P0015: "B" Camshaft Position - Timing Over-Retarded (Bank 1)

Quick Answer

Safe to drive (short-term)

P0015 indicates the exhaust camshaft on bank 1 is more retarded than the ECU commanded. The variable valve timing system for the exhaust cam is not adjusting properly, usually due to oil issues, a worn timing chain, or a failing VVT solenoid.

What does P0015 mean?

P0015 is a emissions-related diagnostic trouble code classified as moderate severity. When your vehicle's ECU detects this condition, it stores P0015 and illuminates the check engine light.

Where it is on the car

  1. Crankshaft sprocket and position sensor
  2. Timing chain or belt
  3. Camshaft sprockets with VVT phasers
  4. Camshaft position sensor
  5. VVT oil control solenoid

A timing fault like this is most often low or dirty oil or a sticky VVT solenoid. The phaser itself fails less often.

What are the symptoms of P0015?

If your vehicle has triggered P0015, you may notice one or more of these symptoms:

  • Check engine light on
  • Rough idle or engine hesitation
  • Reduced engine power, especially at higher RPM
  • Poor fuel economy
  • Engine rattling noise on startup
  • Possible stalling at idle

What causes P0015?

Here are the most common causes of P0015:

  • Low or contaminated engine oil

    : high

  • Faulty exhaust camshaft VVT solenoid

    : high

  • Stretched timing chain or worn chain tensioner

    : medium

  • Clogged oil passages to the exhaust cam phaser

    : medium

  • Worn exhaust camshaft phaser/actuator

    : low

Is it safe to drive with P0015?

Generally yes, for short-term driving. You can drive carefully to a workshop, but expect reduced performance and possible rough idling. Prolonged driving may increase engine wear.

How do you diagnose P0015?

Follow these steps to pinpoint the root cause of P0015:

  1. Check engine oil level and quality. Top up or change if the oil is low, dark, or overdue. Use the manufacturer-specified viscosity grade
  2. Read the actual and target exhaust camshaft position with manufacturer-level software (actual and target cam angles are not part of the standard OBD2 data set; a generic reader shows the code, freeze frame and fuel trims). A persistent offset between the two confirms the VVT system is not responding
  3. Inspect and test the exhaust VVT solenoid. Measure coil resistance and check for clogged filter screens. Replace if faulty
  4. Listen for chain rattle on cold starts. A brief rattle that stops after a few seconds indicates a worn chain tensioner. A persistent rattle suggests chain stretch
  5. If other causes are ruled out, check timing chain alignment marks to verify chain stretch and inspect the exhaust cam phaser for wear

How much does P0015 cost to fix?

Repair costs for P0015 vary depending on the root cause and your vehicle. Here are typical estimates:

Repair Parts Cost Labor Cost Total Estimate DIY Difficulty
Engine oil and filter change €20–€60 €20–€50 €40–€110 Easy
Replace exhaust VVT solenoid €30–€140 €50–€130 €80–€270 Moderate
Replace timing chain, tensioner, and guides €120–€400 €350–€900 €470–€1300 Professional
Replace exhaust camshaft phaser €90–€320 €200–€650 €290–€970 Professional

Prices estimated as of March 2026. Costs vary by region, vehicle, and shop.

P0015 on specific vehicles

P0015 behaves differently depending on your vehicle. Select your car below for model-specific causes and known issues:

P0015 on Audi
Volkswagen

Volkswagen Golf

2006-2024

The 1.4 TSI engines from 2006-2014 are particularly prone to timing chain issues causing P0015. Check the part number on the tensioner you remove before ordering a replacement. The EA888 2.0T can also develop this fault if oil changes are neglected.

Skoda

Skoda Octavia

2008-2024

Shares engines with VW Golf (1.4 TSI and 2.0 TSI). The same timing chain stretch issue affects early 1.4 TSI models. Skoda service intervals are often 15,000-30,000 km which can accelerate oil degradation in turbo engines.

P0015 on Suzuki

Suzuki Vitara · Suzuki Swift

Common questions about P0015

What does P0015 mean?
P0015 means the exhaust camshaft on bank 1 is staying in a more retarded position than the engine computer commanded. This affects engine efficiency, emissions, and performance because the exhaust valves are not opening and closing at the optimal time.
Is P0015 expensive to fix?
It depends on the cause. An oil change costs 40-110 EUR and solves many cases. A VVT solenoid replacement runs 80-270 EUR. If the timing chain is stretched, expect 470-1,300 EUR for chain, tensioner, and labour combined.
What is the difference between P0011 and P0015?
P0011 refers to the intake (A) camshaft being over-advanced, while P0015 refers to the exhaust (B) camshaft being over-retarded. Both indicate VVT system faults but on different camshafts. They can appear together if the timing chain is stretched.
Can low oil cause P0015?
Yes. The VVT system relies on oil pressure to adjust camshaft position. Low oil level, dirty oil, or incorrect oil viscosity can all prevent the exhaust camshaft from reaching its target position, directly triggering P0015.
