I agree with the pump replacement. Converting to FSM display of data as follows:

With "D" selected
1) Measure modulation pressure => at stand still ------ 1.3
2) Measure working pressure => at stand still ---------6.7

3) Measure modulation pressure => at 65km/h ---------2.6
4) Measure working pressure => at 65km/h ------------4.8

With "R" selected
5) Measure working pressure => at stand still ---------- 8.2

units are in bar
