Mokka Cylinder Pressure Fluctuations

My 2017 Vauxhall Mokka diesel (22460 km) has cylinder pressure fluctuations, higher fuel consumption, and power loss. The check engine light is on. Spark plugs are fine, no intake manifold leaks. Could it be piston rings, a fuel injector, or a timing belt issue?

I had something similar with my Mokka. The check engine light kept popping up, and the fuel consumption was definitely up. Power felt a bit sluggish too. Did you notice any weird noises or rough idling?

No weird noises or rough idling, thankfully. Just the performance and fuel economy are down. What was the issue with yours in the end? Was it a big job to fix?

Mine didn't have any weird noises either. It turned out to be a consequential error caused by another fault. I'm not sure if it's the same with yours, but you should get it checked out at a workshop. They'll be able to diagnose it properly.

Sounds like I'm best off getting it looked at by a professional. It was a consequential error resulting from another error. The bill came to 0€.
