Applies if: Only with the automatic electric parking brake.

Electric parking brake stuck or warning (Scénic II)Brakes

Engine / equipment: Automatic parking brake
Period mentioned: Approx. 2003–2009
Symptoms: Parking-brake warning on, brake that will not release or stays locked on both wheels, codes DF043 / DF049.
Possible cause described: Owner reports: failure of the electric motor or a relay in the brake unit, or a brake-pedal sensor sending a wrong reading.
Check for the garage: Read the codes with a diagnostic tool; if the brake stays locked, use the manual release (in the boot, next to the spare wheel). After the repair, relearn the slope sensor.
Cost cited in the source: No verified estimate; depends on whether the unit is repaired or replaced.A rough figure from the original database, not an up-to-date quote.

Applies if: Only with a key card (keyless start).

“Card not detected”: the car does not recognise the key cardElectrical and electronic systems

Engine / equipment: Hands-free card and cabin unit (UCH)
Period mentioned: Approx. 2003–2009
Symptoms: The cards stop opening or starting the car, hands-free and with the buttons, and “Card not detected” appears; sometimes it clears by itself after a few minutes.
Possible cause described: Owner reports: the cabin unit (UCH) stops recognising the cards’ code; described as common on the Scénic II and Mégane II.
Check for the garage: Try the other card and its battery; at the dealer or with a diagnostic tool, check the UCH and relearn both cards.
Cost cited in the source: No verified estimate; relearning the cards is usually a short garage job.A rough figure from the original database, not an up-to-date quote.

Period mentioned: Approx. 2005–2023
Symptoms: Chain noise at high mileage; loss of power and emissions warnings in town use; injectors that will not come out when removed.
Possible cause described: The chain can stretch at high mileage, the injectors can seize in the cylinder head and, with short trips, the particulate filter and EGR clog.
Check for the garage: Listen to the chain from cold, check injection and emissions codes, and before removing injectors have extraction tools ready. Keep oil changes up to date.
