DPF BWB Polo 9N3 1.4 TDI: Jerky, Wave-like Power

Hello everyone,
I'm having a small problem with my Polo. It's experiencing slight jerking and a fluctuating power delivery, especially at speeds between 80 and 100 km/h.
Normally, I would have expected a higher LLM (Loan-to-Value ratio), but the loan-to-income ratio and the AGR (Annual Growth Rate) seem quite strange. The AGR appears to be generally very high and, in some cases, remains at 100.3%, seemingly independent of the repayment rate.

It would be very helpful if I could take a look at the file and hear your opinions.

Best regards, Sören.

Hi,

In the partial load range, if the EGR system is still functioning, the actual air mass is significantly higher than the target air mass, and the duty cycle for the EGR control is at its maximum.
I suspect your AGR valve is sticking, defective, or there are problems with its control (if pneumatic: leaks in the vacuum hose or the solenoid valve is stuck).

Best regards, Rainer.
