How to diagnose and fix P0015: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
MINI Cooper · 2007–2016
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.
Common Symptoms
- Burning oil smell
- Oil on exhaust manifold
- Visible oil leak from valve cover
- Check engine light
- Rough idle
How to Fix
Replace valve cover gasket (the cover and gasket are one unit on these engines) and VANOS solenoid O-rings. Clean oil residue from exhaust manifold.

Hyundai Santa Fe · 2007–2019
The Continuous Variable Valve Timing (CVVT) actuator and its associated oil control valve (OCV) on the Santa Fe's Theta II engine can fail, causing rough idle, poor fuel economy, and check engine lights. The OCV gets clogged with sludge from extended oil change intervals, and the CVVT actuator's internal components wear out. This issue can also trigger timing-related fault codes and affect emissions.
Common Symptoms
- Check engine light
- Rough idle
- Poor fuel economy
- Rattling noise on startup
- Hesitation on acceleration
How to Fix
Replace the CVVT actuator (camshaft phaser) and the oil control valve. Clean the oil passages feeding the VVT system. Switch to a high-quality full synthetic oil and maintain strict oil change intervals (5,000 miles or less). In some cases, cleaning the OCV with throttle body cleaner can restore function temporarily, but replacement is the permanent fix.

BMW M5 · 2006–2010
The S85 engine uses high-pressure VANOS (Variable Valve Timing) pump to supply necessary hydraulic pressure. The high-pressure VANOS lines were improperly routed without adequate bends to attach to VANOS pump, causing premature line failure and oil leaks. When VANOS line fails and leaks, it can starve VANOS pump of pressure, causing pump failure and sending metal debris throughout engine. This can escalate to CATASTROPHIC engine damage requiring complete engine replacement ($32,000). BMW settled class action lawsuit regarding VANOS failures and agreed to cover repairs for owners who reported issues before settlement cutoff date. M5Board warns: DO NOT ignore VANOS line leaks - this can destroy entire engine within weeks.
Common Symptoms
- Rough idling and unstable idle speed
- Reduced power output and poor acceleration
- Poor fuel economy
- Rattling or grinding noise from engine bay at startup
- Oil leaks visible near front of engine (VANOS area)
- Check engine light with VANOS-related fault codes
How to Fix
Replace high-pressure VANOS line with updated design that includes proper bend radius ($3,000 parts + labor). Replace VANOS high-pressure pump if showing signs of wear or contamination. DrVanos offers fully rebuilt S85 VANOS pumps ($1,800 + $400 core deposit) - M5Post gold standard for rebuilds. This repair is BEST performed simultaneously with rod bearing replacement to save on overlapping labor costs ($2,000-$4,000 savings). WARNING: DO NOT ignore VANOS line leaks - metal debris from failed pump circulates through entire lubrication system and can destroy engine. If catastrophic failure: engine replacement required ($32,000).

Frequently asked questions
What does P0015 mean?
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.
What are the most common causes of P0015?
The most common causes of P0015 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0015?
Repair costs for P0015 range from $100 to $32,000, depending on the vehicle and root cause.
Which vehicles are affected by P0015?
Au7o has documented P0015 across 6 vehicle models from 3 manufacturers: BMW, Hyundai, MINI.
