ANNUAL TEST AND EMISSIONS

About features, and driver notifications on our MG-Rover Information Pages

On a vehicle which has passed all the required criteria, steering, brakes, electrics, then fails on the emissions, can be a problem and inconvenience. When this could have been checked before, With an emissions test prior to the mot, most garages, will offer to do a basic emissions test with no charge, or just a couple of quid.

Not all emissions tests are going to be successful, a short and direct drive to the testing station is one of them, engine may be hot, but wont be at its full working and operating temperature. Our own procedure before taking the pre-booked annual test, is to add some fuel additive.

A good long drive to achieve the vehicles fully operating and running temperatures, arriving at the test station a few minutes before our appointment, knowing the successful emissions test done a few days earlier, should not be too much of the slightest concern.

The emissions test is carried out after all vehicle checks have been completed, not as you arrive, this allows the engine to cool down and show that the car is in a genuine tip top condition, and not been thrashed just to get it through. We have had a fair share of advisories over the years, but no  fails, so the excellent emissions are one less of a worry.
