    Hi.

    While driving, power is periodically lost and fuel consumption increases.

    However, there are no errors.

    Does not smoke!

    Can you tell me what can cause this problem?

    Hi. Yesterday we did diagnostics via MANcats and found the following: when the car accelerates, the pressure drops to 4.8 bar on the low side. For comparison, on another MAN TGX EURO 6 car, the pressure was 5.5 bar during acceleration. Now we are thinking about what to do next(((
