Latio Cylinder Pressure Fluctuation

My 2006 Nissan Latio with a diesel engine is showing cylinder pressure fluctuation. I'm seeing higher fuel consumption, reduced engine power, and the check engine light is on at 100860 km. I suspect this is a consequential error resulting from another error. Any ideas?

A 2006 Nissan Latio with a diesel engine is experiencing cylinder pressure fluctuation, leading to higher fuel consumption, reduced engine power, and an illuminated check engine light. The issue was suspected to be a consequential error from another problem. After considering potential causes like the turbocharger, head gasket, fuel injectors, intake manifold, and camshaft, the problem was identified as a faulty sensor giving false readings, which was resolved without cost.

I had similar symptoms in my Latio, though I didn't check cylinder pressures specifically. The check engine light and power loss are worrying. Did you check the turbocharger, head gasket, fuel injectors, intake manifold or camshaft?

Thanks for the quick response. I suspected the turbocharger first, but pressures seemed fine. You mention the head gasket, fuel injectors, intake manifold and camshaft - did you have to check all of those?

Well, I didn't check them all myself. After fiddling with the turbo, I took it to a workshop. Turned out to be something else entirely. With those symptoms, it's tough to pinpoint the exact cause without proper diagnostics.

Understood. I appreciate the input. Turns out it was a faulty sensor giving false readings, no cost to repair. Thanks again.
