HI,
I have first dtcs 2078 diff pressure sensor plausibility error and car goes limp mode, no full power like brand-new.
Lately dtcs 2069 and 2070 appears but after erased they cleared.
Only 2070 appers after a short trip and car does not have power.

live date appers to be normal so sensors are good, no need to replace.

The ash contens is 6g and content of filter is around 13% so I think I still have dpf.

SMOKE TEST INTAKE, CHECK ALL RUBBER FITTINGS-
CHECK SMALL STEEL PIPE TO EGR( INSIDE CAN COLLAPSE)-
NOT SURE WHAT YEAR IT IS, BUT SOFTWARE BUG UP TO 12/2004 TO DO WITH COLD START IN ECU-
CHECK CONNECTIONS OF ALL PRESSURE AND TEMP SENSOR WITH CODE RELATED TO THEM-
