Customer Advice - Diesel Engines

As part of the Diesel MOT test you may be asked questions about your vehicle's maintenance history, for example, has the timing belt been replaced recently?

Why is this information important?

The check has been designed to make sure, as far as possible, that no damage occurs to the engine whilst undergoing a diesel emissions test.

The tester has to satisfy himself that the engine is in a fit condition to test. If the tester thinks that the emissions test may damage your vehicle, he may refuse to test it.

How is the emissions test performed?

After checking the oil temperature to ensure the engine is warm, the MOT tester will accelerate the engine from idle until the governor cuts in a maximum of 6 times. Your engine will not be held at full speed for any length of time.

If your engine has been properly maintained, the test should not cause any damage to your engine.
