Post by Roman »

Hello, i need some advice, before the inspection i had a diagnostics test done on my car Citroën C4 Grand Picasso 1,6HDI 2010. And it was a "WOW" 9 codes. Where to start from with the fixing i have no idea. I almost know what the codes mean but i dont know how to fix them. So the codes are:
P0490
P1495
P0483
P0409
P0100
P1461
P0489
D208
P1712

Is the engine warning actually on? What issues are you having? You need to delete all the codes and see which come back.

No warning lights, all of the codes could be deleted only one P0490 could not be deleted. I have no idea if they are back by now as i dont have the diagnostic tools myself but they did not come after deleting them and a little ride. The car is juddering on slow speed and on taking off. And it is using more diesel than it should.

P0490 is pointing to the EGR valve, not uncommon for them to be clogged up.

Ok, most of the codes are solved, the wires were bad in the fuse box whitch is next to the battery, the juddering is gone after hard reset(pushed accelerator in the floor until it reached 3rd gear) the EGR code still there, ill change it for a new one and see what happens.
