Citroën Jumpy III (2016–today)Warning lights and alertsUrgency: Garage soon

Engine fault warning light (check engine) in the Citroën Jumpy III: causes

In the Citroën Jumpy III, 3 documented faults may be the cause: AdBlue (SCR) tank and pump failure, injector and high-pressure pump wear and EGR valve blocked by carbon deposits, all on the 2.0 BlueHDi engine.[1][3][4]

What to do now

Garage soon

If it stays on steadily, you can drive gently to a garage and ask for a fault code read-out. If it flashes or you notice a loss of power, slow down and get to a garage as soon as possible.

What it means

The orange engine-shaped warning light comes on when the ECU detects a fault affecting combustion or emissions. If it flashes, it usually points to misfires that can damage the catalytic converter.

Engine and gearbox faults that cause it in the Jumpy III

Only those that affect the versions and years this car was fitted with. Below each title, how the symptom shows up in that fault.

How much it can cost

Depending on the cause, repair at an independent garage ranges from €200[4] (EGR valve blocked by carbon deposits) to €350[4] (EGR valve blocked by carbon deposits), including VAT. Before replacing parts, get a diagnosis: with a warning light on, the fault code usually points to the cause.

Most serious fault among the possible causes: High severity

Other common causes: engine warning light

In addition to the documented faults of the Citroën Jumpy III, these are the most common causes in any car according to the sources.

  • Faulty lambda sensor (oxygen sensor)[5][6]Common
  • Dirty or blocked EGR valve[5][7]Common
  • Deteriorated or blocked catalytic converter[5][8][9]Common
  • Spark plugs, coils or ignition leads in poor condition[5][10]Common
  • Faulty injectors[5]Possible
  • Blocked particulate filter[7]Possible

What to check first

  1. Note how the light behaves (steady or flashing; yellow, orange or red) and whether the car loses power, jerks, makes noises or gives off smoke. That decides whether you can carry on or must stop.[5][11]
  2. Check that the fuel filler cap is properly closed: a badly closed cap is one of the causes RACE cites and the easiest to rule out.[5]
  3. Have the codes read through the OBD port at a garage with a diagnostic machine: the error codes point to the part that is failing (sensor, EGR, injectors, ignition, catalytic converter).[5][9][10]
  4. Repair the cause and only then reset the light with the diagnostic machine. If you clear it without repairing, it will come back on.[5]
