So I bought the car last year (1.8T AUQ) without really understanding the implications of having a decat.
My MOT has run out and now I realise that without a friend to pass the MOT, I'm quite stuck. I've read around the forum and I see that without a visible cat it will fail immediately. Now I'm not exactly rolling in money so getting a genuine cat or branded exhaust system is not really an option. I've seen some 200 cell sports cats that are affordable, however they require welding, which I don't think comes cheap. I also think that even after having done all that, it will still fail on emissions becuase of how rich it is running.
At the moment it's just sitting in the driveway and each time I get a hint at what might be causing the rich condition I go and check, only for that not to be the problem. So far I've done; MAF, DIY Boost leak test (not sure how well I executed this), vacuum leak test (garage found ill-seated dipstick), DIY fuel injector test, checked the N80, changed the PCV piping and put the old airbox back on.
I'm thinking my options are to sell the car for extremely cheap and let someone who's better equipped to deal with the problems have it, OR get a sports cat welded, fix the rich condition and then take it to be MOT'd.
Got any advice guys?
