Driving around this morning just before I arrived home I heard a strange metallic crack noise but afterwards didn't feel any difference in the way the car drove and thought nothing of it. Started the car up a couple hours later and had a engine light on the dash and "check emission" message.
Scanned and got P0420 code - catalytic converter system bank 1 - efficiency below threshold
Monitored both pre and post lambda sensor voltage and once warm they both pretty much followed each other.
I guess it's looking likely that the cat has failed/cracked? Can anyone confirm before I try to get hold of one.
My pre-cat (on the manifold) is already gutted I believe so I'd be looking for a secondary one if anyone has a oem exhaust in the North East/North Yorkshire area?
