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

Quick Answer
Moderata GravitàSicuro da guidare (a breve termine)Emissioni

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.

Costo di riparazione stimatoDa €40 a €1300+, varia in base al veicolo

Cosa significa P0015?

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.

P0015 è un codice diagnostico di guasto relativo a emissioni, classificato con gravità moderate. Quando la centralina (ECU) del tuo veicolo rileva questa condizione, memorizza P0015 e accende la spia motore.

Quali sono i sintomi di P0015?

Se il tuo veicolo ha attivato P0015, potresti notare uno o più di questi sintomi:

  • 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

Cosa causa P0015?

Ecco le cause più comuni di P0015, ordinate in base alla probabilità che siano la causa del problema:

altaLow or contaminated engine oil
altaFaulty exhaust camshaft VVT solenoid
mediaStretched timing chain or worn chain tensioner
mediaClogged oil passages to the exhaust cam phaser
bassaWorn exhaust camshaft phaser/actuator

È sicuro guidare con P0015?

In genere sì, per brevi tragitti. You can drive carefully to a workshop, but expect reduced performance and possible rough idling. Prolonged driving may increase engine wear.

Come si diagnostica P0015?

Segui questi passaggi per individuare la causa principale di 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. Use a scan tool to read exhaust camshaft position data. Compare the actual position to the target position - a persistent offset 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

Audi

P0015 su Audi A4

2008-2024

The 2.0 TFSI (EA888) engine uses an exhaust camshaft adjuster that can fail due to oil sludge or a worn actuator. Audi recommends oil changes at 15,000 km but 10,000 km intervals are safer for turbo engines. The cam adjuster is at the rear of the cylinder head.

Domande frequenti su 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.
