MOTORE 1.5 BLUEHDI PSA: PROBLEMI PIÙ COMUNI, SOLUZIONI E CONSIGLI (2025)

✅ Overview 1.5 BlueHDi

The 1.5 BlueHDi engine (Peugeot, Citroën, Opel, DS) is a Euro 6 diesel that replaced the old 1.6 HDi. It is fitted to models such as the Peugeot 208, 308, 3008, Citroën C3, C4, Opel Astra, Grandland X, DS3, DS7 .

  • Displacement: 1,499 cc
  • Power: from 75 to 130 HP
  • Turbo: variable geometry
  • SCR system with AdBlue for NOx reduction

⏱️ When problems appear

The most frequent defects emerge:

  • after 70,000 – 100,000 km
  • with intense urban use and short journeys
  • in case of irregular maintenance
  • using low-quality diesel fuel

⚠️ Most common problems with the 1.5 BlueHDi

1) Clogged particulate filter (DPF/FAP)

The DPF clogs easily with city use. If it doesn't regenerate, the engine warning light appears and the vehicle goes into emergency mode.

  • Prevention: drive on extra-urban routes to promote regeneration
  • Avoid turning off the car during the regenerative cycle

2) AdBlue system problems

Defects in the AdBlue tank, pump, and injector are common, especially in winter. If they malfunction, the engine will not start.

  • Use only certified and unexpired AdBlue
  • Have regular checks at the workshop

3) Noisy/stretched timing chain

The 1.5 uses a chain instead of a belt. In some cases it stretches prematurely, causing rattling noises and error codes ( P0011 , P0012 ).

  • Solution: Preventive chain replacement in case of noise or errors recorded

4) Clogged EGR valve and manifolds

The EGR tends to get dirty with short travel, causing power loss and higher fuel consumption.

  • Tip: Consider cleaning every 50,000 km
