2. Diagnosis & Intervention Protocol à Halifax
A failure (major fault) means that your pollution control line (Catalyst, FAP, Lambda Probe) is no longer doing its job, often because of deep clogging or a part out of service.
3. Management and Technical Solutions
Descaling with hydrogen, combined with a 'Special Technical Inspection' additive poured into the tank and good cleaning on the motorway (drive in 4th gear at 3500 rpm), allows the line to be cleaned.
4. Prevention and Maintenance in Halifax
Never present a cold vehicle for technical inspection! The catalyst needs to reach 400°C to work effectively. Drive dynamically before arriving at the center.
