The front flex pipe had a hole in it so that section was replaced which included the cat. The lambda sensor was also replaced at the same time. Just took for a retest and its failed again with the MOT tester saying that the readings were pretty much the same.
Anyone know whats next? I'm assuming plugs and maybe fuel filter but beyond that i can't think why the engines running rich.
It may be connected but occasionally its rough when starting from hot, takes a few cranks for the engine to start.
Help...

My V6 2.5 failed on emissions the chap at the garage popped in two bottles of forte cleaner told me to go for 15 mile drive give it some wellie and return, did this and it passed emissions test

Hi all,
Thanks for all the advice. Following a new flex pipe and cat, a bottle of fuel injector cleaner and ahem a spirited drive down the motorway and a couple of hours labour fitting a new exhaust sleeve, I'm now a proud owner of a legal car again. Next step, fix the worn shock tower bushings and patch a hole that has appeared in my front bumper...
