Warning lights of the Opel Corsa E: what each light means
In the Opel Corsa E, the documented faults light up 5 warning lights on the dashboard. The most frequent: engine warning light (8 faults), oil warning light (1 fault) and overheating (1 fault). Oil warning light and overheating call for stopping as soon as possible.
Which warning lights the faults of the Opel Corsa E 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 Corsa E
- Critical severity: Timing chain stretch and tensioner failure · 1.3 Multijet engine
Overheating or temperature warning light
Urgency: As soon as possibleRedSymbol: thermometer over wavy lines (coolant)
The temperature needle climbs towards the red zone or the coolant warning light comes on. It usually points to a lack of coolant, a leak, or a failing thermostat or water pump. Driving on can warp the cylinder head or damage the gasket.
What to do: Stop as soon as you can and switch the engine off. Do not open the coolant reservoir cap while it is hot. If coolant is missing, do not set off again until you have found the leak.

- Medium severity: Coolant leak from the water pump or thermostat housing · 1.4 Turbo 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.

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 Corsa E
- High severity: Incomplete particulate filter regenerations and oil dilution · 1.3 Multijet engine
Seatbelt fault warning light or message
Urgency: Garage soon
The dashboard shows a warning related to the seatbelt or its pretensioner, separate from the generic "fasten your seatbelt" reminder. It may be caused by a fault in the sensor, the pyrotechnic pretensioner or the control unit that manages them.
What to do: Ask for the seatbelt and pretensioner system to be checked at a garage with the right diagnostic equipment, and check whether any manufacturer campaign is outstanding for your vehicle.
1 documented fault that triggers it in the Opel Corsa E
- Medium severity: Seatbelts that stick when pulled out or retracted (2019 campaign) · outside the engine
