P0015 on MINI
Exhaust Camshaft Position Timing - Over-Retarded (Bank 1)
P0015 on MINI vehicles indicates exhaust camshaft position timing - over-retarded (bank 1). Au7o has documented this code across 2 MINI models — most commonly on Cooper, GP. This code means the exhaust camshaft on Bank 1 is timed more retarded (later) than the computer commanded. Engines with variable valve timing use a cam phaser, controlled by oil pressure and a solenoid, to advance or retard camshaft position for better power, economy, and emissions. When the computer commands a position but the actual exhaust cam stays too far retarded, it sets P0015. This usually points to an oil-flow or phaser problem and can cause rough idle, reduced power, and poor fuel economy. Typical repair costs on MINI range from $200 to $900, depending on the specific model and root cause.
Common Causes of P0015
- •Low or dirty engine oil restricting phaser operation
- •Stuck or clogged variable valve timing (oil control) solenoid
- •Failed exhaust camshaft phaser/actuator
- •Clogged oil control valve screen or oil passages
- •Stretched or worn timing chain
- •Wiring or connector fault at the VVT solenoid
- •Incorrect cam timing from prior service
- •Faulty PCM/ECM (rare)
P0015 on MINI by Model
MINI Cooper(1 issue)
- Valve Cover and VANOS Solenoid Oil Leaks2007-2016
The valve cover gasket on N12/N16/N18 engines hardens and leaks oil onto the exhaust manifold, creating a burning oil smell. VANOS solenoid seals also leak, causing oil to pool around the solenoids and potentially cause misfires.
MINI GP(1 issue)
- VANOS Solenoid Issues (N18/B48 Engines)2013-2023
The VANOS (variable valve timing) solenoids on both the N18 engine (GP2, 2013-2015) and B48 engine (GP3, 2020-2023) are susceptible to failure from oil contamination and varnish buildup. When the solenoids stick or fail, the ECU cannot properly control cam timing, resulting in rough idle, poor throttle response, and reduced performance. The high-output tuning of the GP engines makes them less tolerant of degraded VANOS performance compared to standard MINI models.

What does P0015 mean on MINI?▼
P0015 stands for "Exhaust Camshaft Position Timing - Over-Retarded (Bank 1)." This code means the exhaust camshaft on Bank 1 is timed more retarded (later) than the computer commanded. Engines with variable valve timing use a cam phaser, controlled by oil pressure and a solenoid, to advance or retard camshaft position for better power, economy, and emissions. When the computer commands a position but the actual exhaust cam stays too far retarded, it sets P0015. This usually points to an oil-flow or phaser problem and can cause rough idle, reduced power, and poor fuel economy. On MINI specifically, this code is documented across 2 models.
What causes P0015 on MINI vehicles?▼
Common causes on MINI: Low or dirty engine oil restricting phaser operation, Stuck or clogged variable valve timing (oil control) solenoid, Failed exhaust camshaft phaser/actuator, Clogged oil control valve screen or oil passages, Stretched or worn timing chain. Specific causes vary by model and year — see the per-model sections below.
