Warning lights of the Citroën Jumpy III: what each light means
In the Citroën Jumpy III, the documented faults light up 4 warning lights on the dashboard. The most frequent: engine warning light (3 faults), adBlue warning (1 fault) and DPF warning light (1 fault).
Which warning lights the faults of the Citroën Jumpy III trigger
Red ones first, and those that call for stopping. Below each warning light, the documented faults that trigger it, with their pages.
Engine fault warning light (check engine)
Urgency: Garage soonYellow or amberSymbol: outline of an engine seen from the side, in yellow or orange
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.
What to do: 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.
3 documented faults that trigger it in the Citroën Jumpy III
- Medium severity: AdBlue (SCR) tank and pump failure · 2.0 BlueHDi engine
- High severity: Injector and high-pressure pump wear · 2.0 BlueHDi engine
- Medium severity: EGR valve blocked by carbon deposits · 2.0 BlueHDi engine
AdBlue system warning
Urgency: Garage soonYellow or amberSymbol: AdBlue system warning in the instrument cluster, yellow or orange at first, usually accompanied by a text message and, later on, a countdown in kilometres
Diesels with selective catalytic reduction (SCR) use AdBlue to cut NOx emissions. A warning with a countdown ("engine will not restart in X km") indicates a low level or a fault in the AdBlue tank, pump, heater or injector. When the countdown reaches zero, the car will not start again.
What to do: If the tank is full and the warning persists, the problem lies with the system. Go to a garage before the countdown ends and keep your receipts in case the fault is covered by a manufacturer campaign.
1 documented fault that triggers it in the Citroën Jumpy III
- Medium severity: AdBlue (SCR) tank and pump failure · 2.0 BlueHDi engine
Particulate filter warning light (DPF)
Urgency: Garage soonYellow or amberSymbol: particulate filter symbol on the dashboard, normally amber; its design varies by manufacturer
On modern diesels it means the particulate filter is clogged with soot and has not been able to regenerate. It is common in cars used mostly for short town journeys, although it can also be caused by a sensor or by an injection or EGR fault.
What to do: If the handbook allows it, a 20-minute drive on a motorway at a steady speed can complete the regeneration. If the light stays on or you lose power, go to a garage.

- High severity: DPF clogging on short journeys · 2.0 BlueHDi engine
"Pollution control system faulty" message
Urgency: Garage soonYellow or amberSymbol: a text message on the dashboard ("anticontaminación defectuosa" or similar wording, in English "emissions system fault"), sometimes alongside an amber warning light
A common message on Peugeot, Citroën, DS and Opel cars from the Stellantis group. It appears when the ECU detects a fault in a component that controls emissions: the particulate filter, the EGR valve, the sensors, the AdBlue system or, on petrol engines, combustion problems.
What to do: It is not a specific fault but a generic warning. Have the car diagnosed with the right equipment to read the exact code before replacing any part.

Frequently asked questions
Which warning lights come on most in the Citroën Jumpy III?
Engine warning light: 3 documented faults, such as adBlue (SCR) tank and pump failure. AdBlue warning: 1 documented fault, such as adBlue (SCR) tank and pump failure. DPF warning light: 1 documented fault, such as DPF clogging on short journeys.
Which warning light of the Citroën Jumpy III is the most serious?
None of the warning lights with documented faults in the Citroën Jumpy III requires an immediate stop. The most serious fault that triggers one of them is injector and high-pressure pump wear (engine warning light), of high severity severity.
A warning light has come on in the Citroën Jumpy III: what should I do?
Find which warning light it is on this page and check its urgency. For the others, book an appointment at a garage and have them read the fault code with an OBD reader: it shows which system has failed.
