Known faults for Alfa Romeo Alfa Romeo 156
Our database tracks 3 specific mechanical faults and recurring failure patterns identified across UK MOT testing stations for this generation.
MOT Roadworthiness: Average
This rating reflects historical MOT pass rates and recurring advisory wear patterns from official DVSA test logs. Note that roadworthiness does not verify outstanding finance, insurance write-offs, or stolen records.
Verify lender finance agreements, insurance write-offs, police stolen registers, and mileage rollback.
Common Problems: ALFA ROMEO 156
Known issues reported by owners and MOT testers.
- Cam Variator Rattle and Cam Belt Wear(Serious)
The Twin Spark engines on the 156 use a cam variator to adjust valve timing. When worn, it produces a distinctive diesel-like rattle on startup that lasts a few seconds. Alfa originally specified a 72,000-mile cam belt interval but reduced this to 36,000 miles from November 2006. A failed cam belt causes catastrophic engine damage.
- V6 Water Pump Failure(Serious)
The 2.5 and 3.2 litre Busso V6 engines on the 156 use a water pump with a plastic impeller that can crack over time. This causes coolant loss, overheating and potential engine damage. Alfa Workshop recommends replacing the water pump at the same time as the cam belt, typically every 60,000 miles on V6 models.
- Air Flow Meter Failure(Moderate)
The 156's air flow meter (MAF sensor) can fail, causing poor engine performance, hesitation, rough idle and increased fuel consumption. A faulty MAF sends incorrect airflow data to the ECU, resulting in incorrect fuelling. Replacement sensors cost around £120 and are a common fault on higher-mileage examples.
