What are the MOT emissions for a Westfield/kit car?

This question does appear quite regularly on the forum, usually in the form of “my Westfield has just failed its MOT on emissions, what do I do now?”. It some cases it appears that an incorrect application of the testing rules has been applied, for example when a car registered on a ‘Q’ plate receives an emission fail, when it should not have had a measured emissions test at all. The ‘Q’ registration situation should be very straight forward as it is clearly established from the vehicle as presented. However, this is not always the case, MOT testers may need information supplied when a Westfield or any other kit car is presented for test, this should be provided by the vehicle presenter. The most obvious information is the V5c, but other information, specifically related to the age of the engine from manufacturer records etc. may also be needed. To help you decide what information you need to take to an MOT test and to indicate the test applicable, I have created the following flow chart, which in fact, is mostly in the MOT testing manual for emissions anyway. Hopefully you will be able to see from the flow chart what questions need to be answered in order to arrive at the correct emissions test.

Notes to be used with the flow chart:

 

Note 1: This fact takes precedence as the primary evidence of vehicle age is the registration. The MTS, MOT Testing System should show a Q plated car as registered before 1st Jan 1971. Additional notes in the testing manual state that for emissions purposes they are “treated as registered before 1st Aug 1975”.

 

Note 2: Based on an age related plate and date of first use of the kit car, the V5c may be required for proof.

 

Note 3: The presenter must provide the V5c for the tester in order that the correct limits may be used.

 

Note 4: In a case where there are no limits on the V5c and it does not state ‘visible smoke’ as an emissions test, it will be necessary to prove the age of the engine. This may be the V5c for the original donor vehicle or it could be a letter from a manufacturer or owners register etc. In some cases, particularly Ford, the engine date can be found online easily using the engine number. Where there is any doubt about the age of the engine then the lower of any emissions standards should be applied.

 

Note 5: There are Westfields listed in the DVSA In Service Emissions Standards for Road Vehicles document that is available online. This information is in the exhaust gas analyser database for use when carrying out an MOT emissions test. I believe these will be factory built cars only, and currently there are only two 1.8 Zetec engines, a 2.0 Cosworth and a 4.0L Rover V8 listed. To use the database record there must be an exact match, including the engine code, so if the presenter can’t supply an engine code and the tester cannot be sure of the engine code there is no exact match. Where there is any doubt about an exact match then the lower of any emissions standards should be applied.

Do you know what the 1.8 Zetec emission listed on the data base are?  Would be helpful to know...
