1) When actuating the IFI/DFI accelerator pedal position sensor > 50% the intake line resonance flap opens.
2) If EGR was recirculated previously, a waiting time of 50 seconds must be observed, after that, the values can be checked.
3) Except at maximum no-load engine rpm.
4) MSA 25.1 only.
12) Time Guide operation no. and/or SMS job no.
