Captur Hybrid Knock Sensor Issue

I had something similar with my Captur, though mine's petrol. Engine malfunction light and weird ignition timing. Did you check the sensor connections?

I wiggled the connections and used contact cleaner, but nothing changed. Was your warning light always on, and was the fuel consumption a lot worse?

The warning light was always on! Sounds like what I had. Get it checked at a workshop to pinpoint it. Could be the sensor or something more serious.

Booked a diagnostic check and it was the knock sensor! Defective cable like I thought. Cost 95€ to fix, but it's done now.
