Warning Lights: What To Watch Out For
Warning lights on your dashboard are something no one wants to see. They usually mean that something bad and expensive is happening under your bonnet. Here are the most important/common car warning lights you need to know.
Never ignore warning lights on your dash and contact MotorEasy to arrange a diagnosis and repair. If you've got a warranty, even better, it's possible that the problem causing the light to come on is covered, saving you a large repair bill.
If your garage has quoted for a repair, check it is fair by giving MotorEasy a call. Our engineers can look thorugh what is being charged and advise the best way to bring costs down.

How To Check Warning Lights In Your Car
Warning Light 1: Oil
This is a bad light to come on and you must stop the car immediately and get recovered to your nearest workshop.
It's usually due to a noticeable increase in oil consumption and you should always check your levels regularly or for oil dripping when parked.
This could mean engine oil leaks. The solution depends on where the leak is; when new gaskets or seals are required then this is a reasonably simple garage job.
However, increased oil consumption and noticeable blue smoke from the exhaust, could mean a worn engine which is burning oil. A garage may need to fit new valve guide seals, or more seriously new pistons and rings, or even a new engine.

Warning Light 2: Airbag
Why is this one serious? Because it suggests that the airbag may not go off in the event of an accident. It's an instant MOT failure as well. This could be a simple sensor failure but it's essential that you get it checked out by MotorEasy.
Warning Light 3: Engine
If the engine or ECU (electronic control unit) warning light comes on it's likely that the engine is suffering from a lack of power or making a strange sound.
If not it could just be a minor sensor failure. Either way you will have to stop driving and contact MotorEasy to get the problem diagnosed.

Warning Light 4: Brakes
Another potential serious failure. It may be and indicator of seriously worn brake pads or some other fault with the system. There could be a leak in the brake fluid system itself. Make sure you head to MotorEasy for a diagnosis.
Warning Light 5: Power Steering
If this light comes on then it's likely that until you get the problem fixed your power steering will be disabled which could make driving harder.
There could be a leak in the hydraulic system, or a sensor fault within the electronic power steering system. This can sometimes be fixed by turning the car on and off again, but if it reilluminates then there is definitely a problem.
Warning Light 6: DPF Filter
Here's an increasingly common warning signal related to the Diesel Particulate Filter, which could be blocked by soot and is often accompanied by smoke from the exhaust.
This could be an expensive problem, but it could just need a regeneration. Either way you should consult MotorEasy.

Warning Light 7: Coolant
This comes on when your engine has sensed that it's getting too hot and is at risk of damage from overheating.
There could be leaks from hoses, maybe even the radiator and could lead to overheating. Best to stop driving, check the levels, top up with water to get you to where you need to be and speak to MotorEasy.

Warning Light 8: Battery
This light comes on when battery levels are dropping rapidly. In most cases the battery is due for replacement. Especially if your car is sluggish and the headlights are dim or go out when starting.
The battery may be flat and in need of a charge. Batteries have a lot to do these days, but usually the warning sign is just that.
It's not too serious, but you shouldn't ignore it and you do need to contact MotorEasy to get the battery checked. Always keep a pair of jump leads in your car in case the worst happens.
Warning Light 9: Tyre Pressure
This light comes on when the pressure in your tyres is too low and could cause unsafe driving conditions.
Usually it can be caused by a leak or slow puncture. It's best to stop driving until you have identified which tyre is the problem.
Remember both over and underinflation can cause premature tread wear and possible tyre failure.
