Both DSC/4x4 message and the limp mode aren't appearing on same time.


After the ignition switch job, the DSC message appears every time, not regarding on my driving style. Usually i drive 5 10min and it appears. Maybe some sensor like the ABS one?
Of course the DSC off button doesn't work, so as the downhill one.

Does it means the car is in propulsion mode only now?


Haven't checked the nylon gear but saw a video about changing it. A way to check it without dismounting the thing?


I planned to do all the glow plugs + the module, but bit affraid of all the topics i see about snapping a plug in the hole. Don't know when the have been changed last time..
Where is the GP control module located? Found different diy, saying it's under the manifold, then in the relay box under the hood...


How hard is the fuel pump / filter job? I guess i'll have to be ready to have diesel splashing my face


EDIT: In addition to the glowplug codes i have 4521 and 4BB6
