Understanding your car's warning lights could save you time, money and inconvenience as well as improve your safety.

Oil pressure

The oil pressure light normally comes on for a short time when you start the car. If it stays on or comes on while driving it can mean that your oil levels are low. Without enough oil to lubricate the engine, serious damage can result leading to costly repair bills. Check your oil level. If it is low, top up with the correct oil (check your Owner’s Manual or ask us), but don’t overfill. If the oil level is OK, the problem could be that the oil pump is not working correctly or even that the sensor is malfunctioning. Your local AutoPlus Autoexperts team can diagnose the problem.

 
Alternator light

If the alternator light comes on this means your battery is using more energy that it is receiving. This could be because the alternator is not working correctly and therefore not charging the battery properly or that the battery is no longer able to hold the charge (especially as the battery gets older). Whilst this won’t damage the car while driving, the next time you go to start the car you could find that you battery is flat. The team at your local AutoPlus Service Centre can test to identify whether the problem is the battery or the alternator. We can replace your battery or make the necessary repairs if the problem is the alternator.

Check engine light

The check engine light can come on for a number of reasons. It can be a warning of a critical problem or a minor issue. The only way to find out is to have the car properly assessed. AutoPlus Service Centres are equipped to investigate using our diagnostic equipment.

    
Brake trouble indicator

It is normal for this symbol to show when the hand brake is engaged. However, if it comes on at other times it may indicate a serious brake problem. You should stop the vehicle and have it checked as soon as possible as continued driving could be extremely dangerous.
