🔧 Maintenance

Oil Change Interval:

Typically every 12,500 miles (20,000 km) or 1 year, whichever comes first (check manual for specific variant).

Timing Belt Replacement:

This engine likely uses a timing chain, which generally does not have a scheduled replacement interval but requires inspection. If it were a belt, it would be around 60,000-80,000 miles.

Engine Oil Type:

API CE/CF or ACEA B3/B4 specification, viscosity grade like 5W-40 or 10W-40 (consult manual for precise specification and Peugeot/Citroën approval codes like B71 2294 or B71 2296).

Coolant Type:

Glysantin G30 or similar OAT (Organic Acid Technology) type coolant, mixed 50/50 with distilled water (colour typically red/pink).

Brake Fluid Type:

DOT 4

Common Problems:

DPF (Diesel Particulate Filter) clogging (common on early diesels), EGR valve issues, turbocharger problems, suspension wear (especially bushings), electrical gremlins (e.g., multiplexing issues), potential for injector problems if fuel quality is poor.

Preventative Maintenance:

Regular DPF regeneration cycles, ensuring correct diesel fuel quality, timely replacement of air and fuel filters.
