How MOT tests are done in

When your Porsche needs booking in for a MOT test, finding a reliable garage is important.

MOT stations should always be approved by VOSA and display the logo made up of 3 blue triangles, and the garage should also have a MOT cost sign stating the highest price of the test.

You can often view your MOT taking place by the registered tester in , though the majority of people drop off their KIA car in the designated bay and pick it up from the garage later once any repairs have been carried out and the certificate for the MOT has been issued.

Presenters will be provided with a paper copy, however electronic records are also held in a central computer database.

Lost or damaged certificates can be replaced at any test centre.

Should you need to tax your car, if doing it in person, the MOT certificate will need to be presented.

road wheel and tyre checks

Tyres will be checked in order to ensure they are the correct structure and tyre, including assessment of the aspect ratio, which if between 80% and 82% is sufficient, in order to ensure that wheels on the same axle match. The type of tyre structure will also be looked at to assess whether they are radial-ply, bias belted or cross ply.

Radial-ply tyres can be constructed from fabric or steel. Tyre sizes must also be printed on the side of the tyre, and usually includes the load index, ply rating and speed symbol.

Tyres should have a depth of 1.6mm continuing around the tyre and covering the central three quarters of the tyre surface. In addition, tyres cannot have any tears or bulges or expose any cords as otherwise there is a possibility that it will not pass the MOT test unless tyres in question have been replaced.

Fuel system testing and emissions checks in

Systems for fuel and exhaust need to be checked to ensure there are no leaks and to assess whether systems are running efficiently. When the exhaust system is being examined, components such as catalyst converts will be checked, to look for any faulty parts or areas that have deteriorated from corrosion resulting from exposure to water. Exhausts with excessive corrosion are likely to fail the MOT criteria.

In addition to this, the amount of exhaust fumes can mean that your vehicle hasn't met the MOT requirements if lambda, hydrocarbon and carbon monoxide levels are too high. Damaged lambda or oxygen sensors can be responsible for damage to catalytic converters and emissions failures resulting from amounts of unburnt fuel passing through the exhaust pipe.
