MoT test question (emissions)

hi the limit for a cat test on a 1994/5 on car is 0.200 c.o so i am guessing that your print out should show this? not 0.30 as you have shown? there are some ways around the prob as the engine speed is not able to be tested so if you M.O.T tester is a normal bloke and not an asshole he can test the car on tickover, this can get the emissions down to a pass {sometimes} or he can run the car well over th 3k max to bring the temp right up to stabilise the second cat then all should be fine?

Thanks Sly but this car is a '98 VVTi. My printout definetly says 0.30.

He told me to hold the car at about 3000rpm for the test.

We did hold the car at 3000rpm for a couple of mins immediately before the test to get the cat good and hot but it still didn't pass.

Jake,

 

My offer definitely falls into the category of less than ideal as I'm a little way from you but in case you don't sort this out another way the offer's there anyway...

 

Am planning to decat in the near future but could speed things up a bit and book in at Phoneix, Watford (if they're free) week after next as working in Watford for a couple days that week. If you cannot solve your problem another way my car would be there all day and you could nip up there, borrow the 1st cat and get your MOT done there.

 

Nick
