Those bloody catalytic converters again - Michael Scott
My cat has just failed - '95 BMW 735. The car in fact has 2 cats - 481 miles each. The non-franchised garage can do the job for me but says he can only get standard parts. Does anyone know a cheaper solution (other than leave it until it drops off).

Also the garage say that the part comes a complete unit - the old cats need to be "sawn off" and the new ones fitted using sleaves (not welds as it is stainless steel). Sounds a bit odd to me - is this correct?

Srry I meant £481 each not miles

Are you sure this age of car needs working cats to pass the mot?

My folks have a K reg 106 that is effectively not tested.

J plate on needs a cat. This is a '95, so no option.

I think someone recommended www.fuelparts.co.uk/ as a source of aftermarket cats?

Also try europarts www.europarts.com or 020 8956 5000

Yes, anything post 93 needs pussies

Michael,

Why do you think your cats have failed?

Re: Those bloody catalytic converters again - Michael Scott
The exhaust sounds like a bag of spanners - same noise as the when the cat failed on my Passat a few years ago. The noise is coming from the cat - sounds like whatever is inside has turned to lumps. Apart from the noise the car drives fine.

Fair enough Michael.

I may have been lucky but unless they've fallen apart internally I've not had one fail the MOT on any of the cars I look after. Just wanted to make sure you didn't just need the "how to get a marginal cat through the MOT" answer!

Maybe he has a little sand in his catylist?

I beg your pardon Alwyn. Let's hope I will as well if I get that far.
