Investigate the pressure convector valve on the egr, egr closes at around 2,700pm so this would give a possible explanation to your symptoms. The actuator can get clogged with dirt and stick open affecting the pressure when the egr is active.

Also whilst checking, look at the vacuum pipes for perishing
