Engine Weaknesses 3
The AEX timing belt must be replaced every 120,000 km or 5 years. Failure risks engine damage. Often neglected on the Arosa.
Symptoms: No warning signal — sudden engine stall on belt failure
On the 1.4 AEX, a corroded distributor rotor and deteriorated ignition leads are common failure causes. Corrosion causes sporadic misfires without a stable fault code.
Symptoms: Sporadic misfires, juddering especially in damp conditions, engine running rough when cold
The 1.4 8V AEX frequently suffers from worn valve stem seals causing oil consumption and blue smoke after cold starts. Typical wear from 120,000 km.
Symptoms: Blue smoke on cold start or after extended idling, oil consumption 0.3–0.5 l/1,000 km
Vehicle Weaknesses 3
As a budget car the Arosa is susceptible to corrosion on the sills, wheel arches, and underbody. Especially examples without cavity sealant rust early.
The suspension springs on the Arosa break at higher mileage more frequently than usual. A typical roadworthiness inspection defect.
The cable-operated window regulators in the Arosa are prone to wear. The cable snaps or the guide rail breaks.
