What year?



He is refering to the rule. 1.6.3 mot emissions where it states.



(Different MOT testers can pass cars at their discretion please be aware some are complete and utter arseholes though)

Theres a lot of wrong info on this subject, mainly due to most MOT testers being wanks.



I'm training to be a MOT tester by the way lol.



Anyway, some info.



'The catalyst test is part of the MOT test for most spark ignition petrol engined passenger cars with four or more wheels first used on and after 1 August 1992'



Try this,



Vehicles Fitted with a different engine



Test according to which is older, engine or vehicle.


e.g. A 1995 car fitted with a 1991 engine (of whatever make), test to 1991 standards for emission purposes.



Note: Its down to the vehicle presenter


to prove engine age.



Since most starlets have had an engine swap its worth a shout :)

Also,



The vehicle will be tested according to its age from first use-The only exemption to this is if the vehicle owner can present to the tester at time of test a letter from the vehicle manufacturer stating that the particular engine as originally installed could not meet the equivalent British emission standards. If this is the case, then test to the next lower emission standard.


e.g. A 1995 car first used in Japan has a letter from the engine manufacturer stating that the particular engine (engine number to be stated) cannot meet Catalyst emission limits, then use the pre cat limits of CO 3.5%, HC )2000r pm.



Thats why you need a letter, according to your MOT tester.
