An update on this.
Replaced the EGR valve two weeks ago (major job, difficult accesses). Still have the problem
Replaced the pressure sensor this week (different garage). Still get the same problem. Booked in again for Monday.
Symptoms are at speed on motorway up steepish incline under load. Light comes on at 2800 - 3000 rpm in fifth gear when acellerator downed. Goes into limp home mode. Cleared by switching ignition off an on again.
