Catalyst Fault with new Cat

[clyde]

Hi All

I've recently had my Cat replaced on my 1.6 petrol Mk1 Leon. However the engine management light comes back. I've taken it back to the garage where i got the Cat fitted and they have tested it twice and the emmissions test pass.

Anybody have any ideas?

Cheers!!

Have you checked if its the same fault?

I had the diagnostics run after the new cat was fitted and it was a Catalyst fault yes.
