OBD Codes
P0380Injectors
Typical layout and location for the Injectors assembly.
Symptoms
- Hard starting in cold weather (below 5°C)
- White smoke on cold start for 30 seconds
- Flashing coil light or EML on dash
Root Cause
Carbon buildup around the tip of the glow plug effectively welds it into the cylinder head. Applying too much torque to remove it shears the threaded top off.
How To Fix
- Soak the glow plugs in penetrating oil for several days before attempting removal.
- Only attempt removal with the engine piping hot.
- If a plug snaps, specialist removal tools are required (£150-300 call-out fee).
- Standard replacement cost: £100-200

Other Faults on This Variant
Timing Chain Failure (K9K Engine)
SevereThe Renault/Nissan K9K 1.5 dCi engine in the Qashqai J10 is known for timing chain wear. Unlike a timing belt, there is no scheduled replacement — but chains stretch and tensioners fail.
DPF Blockage and Sensor Failure
ModerateDPF issues on the J10 Qashqai are common because many are used as school-run and short-trip vehicles — exactly the wrong driving profile for a diesel with a DPF.
Steering Column Clicking / Rack Failure
ModerateA clicking or clunking noise when turning the steering wheel at low speeds is extremely common. It usually stems from the steering column universal joint or the rack itself.
