Before you buy this car
From the generation guide
- Lift the car and check the rear axle carrier for rust. Rust that has eaten through means a repair of about 2,000 EUR (year not stated).
- Turn the key several times. Clicking with no start, or a steering lock that stays locked, means the electronic steering lock is failing.
- On the test drive, check for jerks when pulling away and on the 1-2 and 2-3 shifts. Ask for gearbox oil change records. A Mercedes scan tool (XENTRY) shows pressure deviations. Above 0.5 bar points to valve body wear.
From the gearbox guide
- 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.
- 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.
- 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).
- 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.
- 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.
- Ask a dealer whether bulletin LI27.20-P-055758 applies to the car's VIN, and whether it was done. Bad result: lock-up codes FC 2783 or FC 0741 still stored.
