Engines: 1.4 / 1.6 16V (K4J / K4M) (Petrol) · 2.0 16V (F4R) (Petrol) · 1.5 dCi (K9K) (Diesel) · 1.9 dCi (F9Q) (Diesel) · 2.0 dCi (M9R) (Diesel)

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.

Connecting-rod bearing wear on the 1.5 dCiEngine (rod bearings)

Engine / equipment: 1.5 dCi (K9K), early series
Period mentioned: Approx. 2001–2006
Symptoms: Engine knocking, especially when cold; low oil pressure; at worst, engine failure.
Possible cause described: The connecting-rod bearings wear early, especially on cars driven a lot at low revs. It mainly affects models before 2006; Renault covered much of these repairs.
Check for the garage: Listen to the engine from cold, measure oil pressure and check the oil-change history. If it knocks, do not keep driving.
Cost cited in the source: No verified estimate; from replacing the bearings to replacing the engine.A rough figure from the original database, not an up-to-date quote.

1.5 dCi pump and injectors with Delphi systemInjection / turbo

Engine / equipment: 1.5 dCi (K9K) with early Delphi injection
Period mentioned: Approx. 2001–2011
Symptoms: Injection warning, jerking, rough idle, loss of power, smoke and sometimes a no-start.
Possible cause described: In the early years, the Delphi high-pressure pump can shed metal filings that contaminate the circuit and damage the injectors one after another.
Check for the garage: Read the codes (e.g. P0087, low rail pressure) and look for filings in the diesel filter. If the circuit is contaminated, replace pump, rail and injectors and clean the tank and lines.
Cost cited in the source: Approx. €1,800–3,500 (pump, four injectors, rail and circuit cleaning)A rough figure from the original database, not an up-to-date quote.

Engines: 1.5 dCi (K9K) (Diesel)

EGR valve sticking with deposits on the 1.5 dCiExhaust and emissions

Engine / equipment: 1.5 dCi (K9K) with an electric EGR valve
Period mentioned: No specific period published
Symptoms: Uneven idle, jerks when accelerating, lack of power or the engine going into limp mode, sometimes with the engine warning light on.
Possible cause described: Soot and oil deposits leave the EGR valve stiff, stuck closed or not closing fully. According to Pierburg it is rarely a fault of the valve itself: the oil comes through the crankcase breather, a turbo with worn bearings or a blocked oil return, late oil changes or too high a level, and many short trips, above all in winter.
Check for the garage: At the workshop: read the codes with diagnostic equipment (EOBD P0400 to P0404 or P0172; Renault DF077, DF084 or DF241), test the valve electrically and its opening with the engine warm, and find where the oil comes from (breather, turbo, level). Pierburg advises against cleaning it, as it can be damaged: it is replaced if faulty, and an engine ECU update sometimes solves it.
Cost cited in the source: No verified estimate; ask the workshop for a quote for the EGR valve.A rough figure from the original database, not an up-to-date quote.

Engines: 1.5 dCi (K9K) (Diesel)

Applies if: Only if the injection pump is a Delphi (it says so on the pump): depending on the version, the 1.5 dCi has Delphi or Siemens/Continental.

Delphi injection on the 1.5 dCi: air in the fuel, metal swarf, regulator or injectorsInyección

Engine / equipment: 1.5 dCi (K9K) with Delphi common-rail injection
Period mentioned: No specific period published
Symptoms: Hard to start or will not start, stalls, loses power or jerks; sometimes air bubbles show in the clear fuel pipe.
Possible cause described: The usual faults of the K9K's Delphi system are air getting into the low-pressure circuit, metal swarf from the pump contaminating the whole system, the pump's inlet metering valve (IMV), injectors with too much return flow and the rail pressure sensor.
Check for the garage: At the workshop, in this order: look for air and leaks in the low-pressure circuit and prime it; check the fuel filter bowl for metal swarf (if there is any, the whole injection system is replaced); measure the rail pressure, the IMV regulator's resistance (4.8–5.8 Ω) and each injector's return flow (25 ml at most in the test). A new injector's code must be written into the ECU.
Cost cited in the source: No verified estimate; it varies widely, from a filter or the regulator to the whole injection system.A rough figure from the original database, not an up-to-date quote.

Seized injectors and stretched chain on the 2.0 dCi (M9R)Timing / injection

Engine / equipment: 2.0 dCi (M9R) diesel with timing chain
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.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.
