My car was manufactured in May 1993, and has a catalytic converter as standard.
Usually therefore at each MOT its emissions are tested according to the post-92 more stringent requirements, for CO, NO, and Lambda.
However, every few years for some unknown reason the tester decides to use the previous standards, and only CO is tested, with a less exacting pass rate. This has happened twice in the past.

Yesterday it was again tested under the old regs, the print-out clearly stating "Non-catalyst". After I had got the pass certificate safely in my pocket I asked the tester, as a matter of interest, why he had used the non-cat test even though the car clearly has a cat and is post-92. He said it is nothing to do with him - he just types in the year, and the VOSA computer tells him what to test.
It is very odd - last year, at the same garage, the new-style system told him to do a cat test.

Anyone else had this experience, or know what is going on?

Your car falls into a very grey area where the fitment of cats fell between voluntary and compulsory and hence you can just about get away with having it tested under the old requirements. I had an RS1800 Fiesta at one time and that was a January 1993 car, although it had a cat it was quite legally tested under the old rules - which was a good job as it had a straight through replacement (non) cat pipe when the original cat failed.

Cliff is this was your Volvo then we have the same car and my MOTS always test to the post 92 regs and mine was done last month. Regards Peter

If the tester's menu is driven by the year/model then presumably it's possible for VOSA to change the menu for say a 93MY Volvo if they get it wrong first time or whatever.

I can understand a one-off mistake either by a tester or the Vosa system, and I could understand that through some error it might get permanently re-classified as non-cat even though 1993. But it is puzzling that it seems erratically to come up in either category - one year 1992, another yeat 1993, then back to 1992, then 1993.
It's not as if it was in a real grey area - eg manufactured 1992, but registered 1993. The DVLA records clearly say manufactured May 1993, and when the tester keyed in that date, it nonetheless told him to do a non-cat test.

If I could be sure this change would now be permanent I might consider removing the cat. But then probably next year it would revert again and fail for not having one.

Another curiousity of the MOT system is that I now know advisories are not followed up. Last year I was advised that the exhaust manifold shield was missing. It has never had one so I ignored it. This year there was no mention.

winter 92/93 was the time when fitting of cats became mandatory. Many vehicle manufacturers had a stock of non-cat cars and so complained to the government, which delayed the introduction of the law for a short while until stocks were cleared (i.e. made selling of non-cat equipped cars legal). Your car should be tested to non-cat standards. You will probably find that the tester tests it to cat standards and then only does a non-cat test if it fails the cat test! VOSA will not chop and change the data on the system.
I often take import cars for test (pre-Aug '95 don't require a cat) and the tester (who is a mate) always does a cat test. Only if they fail does he do a non-cat test - don't know why but that's what he always does. You may also find that right at the bottom of the front page of your new-style V5c form it states the allowable CO limit...

I was talking to my MoT tester this week and asked the question as to whether previous advisories were flagged up to him on line when a car was submitted for a test. His answer was a categoric NO. Interesting since advisories are definitely available on line for ordinary punters to see!

He did comment that many of the proposed enhancements envisaged for the new system have never been implemented. His view was that a fully integrated MoT testing station with automatic logging of brake and emissions was in reality a dream too far.

Interesting!
I was in his 'office' with him at the time when he was logging the car on, and could not remember if there had been any advisories on my Fiesta last year. Which is why I asked the question! His answer was undoubtably a NO. So the the next question be asked is how are the advisories are flagged up? Is the advisory information only available if the tester asks for it? And has this tester never found out that he can ask for it? He is a quite 'interested' individual and always willing to talk about related matters, and I am very surprised if he was wrong.


We also did talk about what happens if there is an appeal (not relevant to me , but for general interest), and he said that VOSA use an ordinary testing station not related to the one that issued the original disputed certificate. They allow the tester who conducted the orginal test to be present during the reassessment of the vehicle. On one occasion he reckoned the inspection and subsequent discussion lasted for several hours. I did ask him what happened to other tests scheduled to take place (since the time logging appears critical under the computerised system), and wheter the garage charged VOSA for occupancy of the test bay. But did not get a definitive answer.

We need a a practising MoT tester to answer the question. Altho I will try and ask the garage owner who is also a tester the same question next week.

I got an advisory a few years ago - "corroded inner rear wing". Found the corrosion, painted on some rust-primer, and gave it a nice thick coat of Hammerite. Next year, the car passed with no advisories, same tester, same garage!
