Hi everyone I am hoping for more advice!
My Beat has failed its Mot due to very high CO emissions. It recorded more than 4% against a limit of 3.5% and I think that it should be able to achieve less than 1%.
The other things measured were close to what they should be so the tester is suggesting that the catalyst is defective.
It would be good to get peoples thoughts on this diagnosis – is there a particular issue with the Beat other than the cat that could give these symptoms? (It is worth noting that the ECU has just been rebuilt).
If I do need a new catalyst is there a source for one in the UK or has anyone successfully adapted one from another car – perhaps an early 1990’s Civic?
Thanks
Tom
