17958 - Charge Pressure: Control Deviation

[andy1max]

Had the loss of power problem on my golf tdi 110 recently only when going up a hill it goes into limp mode. Recently worked the actuator bar so it was moving freely but it still went into limp mode again after. Now i have the vag-com software i checked for fault codes and it came up with 17958 - Charge Pressure: Control Deviation.

Would it still go into limp mode just because the fault hasnt been cleared?? Ive cleared it now but just wondered.

Thanks Andy

If you clear the fault code, it does not fix the fault, you will have to do this to stop the fault code reappearing...
