Title: BOB failed MOT
Post by jippy on Aug 2^nd, 2009, 1:05pm

My '97 cossie failed the MOT on emissions. The advice was to to replace both cats :-[
That 'll cost a lot, I'm afraid.
Can anything else be done? I dont want the car to be scrap yet!

Get a universal cat and weld it or pay someone to weld it..
Or get it from scrapyard and hope it's working.
That's how I did for my Granada and it didn't cost too much (50 euros)

Cats aren't expensive - got one for my old 24v for £70 last year. Fitting can be a pain though.

As already said though, you really need to diagnose it firt and get it on an OBD reader - that will tell you if it the cats (or just one) or the lambda sensors at fault.

As suggested above, get it correctly diagnosed first.

"The advice" was likely a guess
