Hi Guys
As the title says my Lex went for its MOT today and failed on emissions.
It was high last year but some fuel treatment sorted it out but this year it 's being more stubborn.
The garage I use are trying to give it a run tomorrow, and hoping to bring the readings down, but i'm not too optimistic.
I'm thinking maybe Cats or a Lambda sensor but the garage admit they can't diagnose it and don't want to randomly change sensors/ ecu's.
Is it best to take it Lexus (Nottingham) if the treatment doesn't work, and will they be able to make an accurate diagnosis?
Sorry about all the questions, feeling a bit panicky .
Hi to everyone by the way, i've not been in for a while.
Regards
Adz :winky:
