P0019 on Mercedes-Benz: Causes, Symptoms and Fix Cost
Quick Answer
High SeverityNot safe to driveMercedes-Benz
P0019 on a Mercedes-Benz means the crankshaft and the exhaust camshaft on bank 2 are not in the correct rotational relationship. The code only appears on engines with two cylinder banks, V engines (V6, V8, V10, V12) and flat (boxer) engines, because bank 2 is the side that does not house cylinder 1 and an inline engine has a single cylinder head. Common causes include a stretched timing chain, a failed exhaust VVT solenoid on bank 2, a worn camshaft phaser, or oil flow problems.
Typical repair cost, all makes€60 - €6000
Connect any standard Bluetooth OBD2 adapter to your Mercedes-Benz and Skanyx tells you what P0019 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 in the W212 and W213 E-Class commonly sets P0019 due to camshaft adjuster magnet failure on bank 2. Mercedes parts are 250 to 400 EUR per side. The M278 V8 in higher trims has similar issues with more expensive bank 2 access. Always replace both bank adjusters together to avoid a return visit.

How to diagnose P0019 on a Mercedes-Benz with OBD2
Follow these steps to pinpoint the root cause of P0019:
- Check engine oil level and condition. V-engines share oil between banks, so low pressure or contamination affects both. Use only the manufacturer-specified viscosity and approval (BMW LL-04, VW 504.00/507.00, MB 229.5/229.51)
- Listen for cold-start rattle from the front of the engine. On V6 and V8, the rattle may originate from one bank specifically. A stethoscope helps localise it
- Monitor live cam phasing data on bank 2 exhaust 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 angle. Deviations over 5 to 10 degrees confirm a mechanical timing fault
- Test the bank 2 exhaust VVT solenoid. Resistance typically 6 to 13 ohms. Inspect the mesh screen for sludge debris. A clogged screen is a common quick fix
- If the solenoid and oil are good, suspect timing chain stretch or guide wear on bank 2. A workshop will need to remove the bank 2 valve cover or front cover for inspection
