Known issues for this car

Before you buy this car

From the engine guide

1. Timing chain (scanner needed). Start the engine cold and listen for a metallic rattle for 1-3 seconds. Ask a Mercedes dealer or a diesel specialist to read the cam phase offset (the timing gap between camshaft and crankshaft) with XENTRY, the Mercedes diagnostic tool. Check for codes P0016 and P0017. A plain OBD2 scanner may miss the offset. Bad: a rattle, a stored P0016 or P0017, or a large offset. A jumped chain can destroy the engine.
2. Injectors (scanner needed). Check for a warning light, rough running, judder and higher fuel use. Read the fault codes. Ask for the injector type and any replacement or service action invoice. Bad: a fault code, or piezo injectors with no service record.
3. Coolant (no scanner). Check the coolant level when the engine is cold, and check it again after a few weeks. Ask a dealer whether service action 1204P59A93 was done on the cylinder head coolant connection. Bad: a falling level or no record of the work.
4. Emissions software update (VIN check). Ask a Mercedes dealer to check the VIN for the emissions software update. Bad: no record of the update.
5. Oil and service history (no scanner). Ask for oil change records. Long gaps between oil changes, short trips and poor oil all speed up chain wear. Bad: long gaps or no records.
