P0022 on Mercedes-Benz: Causes, Symptoms and Fix Cost
Quick Answer
Moderate SeveritySafe to drive (short-term)Mercedes-Benz
P0022 on a Mercedes-Benz means the intake camshaft on bank 2 is positioned more retarded than the ECU commanded it to be. The variable valve timing system on bank 2 cannot advance the camshaft to the target angle, typically due to a stuck VVT solenoid, low oil pressure, a stretched timing chain, or a worn cam phaser. The code only appears on engines with two cylinder banks: V6, V8, V10 and V12 engines and flat (boxer) engines.
Typical repair cost, all makes€60 - €6000
Connect any standard Bluetooth OBD2 adapter to your Mercedes-Benz and Skanyx tells you what P0022 means on that engine, whether it is safe to keep driving, and what the fix should cost. Free on iPhone and Android.

Mercedes E-Class
2005-2024The M276 V6 sets P0022 frequently due to bank 2 camshaft adjuster magnet failure or sticking. Mercedes Magnet Stellglieder are 250 to 400 EUR per side. Use only MB-approved 229.5 or 229.51 oil. The M278 V8 has similar issues. Plan for 400 to 600 EUR per side fully installed.

How to diagnose P0022 on a Mercedes-Benz with OBD2
Follow these steps to pinpoint the root cause of P0022:
- Check engine oil level and condition. Use only the manufacturer-specified oil approval. Low or contaminated oil is the most frequent cause of P0022 and the cheapest first step
- Monitor live cam phasing data on bank 2 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). Compare actual versus commanded intake cam angle. A persistent negative deviation confirms the camshaft is stuck retarded
- Locate the bank 2 intake VVT solenoid and remove it. Inspect the mesh filter screen for sludge debris, which restricts oil flow and prevents proper cam advance. Clean or replace
- Measure solenoid resistance with a multimeter (typically 6 to 13 ohms). Out-of-spec readings indicate a failed solenoid
- If the oil, screen, and solenoid all check out, suspect timing chain wear or a sticking cam phaser. A workshop will need to remove the bank 2 valve cover for direct inspection
