Common Problems & Weak Points

Issue	Typical Mileage	Repair Cost (Est.)	Severity
Water Pump Leak	~80,000 km	€200 – €400	Medium

Water Pump Leak

The most common failure point. The water pump seal fails, leaking pink coolant. If ignored, the engine overheats rapidly due to the small coolant volume.

Typical Mileage: 80,000 km

Cost: €200–400

Buyer's Inspection Checklist

Check for pink crusty coolant leaks around the belt area.
Listen for excessive timing chain rattle (though some noise is normal).
Check oil level (they tolerate low oil well, but better not to test it).
Test clutch bite point (city driving wear).
