Same as I posted on another thread a while back, after 6 and half years of ownership my little 1.4 failed emissions.
I wasted money trying everything to pass it, lambda, sparks, throttlebody (had a spare lying round), cat etc.... List goes on and still wouldn't pass, IIRC it was 2nd fast idle each time so gave up and got rid of it, i'm still gutted as it was a brilliant car, no rust in the rear wheel arch (or anywhere for that matter) and passed on everything else
This was my experience so unfortunately I'm not much help, hope you can get yours to pass [emoji106]
