2015 Citroën C4 Picasso 1.6 HDi
The engine struggles to start and a couple minutes later a warning message accompanied by a warning sound says there's an issue with the engine and a few seconds later the engine shutdown.
What I already replaced:
Fuel filter
Fuel rail pressure sensor
HP fuel pump regulator valve
I also sent the 4 injectors to test at a diesel systems company and the result of the test is that all coils on the 4 injectors are bad and non serviceable.
It's hard to believe that the coils go bad on the 4 injectors at the same time but, what do I know?
I'm also suspecting of the HP fuel pump.
Can somebody more knowledgeable than me be kind enough to share the knowledge with me?
Cheers,
Andre.
