New MOT inspection manual to be introduced in May to reflect testing service changes
The DVSA has confirmed the introduction of a new MOT inspection manual on May 20, 2018 and spark ignition engine emission testing on and after February 1, 2018.

The DVSA is to introduce its new MOT inspection manual for class 3, 4, 5 and 7 vehicles to reflect changes to the MOT test which will be introduced in May 2018.

The new manual, which must be used from May 20, features an updated layout and additional sections.

New defect categories will be introduced as part of the changes to the MOT testing service, categorising defects as either ‘dangerous’, ‘major’ or ‘minor’.

Minor defects must be identified, recorded and the vehicle owner should be advised to have the vehicle repaired –  the vehicle will still receive a VT20 pass certificate.

The exact method of inspection will only be recorded where there’s a specific need, for example, brake performance testing or emissions.

A new manual is also due to be produced for class 1 and 2 vehicles, but the test for these won’t be changing immediately.

Spark ignition emissions

The DVSA has also announced that the 19th edition of the in-service exhaust emission data will be published on February 1, 2018.

From February 1, 2018 until your exhaust gas analyser database is updated, any vehicle listed that doesn’t pass the basic emissions test, must be tested using the limits shown in the 19th edition.

These may vary from those in your current EGA database.

  1. Good afternoon,

    It appears that you have listed the current MOT Manual in your hyperlink.

    I may be wrong, but would ask that you please check this as it will cause confusion.

    The new manual is on the DVSA’s current Special Notice 01-18.
