Around one-in-three vehicles will fail the annual MOT according to the Department for Transport.

Motorists can ensure a first time MOT pass and avoid non-required repairs by carrying out basic preparation before their MOT, claims a new report.

Mail order specialists, Car Parts Direct claim most vehicles that fail their MOT do so because the owners fail to carry out simple checks or procedures. They leave themselves at risk of having vehicle repairs carried that may not be required. The UK is one of the few countries in Europe where the person carrying out the MOT is also legally allowed to carry out repair work on the customer’s vehicle.

Mark Cornwall of Car Parts Direct said, “Something as simple as revving the engine before parking up for an MOT. Even adding a fuel cleaner is enough to help ensure a vehicle passes the MOT Emissions test – it’s things like this that motorists can overlook”

Mark Cornwall also claims some rogue mechanics see females as an easier target and are more likely to find additional work at MOT time. A survey carried out by the company found women are 11pc more likely to fail an MOT than their male counterpart.

Car Parts Direct recommends leaving an MOT check list on the passenger seat of the vehicle when going for an MOT. Using an MOT Station where vehicle repairs are not carried can increase your chances of passing first time.

Motorists are also advised to check the price of parts before being persuaded in to have an MOT failure repair carried out. Mark Cornwall said, “Some garages will offer a very low labour rate and then overcharge for supplying the parts to do the job – so it’s always worth shopping around or ask the garage if you can supply your own parts”.
