  The clutch and its actuator are the main risk. Check the gear changes first, then the cooling system and the oil level.

Known issues for this car

Before you buy this car

From the generation guide

1. Look for coolant loss. Check the radiator, expansion tank, water pump and hoses for leaks. A leak can mean a water pump or cylinder-head gasket job, which costs up to 1,500 EUR (Germany, year not stated).
2. Pull away and make several gear changes. Slow, late or jerky shifts, judder, a clutch that slips, a stiff pedal, or the three-bar warning mean a clutch or actuator job, about 400-800 EUR (Germany, year not stated). Ask for proof that the gearbox was re-learned after clutch work. That needs diagnostic equipment.
3. Check the oil level on the dipstick and look under the engine for oil. Ask for oil change records. Oil loss is common, and it can get the car refused at TÜV.
4. On an MHD car, listen for whistling, chirping or squealing from the drive belt when starting and driving. These are warning signs of a belt problem.
5. Look at the exhaust on a lift for rust, mostly on 0.8 CDI cars used for short trips. The catalytic converter and rear silencer are one part on earlier cars, so replacing them is expensive.
6. Give the VIN to a dealer and ask for open recalls. The heater shut-off valve fix (cars built 2010 to 2014) is free. The brake caliper bracket recall (cars built 28 February to 6 March 2012) corrects bolt torque.
