Legend, thanks.I believe the error/fault is just disabled.
The ecu knows there's an issue, but it's prevented from illuminating the light to show that.
The second sensor generally is still required to be plugged in, as without one, there's a different fault code which appears.
I was only wondering because when I get my decat I was wondering if I only need a straight pipe with a flared end or if it needs the lambda bung.
