Why does my engine light sometimes go away after i turn the car off then back on?

The Check Engine Light is a signal from the car's engine computer that something is wrong in one or more of you electronic components that your vehicle has. A quick and simple process to try, is to safely get your vehicle off the road, turn off of the ignition and turn it back on again.  This will restart your vehicles computer which will reset you engine light. This is very similar to when your computer or mobile phone isn't working as it should, we simply turn it off and back on again. Should the engine light return immediately contact your mechanic and discuss how best to proceed. 

Whilst your engine light may reset, when the car has been turned off, this does not mean it won't return. Therefore it is always advisable to contact your mechanic to arrange a time to have a diagnostic scan carried out to check what the fault was as this will be stored in your engine computer.

How often should I service my car?

So, what’s the magic number? Well, most car manufacturers suggest every six months to a year or every 10,000kms, whichever comes first. But keep in mind, this is just for an average vehicle. Cars that perform more heavy duty tasks are advised to have more frequent services. Plus, if you drive an older car, it might be worth booking in a little earlier and keeping a close eye on your odometer. Good mechanical repairers should look at your car and individually diagnose it (just like if it were a person going to the doctor - everyone’s different!).
