P0014 on Renault: How to Diagnose & Fix
"B" (Exhaust) Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)

P0014 on Renault by model: symptoms, diagnosis and fix
The first-generation 2.5-litre petrol Koleos uses the Renault 2TR engine, essentially the Nissan QR25DE. After roughly 100,000-150,000 km many owners experience excessive oil consumption (worn piston rings) and timing chain stretch, often signalled by a rattle on cold start. Delayed oil changes or incorrect oil viscosity accelerate wear of the chain tensioner and guides.
Common Symptoms
- Rattle on cold start
- High oil consumption / frequent top-ups
- Blue exhaust smoke
- Check engine light
- Loss of power
- Timing chain noise
How to Fix
Maintain strict oil-change intervals with the correct viscosity and monitor oil level between changes. Investigate any cold-start rattle promptly; a stretched chain requires replacement of the chain, tensioner and guides, and heavy oil burning may need a ring/top-end rebuild.

Frequently asked questions
What does P0014 mean on a Renault?
P0014 stands for ""B" (Exhaust) Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)." P0014 means the exhaust camshaft on bank 1 is timed too far advanced — the variable valve timing (VVT) system has moved the cam beyond the position the computer commanded, or it's stuck in an over-advanced position. The engine uses VVT to rotate the camshaft and optimize valve timing for power, economy, and emissions; the computer compares the commanded cam position to the actual reading from the cam sensor and flags this code when they don't agree. Common results are rough idle, reduced power, poor fuel economy, or a rattle at start-up. Oil flow and the VVT actuator are the usual suspects. On Renault it is documented across 1 model: Koleos.
What are the most common causes of P0014?
The most common causes of P0014 are: Low or dirty engine oil restricting VVT operation, Stuck or failed camshaft oil control valve (VVT solenoid), Clogged VVT solenoid screen or oil passages, Faulty camshaft phaser/actuator, Wiring or connector fault at the oil control valve, Stretched timing chain or jumped timing, Camshaft position sensor fault giving incorrect reading. The specific cause varies by vehicle.
How much does it cost to fix P0014 on a Renault?
Published repair estimates on Renault range from $600 to $3,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
