No, but he showed me the Workshop Manual page D:02:01 with the control pressure values, and then he started the cold engine. The meter showed very low pressure (I don`t want to say anything stupid, but I think it was 0.5 - 0.75 Bar, not sure if that`s possible at all?), while the lowest value on the Manual`s diagram is 1.5 Bar. Either way, the actual control pressure was lower than what the Workshop Manual mentions.
And then the guy pointed at `warm` control pressure values in the Manual (3.4-3.8 Bar) saying that he measured the same value after warm-up.
