The control module detected the fault condition "The injector is not injecting enough or poor cylinder compression" for the No. 2 cylinder. Documented for the Delphi DCM 3.5 injection ECU (DW10C 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected that the Correction of injector flow rate cylinder 2 is jammed or locked. Documented for the Siemens SID 803 injection ECU (DW10BTED4 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
