P0015 on Audi: Causes, Symptoms and Fix Cost
Quick Answer
Moderate SeveritySafe to drive (short-term)Audi
P0015 on a Audi 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.
Typical repair cost, all makes€40 - €1300

Audi A4
2008-2024The 2.0 TFSI (EA888) engine uses an exhaust camshaft adjuster that can fail due to oil sludge or a worn actuator. Oil condition is what keeps this adjuster working, so a stretched oil-change interval on a turbo engine is a common precursor. The cam adjuster is at the rear of the cylinder head.

How to diagnose P0015 on a Audi with OBD2
Follow these steps to pinpoint the root cause of P0015:
- Check engine oil level and quality. Top up or change if the oil is low, dark, or overdue. Use the manufacturer-specified viscosity grade
- 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
- Inspect and test the exhaust VVT solenoid. Measure coil resistance and check for clogged filter screens. Replace if faulty
- 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
- If other causes are ruled out, check timing chain alignment marks to verify chain stretch and inspect the exhaust cam phaser for wear
