As suggested, a tiny leak can throw it right off and mess the cat due to the misfuelling, sorting the leak and a dose of Catclean will help.Nick9one1 wrote: ↑Sat May 19, 2018 9:38 am Fail again..
He didn't give me another fail certificate as I'd have to go though the whole test again. Instead I've got 1 week left to have another retest.
It was reading 1.045 - higher than last time!
He did say there was a slight leak just before the backbox which could be causing it.
I should have asked him to test both sides, but I forgot!

With the leak being after the cats/o2 I didn't think it would matter, but I'll fix it and try again.
On the second dose of catclean now.

Just had the emissions checked at a different garage and it passed with flying colours now the leak is fixed.
Booked in for the retest at 2pm.

It's amazing how a tiny leak can really screw things, your MPG should improve no end as well

You're right! With the hole being so far back I didn't expect it to skew the reading so much.
It was massively under the maximum limit of 0.2 with a score of 0.06.
So you definitely can pass emissions with primary cats removed!
