    hello, maybe someone else had this problem: MAN TGX EURO 6 (2017), it has no power at all, I changed the pressure sensor, air flow meter, changed both turbos, it has no error code.

    Any fault codes from the diagnostics?
    Have you checked the turbo pressure while driving, does it screw up? Has anything been tampered with with the EDC?

    Pressure differential on DPF checked ?
    Valve clearance checked ?

    Shame on our efforts, someone from Romania asked a question and it evaporated.

    Sorry, I have not disappeared. I still haven't discovered what the problem is. I have replaced the valves, turbo..., sensors, EGR.... Today I finally fired it up, went for a walk and after 10 minutes it started knocking in the engine again. Will reopen😩

Topic summary

The discussion revolves around a MAN TGX Euro 6 (2017) experiencing significant power loss despite the replacement of several components, including the pressure sensor, air flow meter, and both turbos. The original poster reports no error codes and seeks advice on potential causes. Responses suggest checking for fault codes, turbo pressure during operation, EGR functionality, pressure differential on the DPF, and valve clearance. The author later updates that despite replacing multiple parts, the issue persists, with the engine knocking after a short drive.
