Warning lights of the Peugeot 607: what each light means
In the Peugeot 607, the documented faults light up 5 warning lights on the dashboard. The most frequent: engine warning light (2 faults), oil warning light (1 fault) and DPF warning light (1 fault). Oil warning light calls for stopping as soon as possible.
Which warning lights the faults of the Peugeot 607 trigger
Red ones first, and those that call for stopping. Below each warning light, the documented faults that trigger it, with their pages.
Oil pressure warning light on
Urgency: As soon as possibleRedSymbol: oil can (an oil can with a drop)
The red oil-can warning light means the engine is not getting the oil pressure it needs. The cause may be a low oil level, a failing oil pump or a blocked oil circuit. With low pressure, parts such as the turbo, the bearings or the timing drive can wear out within minutes.
What to do: Stop the car as soon as it is safe and switch the engine off. Check the level with the dipstick and do not drive on if the light stays on: call a recovery truck.
1 documented fault that triggers it in the Peugeot 607
- Critical severity: Crankshaft breakage and spinning main bearing shells · TDV6 / SDV6 engine
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.
2 documented faults that trigger it in the Peugeot 607
- High severity: Turbo faults, somewhat more frequent on the sequential twin-turbo versions · 2.2 HDi engine
- Medium severity: Faulty ignition coils · 2.0 and 2.2 16v EW10/EW12 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.
1 documented fault that triggers it in the Peugeot 607
- High severity: DPF clogging with additive, especially on the 128-138 hp version · 2.2 HDi engine
ESP warning light on or flashing
Urgency: Garage soonYellow or amberSymbol: the silhouette of a car with curved skid marks (swerving lines) beneath it, or the letters ESP, in amber or orange
The ESP light belongs to the electronic stability control, the system that brakes wheels individually and reduces power when the car starts to skid. It flashes while the system is intervening; if it stays on steadily, it usually indicates a fault (often a sensor) or that ESP has been switched off with its button.
What to do: If it flashes in a bend or on a wet road, ease off: ESP is working. If it stays on, switch off and restart, check the ESP OFF button has not been pressed and, if it persists, ask a garage for a fault code read-out.

- Medium severity: Central screen and dashboard electronics faults · outside the 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 Peugeot 607?
Engine warning light: 2 documented faults, such as turbo faults, somewhat more frequent on the sequential twin-turbo versions. Oil warning light: 1 documented fault, such as crankshaft breakage and spinning main bearing shells. DPF warning light: 1 documented fault, such as DPF clogging with additive, especially on the 128-138 hp version.
Which warning light of the Peugeot 607 is the most serious?
Oil warning light: its urgency is “as soon as possible”. Stop the car as soon as it is safe and switch the engine off. Check the level with the dipstick and do not drive on if the light stays on: call a recovery truck.
A warning light has come on in the Peugeot 607: what should I do?
Find which warning light it is on this page and check its urgency. With oil warning light, stop as soon as possible somewhere safe. 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.
