Known Issues 3
Timing belt replacement — interference engine
▸Preventive only — failure destroys engine
Belt not chain. Replace every 60k km. Used in Polo/Golf/Passat/Bora. Legendary engine otherwise.
Most important ALH maintenance. €250-500 at any Greek workshop. Do not skip — any Greek mechanic knows this engine.
Injection pump wear (very high mileage)
▸Rough idle, hard start at extreme mileage
Bosch injection pump lasts enormous mileage. Only concern on documented 300k+ km examples.
If buying 300k+ km ALH in Greece: pump inspection worthwhile. Most examples fine well beyond this.
Turbo wear at very high mileage
▸Boost loss, slight smoke
Turbo outlasts most engines. VNT actuator can stick. Otherwise very long-lived.
Low concern for typical Greek market. Only at extreme mileage.
