2.2 Cat query?
« on: 24 September 2010, 19:18:56 »

About a year ago I fitted new downpipe with Cat. I was assured by everyone it was the right one for my 2.2, but management light remains on and still shows catalytic fault. recently spoke to dealer and motor factor who still insist 2.2 only has one cat showing on all their catalogues, not the experience of members of this forum.any help appreciated thank you. :(

 Thanks for reply, not sure what code was, management light stayed off for a period after fitting new downpipe then came on again, had it read again showed catalytic fault, that is why I'm considering replacing it if it's faulty

Ideally you need someone local with a reader to get the codes out of the ECU, that would help pinpoint the fault. There are a few Scot's members, hopefully one is close by and will pipe up (excuse the pun  :-[) and offer.

the pre-cat should have lamda sensors each side it and it was meant to be improve emissions.
also the cat in the centre section(under car) is only a half-cat.

You have a later non-genuine cat. To save money they fitted a single cat box with a lambda either side. It should work pretty much the same though.

Except that the cheap pattern cats rarely last longer than 2 years and are mega noisey plus they are known to cause fault codes.

ALL 2.2 petrol Omegas had 2 cats, of that there is no arguement  :y
