace the fuel filter if needed, examine intake and boost hoses for leaks, and ensure emission components like the EGR and DPF are functioning correctly. If unsure, consulting a BMW specialist is highly recommended. Let me know if this resolves the issue or if you need further assistance.
