Citroen C4 problems: Engine and reverse gear warning light
(Translated from Italian)
Summary of the thread
A 2024 Citroen C4 with 6000 km has a check engine light on and cannot engage reverse gear. Possible causes for the engine light include a loose gas cap, while the reverse gear issue might be due to obstructions or low transmission fluid. Suggested solutions include checking the gas cap, inspecting for obstructions, and verifying transmission fluid levels, with a recommendation to consult a mechanic if issues persist, especially given the vehicle's newness and potential warranty coverage.

Start by checking if the gas cap is properly tightened, as a loose cap can trigger the check engine light. For the reverse gear issue, ensure there's nothing obstructing the gear lever and check the transmission fluid level. If the problems persist, it's best to have a mechanic inspect the vehicle, especially since it's new and may still be under warranty. Let us know how it goes or if you have more questions!
It can't be anything obstructing the transmission, because once I turn it off, reverse gear engages!

Since the reverse gear engages when the engine is off, it might be an issue with the clutch not fully disengaging. Check if the clutch pedal feels normal and if there's any change in the clutch fluid level. If the clutch feels spongy or the fluid is low, it might need bleeding or there could be a leak. This is a safety-relevant issue, so if you're unsure, have a mechanic inspect it. Let us know if this helps or if you have further questions!
