Dear C3 owners,
Im chasing 1.4 HDI 16v. low power issues. When engine is cold - everything is fine, but after getting warm its losing power, gets down on power in the low rev range. Already checked/changed turbo actuator vacuum pipes. Im getting these faults...(see in the picture).
Question is - what fault codes means ?
P0129 Engine Speed Signal - Excess engine speed.
P1168 Diesel High Pressure Control Circuit - Circuit different, can't check by regulator
P0500 Vehicle Speed Received by CAN - Incorrect
1.4 HDI 16v. engine power issues

Hello
You have temporary codes, clear them (intermittent).
What is the code that is missing from the bottom for the screen, the injector fault?

Well. i don't know, my mechanic done scan with lexia and these faults showed up. After he cleared the faults, car feels ok - whenever engine is cold or warm everything is ok, power and boost feels like it should be, but after 100-200~ km. the issue starts all over again (i did not disconnected battery). Mechanic said to come back if check engine light shows up, otherwise he can't help me. Today im going to other mechanic to do leak test (just in case i missed something). This issue im chasing about 2 years....

The photo of the broken phone screen is not lexia.
You may get more information from lexia tool, but then again, scrolling the screen may give you more information too.
The codes are the key to diagnosing engine faults on the Citroen C3 HDi.
You can use lexia yourself and avoid going back to the mechanic each time and you don't need to wait for the 'check engine' light to use it yourself.
