Research for this car

• Generation guide Mercedes Vito W447 (2014 on): known problems and buying guide

  Owners report a sound drivetrain, but check AdBlue warnings before you buy.

• Engine guide Mercedes OM651 2.1 diesel (C 220 CDI, E 250 CDI, Sprinter): problems, costs and what to check

  Durable when maintained, but check the cold start chain rattle, early injectors and the 2014 tensioner seal before you buy.

• Gearbox guide Mercedes 7G-Tronic (722.9) 7-speed automatic: problems, costs and what to check

  Buy only with fluid records and a clean full-system scan, and avoid any car that has run in limp mode or judders at a steady speed.

Known issues for this car

Before you buy this car

From the generation guide

1. AdBlue: with the engine running, check the dash for AdBlue and engine warnings, and check the AdBlue level. A scanner reads stored NOx sensor and dosing codes. Bad result: a warning, a stored code, or a van that refuses to start.
2. Recall campaigns: ask a Mercedes dealer to check open campaigns for the van's VIN, and ask for proof that recall work was done. Bad result: an open campaign.

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. 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.
3. Tensioner seal recall (VIN check). For cars built February to November 2014, ask a Mercedes dealer to check the VIN for the seal ring fix. Bad: no record of the fix.
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.

From the gearbox guide

1. Read the shift pressure data with XENTRY or an equal Mercedes scanner. Bad result: pressure deviations above 0.5 bar, or adaptation values above 30 percent. Those point to valve body wear.
2. Read the full gearbox fault memory with a full-system scanner. An engine-only OBD2 reader does not show it. Bad result: speed sensor codes P0717, P0718, P0722 or P0793, or any stored limp mode.
3. Test drive cold and warm, and pull away from a stop. Bad result: stuck in 2nd, slipping between 1st and 2nd, or limp mode at about 48 km/h (30 mph).
4. Hold a steady light throttle at about 60 km/h. Bad result: a shudder or hum. A scanner shows converter slip; 5 to 25 rpm is normal, and above about 80 rpm points to clutch wear.
5. Ask for the fluid invoices and check the fluid. Bad result: no change after about 80,000 km, dark brown or black fluid, a burnt smell, or a fluid other than the one for the build. A wrong fluid can cause code P0741. Red-amber is the correct colour.
