My Brera 3.2 failed its MOT yesterday, any advice?
I think you may just have a faulty lambda probe. I’d change it, and have a universal flex welded in - on, I assume the front pipe, then resit the car for its MOT.
A faulty exhaust, or 02 sensor will mess with the emissions..
These cars chuck out lots of C02 as it is with a good exhaust
Plus, I’d hazard a guess a faulty cat would show an EML light..
Even a 02 sensor would.
Does the engine light flicker on and off?
