7 Reasons Why Cars Fail their Warrant of Fitness

If you want your car to be approved for its warrant of fitness so that you can drive it, it needs to pass what is known as an emissions test. Anyone who is fortunate enough to own a newer car will have no trouble with this. However, older cars will struggle with this test. The following are more reasons why your car may fail its warrant of fitness.

You Haven’t Put Additives in

If you didn’t put additives in your fuel when you refuelled it before the inspection, this will mean that there are still carbon deposits in the engine. Putting in additives cleans those deposits out, lowering emissions and helping air flow.

Unbalanced Tyres

While most people tend to get on top of this problem as soon as it rears its ugly head, some don’t. The odd person will even ignore it until it gets them into trouble. It will definitely get picked up during the inspection process. They will drive the vehicle on a dynamometer.

Your Vehicle’s failing to Function Properly

So, your vehicle is struggling to function in the fashion that it normally does. Don’t choose this as a time to take it in for the inspection for a warrant of fitness. Instead you should take it to your local mechanic to have proper repairs done.

The Check Engine Light is on

The check engine light is often forgotten by the vehicle’s owner. This could be due to the fact that often times it comes on for reasons that are pointless. A car that has this light on won’t necessarily have any serious issues. However, it will still result in an automatic fail. You will need to get it fixed. Take it to an emissions repair shop, as they will fix whatever problem it is.

You Drove There Straight Away

If you want to raise the likelihood of passing your warrant of fitness, drive it around for twenty minutes before getting there. The operating temperature of the catalytic converter, coolant and oil will be at ideal operating temperatures.

An Oil Change is Overdue

Have you driven your automobile for over 5000 miles without changing your oil? If you are planning on having an emission test done, it needs to be changed first. Oil that hasn’t been changed tends to have more hydrocarbons in it, which makes it hazardous. Change it and your vehicle will be more efficient, and you will also avoid failing your warrant of fitness for that particular reason.

You drove there in Wet Weather

Passing the Warrant of Fitness will be easier if you manage to avoid driving in wet weather before-hand. If the vehicle has wet tyres then it will be harder for them to be kept on a dynamo meter. A consistent speed is also harder to maintain. The amount of stress put on the engine and drive train torque will be excessive as a result.

Follow the above reasons and you will not fail your warrant of fitness test + you can expect top cash for cars while selling it in future.
