That may not be the correct diagram for your vehicle as you haven't stated what engine it has Petrol or diesel and engine model. Better still put your VIN up so we can see what you have. Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.

That's a C3 Picasso (no grand in the C3, that is C4 only) 1.6 16V 92 BHP engine - no DPF, and on this vintage there is no lambda sensor, and def no NOX sensor! If it's done lots of miles there might be wear in the cam chain that drives the second cam putting it out of whack.

that ok, but can it be fixed? by changing chain
