On the 2025-2026 Opel Combo 1.5 BlueHDi (DV5R) diesel, on Combo diesels fitted with the 1.5 BlueHDi DV5R engine, the common-rail fuel distributor (high-pressure rail) cone may fail to maintain its circular shape, allowing the retaining nut to loosen. Fuel can then seep between the nut and the thread, creating fuel vapours. If diesel leaks onto the hot exhaust/turbo it can ignite, causing a fire in the engine compartment. This was recalled across 14 Stellantis models including the Opel Combo built July to October 2025. A related newer DV5 recall also covers a NOx sensor that may not be properly tightened.

Common Symptoms

  • Smell of diesel in the engine bay
  • Visible fuel leak around the fuel rail
  • Fuel vapours/fumes
  • Risk of engine-bay fire

How to Fix

Take the vehicle to an authorised dealer for the recall. Technicians inspect/replace the high-pressure fuel rail and ensure the rail cone/nut interface is correctly formed and torqued so fuel cannot escape. Owners of recent diesel Combos should check their VIN against the recall database and act on any leak smell of diesel immediately.
