Known faults for Alfa Romeo Alfa Romeo 166
Our database tracks 3 specific mechanical faults and recurring failure patterns identified across UK MOT testing stations for this generation.
MOT Roadworthiness: Below 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 166
Known issues reported by owners and MOT testers.
- V6 Water Pump Plastic Impeller Failure and Overheating(Serious)
The factory water pump on the 24V Busso V6 engines (2.5, 3.0, and 3.2) features a composite plastic impeller. Over time and thermal cycles, the plastic becomes brittle, developing hairline cracks until it spins loosely on the metal drive shaft. Coolant circulation ceases, causing rapid engine overheating, blown head gaskets, or warped aluminium heads. Specialists fit metal-impeller pumps with cambelt services.
- Integrated Control System (ICS) and Heater Matrix Leaks(Moderate)
The dashboard centre console contains the Integrated Control System (ICS) screen governing climate, audio, and trip functions. Directly above the main electrical modules sits the cabin heater matrix. Ageing plastic matrix end tanks crack, leaking hot ethylene glycol coolant directly into the wiring looms and ECUs. This leads to flickering ICS displays, battery drain, and screen locking if code cards are missing.
- Front Upper and Lower Suspension Wishbone Bush Wear(Moderate)
The heavy executive saloon chassis and front-wheel drive place high loads on the double-wishbone front suspension. In the UK, road salt and potholed tarmac deteriorate the upper wishbone rubber bushes and lower arm rear compliance bushes. This generates loud squeaking over road bumps, steering vagueness, and rapid scrub on the inside shoulders of front tyres.
