the seal in the cap must not be torn, deteriorated or missing (includes self-sealing flaps)

no other defect which could cause fuel to leak out

the fuel tank must be securely mounted.

Test of Exhaust system and Emissions

The exhaust system will fail the MOT if:

Part of the system missing or excessively deteriorated

Mounting are missing or damaged so that the exhaust system is insecure

There is a major leak

The system emits appreciably more noise than a similar vehicle fitted with a standard system in good condition.

Emissions

Diesel smoke emissions are checked by using a smoke meter.
