Around 60 mph check injection lights up and after a while check emissions. The engine then goes into safety mode.
Fault codes DF569, DF001, DF121, DF098, DF066, DF149 also fault memory 312.
Garage clears fault but returns when next driven over 60 mph. Claims that the boost presure is to low. Any ideas.

engines got a misfire and going into safe mode to protect engine check all wiring for chaffing on injection system also check all connections from pump to injectors
