Which warning lights the faults of the Opel Combo C trigger
Red ones first, and those that call for stopping. Below each warning light, the documented faults that trigger it, with their pages.
Battery warning light on
Urgency: As soon as possibleRedSymbol: outline of a car battery
It is the red battery symbol on the dashboard. Even though it shows a battery, it usually warns of a charging system fault (alternator, belt, connections) rather than the battery itself: the battery stops recharging and the car runs on whatever energy it has left.
What to do: Switch off non-essential electrical consumers (air conditioning, radio), find a safe place to stop and call roadside assistance rather than trying to finish the journey.
1 documented fault that triggers it in the Opel Combo C
- Medium severity: Premature alternator wear · 1.7 CDTI engine
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 C
- 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.
