Koleos Rail Pressure Sensor Issue

I had something similar with my Koleos. Check the sensor and its wiring. It could be a loose connection or damaged wire. Is the sensor sending any signal at all?

Thanks! Were your symptoms the same? Did your Koleos also feel like it was choking? I want to be sure before I start replacing parts. How much did the repair cost?

Yes, almost identical symptoms: sluggish performance and stalling. Honestly, I'd take it to a workshop to get a proper diagnosis. It's probably the sensor, but it's best to be sure.

Thanks for sharing! I replaced the rail pressure sensor (240€). The engine runs perfectly now, like new. I appreciate the help!
