MOT Test: Which Components Need to Perform Properly to Pass?

If your car is 3 years old, then it is about time you visited a car garage for getting an MOT certificate. If it’s more than 3 years old, then you have to get an MOT certificate every year to make your car roadworthy.

MOT tests are performed by more than 20,000 car garages across the UK. You can get an MOT in Newport from Trade Price Tyres. They also have trained technicians who can check every component of your vehicle precisely and help you with the necessary repairs or replacements for it to pass the MOT test.

Some of the critical components that need to perform correctly include:

  1. Exhaust System

Your vehicle’s exhaust system is a combination of various parts like the exhaust manifold, catalytic converter, muffler, exhaust pipe, etc.

Simply speaking, the primary function of an exhaust system is to convert the harmful gases produced by an engine during combustion and to CO2 and water and eliminate them from the car.

Any fault in the exhaust system will lead to:

  • Lower fuel economy.
  • Smell of gas inside your car.
  • Burning smell from under the hood.
  • Noisy engine.
  • Lower power and acceleration.

A faulty exhaust system can also increase vehicle emissions that can cause you to fail the MOT test. Hence, look out for these symptoms and visit a car garage at the earliest to resolve them.

  1. Suspension System

Notice how you get a comfortable ride even when riding over bumpy roads. Well, it’s all thanks to the suspension system. The entire system is composed of shocks, struts, bearings, joints, springs, steering, wheels, etc.

Any fault in the suspension system can cause:

  • Your vehicle to pull to one side.
  • One side of your car to sit low.
  • Your vehicle to nose-dive when braking and lean back when accelerating.
  • Difficulty when steering.
  • A uncomfortable bumpy ride.

Be wary of these signs and get your vehicle diagnosed before it’s too late and you end up failing your car’s Mot Test Newport.

  1. Tyres

Next up are your car tyres which also have to be in proper condition for you to get MOT certified. Here, “proper condition” specifically denotes the tread depth.

Every new tyre will have a minimum tread depth of 7 to 8mm. With time, this depth lowers. To pass an MOT test, your tyres must have a minimum tread depth of 1.6 mm throughout their circumference and at the 3/4th circumferential width.

  • How To Check Tread Depth?

Take a 20p coin and insert it into the tread. If the outer rim of the coin is visible, then you will have to replace the tyre.

Do note that improper tread depth will not only cause you to fail the MOT test but also invite fines. You may end up paying £2,500 per tyre when driving with illegal tread depth. Further, you will also receive 3 penalty points per tyre.

The MOT test also checks other components of your vehicle excluding the above. Taking your car to a professional garage for a pre-MOT check can ensure that you pass the test.
