Hi - haven't fitted one but very interested in result as have one on the shelf waiting to be fitted to my aua engine (1.4 16v. Petrol). Like to know if engine light will come on as standard a2 petrol has two cats - one in the exhaust manifold and one post cat. Like to know if car will pass emissions test with only post cat and if any lights will come on in display showing fault code generated.
Cheers Dave
