Lambda now fitted so glad i had the pit to use
new ones cable was a lot shorter than the spliced in one manage to get it right up behind the heat shield and plugged in ok. Reset the code and reset my trip computer to.
On drive home lambda light came on again same code rear lambda so cleared it again and hasn't came back since so guessing ecu is taking a little time to adjust and realise new part is now fitted.
MPG went from low 19's up to mid to high 20's so happy with that going to save me some pennies in petrol now
