It was only installed about 6 months ago, and has spent 3 months of that off the road!
I think the wiring is okay, it is all new - lambda sensor is located in downpipe approx 4 inches from flange
4 inches from the turbo flange can be a bit hot for certain wide band sensors. Try mounting the new one a bit further down stream but before and not too near any joints. Also make sure any exhaust sealant you use does not contain silicone.
