1. Engine and fuel system

High oil consumption (1.5 l petrol): May be due to worn piston rings.

Clogged injectors: Particularly relevant for used cars or when using low-quality fuel.

Timing chain problems: Over time, the chain can stretch, causing noise and engine malfunctions.

Diesel engines (1.4 l): Vulnerable to fuel quality, may have problems with injectors and particulate filters.

2. Transmission

Automatic transmission: Possible jerking when shifting gears due to contaminated oil or a faulty valve body.

Manual transmission: Clutch wear and bearing noise at mileage over 100–150 thousand km.

3. Suspension and steering

Rear beam silent blocks: Wear out over time, which leads to knocking and poor handling.

Shock absorbers: A weak point, especially on bad roads.

Steering rack: May knock at mileage of about 100 thousand km, requires adjustment or repair.

4. Electronics and electrical system

Problems with the control unit (ECU): Failures occur, especially on cars with high mileage.

ABS sensors: May fail over time, causing errors on the panel.

Wiring problems: Wear of insulation or corrosion of contacts, especially in areas of high humidity.

5. Body and interior

Body corrosion: Vulnerable areas are thresholds, wheel arches and the lower part of the doors.

Noise in the interior: Squeaks and noises appear over time due to wear of seals and plastic parts.

Recommendations for care and diagnostics

• Regular maintenance, including oil and filter changes.
• Inspection of the suspension every 20-30 thousand km, especially if the car is used on bad roads.
• Checking and cleaning electrical contacts, especially at the ground connection points.
• Use high-quality fuel and replace filters to prevent problems with the fuel system.
