It's likely to be the post cat sensor (was on mine) and fairly common after fitting a bigger downpipe & hi-flow cat.

You may be able to use a spacer piece (as shown in the link above, in post #29).

Post cat sensor is the one after the cat on the Leon Cupra R... I see you have an Ibiza, don't know if they're the same with 2 sensors, one before the cat, and one after :confused:
