Warning lights of the Opel Combo D: what each light means
In the Opel Combo D, the documented faults light up 3 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 Opel Combo D 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 Opel Combo D
- Critical severity: Timing chain stretch and tensioner failure · 1.3 Multijet 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 Opel Combo D
- High severity: Injector and high-pressure pump wear from contaminated fuel · 1.3 Multijet engine
- Medium severity: EGR valve blocked by soot · 1.3 Multijet 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 Opel Combo D
- High severity: Incomplete particulate filter regenerations and oil dilution · 1.3 Multijet engine
