MOT Fail

[5harp3y]

i recently had to replace mine. £150 for both cat and lambda. fitting is a case of 6 bolts iirc

Mine had to have a new cat for its MOT, which is interesting as technically mine is old enough not to require one.

[towelie]

mines had two new cats bought by previous owners to make it pass even though it doesn't need one... think i'll try an get it changed to an eunos roadster on the certificate

Could be cat or it could be O2 sensor or temp sensor or any number of other things.
