SBDJ Posted October 15, 2008 Share Posted October 15, 2008 Hi all, I've got an MOT tomorrow - need to get it sorted urgently, as I'm providing the entertainment at Suprapod. When I bought my car it was decatted. It's MOT time now, and homer kindly lent me a 2nd cat to assist with this. I was going to chop the decat in two, weld a couple of flanges on, and bingo. What I didn't realise was that the UK spec has what looks like a second oxygen sensor (admittedly I haven't pulled it out yet, but searches say the UK has two). The cat Homer lent me doesn't have this, so this presents me with a problem. What do I do? Leaving it out is obviously going to affect emissions (otherwise why have it?), but if I don't get this MOT sorted, I'm stuffed!!

mr lover Posted October 15, 2008 Share Posted October 15, 2008 I didn't think the O2 sensor was in the second cat Quote Link to comment Share on other sites More sharing options...
SBDJ Posted October 15, 2008 Author Share Posted October 15, 2008 Just pulled it out, it's definately an oxygen sensor, and sits near the actual 2nd cat... Quote Link to comment Share on other sites More sharing options...
Marty Posted October 15, 2008 Share Posted October 15, 2008 I don't think the 2nd o2 sensor on the 2nd cat does a lot, you'll be ok with tieing it up, thats what i did with mine and it passed ok, its the 1st sensor which is the important one, which will be in its right place anyway Quote Link to comment Share on other sites More sharing options...
Homer Posted October 15, 2008 Share Posted October 15, 2008 Sorry mate, I had no idea the 2nd sensor was in the 2nd decat If you want to botch it into the cat feel free to do so, strip the shielding off if you need it's not important. Can always get it patched afterwards. Quote Link to comment Share on other sites More sharing options...
Fire148 Posted October 15, 2008 Share Posted October 15, 2008 I hear that some MOT garages equipment is not as sensitive as it should be ... if anyone knows any in the wiltshire area then now would be a good time to send a PM me thinks ???

Would make it easy to patch, but might be a bit of a mission to get sorted tomorrow given the sort of looks I got after seeing you when trying to find some exhaust flanges Quote Link to comment Share on other sites More sharing options...
SBDJ Posted October 15, 2008 Author Share Posted October 15, 2008 If anyone has a UK 1st cat or decat that I can borrow for a bit, it would make my life a *lot* easier Quote Link to comment Share on other sites More sharing options...
