I've just had a sports cat fitted 100cell bcs and the engine light has come on after 30miles or so?

Can this be right? A sports cat throwing up the engine light? I've had the code read and it does say its the cat.

Bcs website does say this should not happen with thier cat but I have got the cat second hand.

I'm thinking of having the emissions read and see if the cat is doing its job, if do then maybe a lambda spacer is the only other option?

Thanks Jonny.

Tbh the car doesn't smell much more then with the slandered cat in terms of petrol smell, also it doesn't pop and bang any more the slandered cat also. I get better mpg and the turbo spools up a lot easer and quicker.

100 cell DS race cat does not turn the light on, many other 100cell cats will.
some 200 cells even turn the light on.

I used to think this as I've had a full DS exhaust system including the cat since July, using Bluefin maps which are designed to eliminate the light.
I've since changed to a Pumaspeed map and every 2-300 miles I'm getting the fault code for the O2 sensor, looks like I need a spacer for mine.

If it's turning the light on I'd get in touch with DS.

hi james its paul, not steph, when i ad mine over at pumaspeed tony asked were i,d got my spacer from, so i dont think they av them in mate.
Cheers mate, that's a shame, I know a place that makes custom exhausts between Leeds and Bradford so I may have another option, I just don't want to start getting under the car in the cold! Lol
