I suspect this is quite normal for your engine. I have a '93 400E which does exactly the same thing. The owner's manual even says that as long as the pressure is at least .3 bar at idle, and rapidly comes up to 3 bar when under load, this is within normal limits. On mine, in the summer, pressure is a little under 3 bar when running at 55 mph on level ground and about 1800 rpm, but pegs the needle when I apply even a little throttle.
