I have now managed to get the car through the MOT test. I have in fact not done anything to the car and I suspect that when it was tested originally it was not hot enough because the only thing I did to the car was drive it to another test station to get a second opinion and in this case it proved successful and saved a lot of money!

Thanks for your info, it has helped because it meant that I did not write off a very expensive piece of equipment without checking it out further, I wonder how many other people are misled by information given by garages that possibly do not understand these cats quite enough.

Thanks for your help,

Ian Martin

Thank you for letting me know how you got on, I am really pleased you've got through the test, you are not alone with this problem but you will with your answer help many others in the future.

May I suggest you use a fuel additive about every 6 months Slick 50 have a very good one (I use it myself) it's called Fuel System Treatment.

It really does make a difference, you will feel it almost straight away, it may also help to clean the Cat, and avoid another problem next year.

Well done, and Thanks.

Regards Bill
