Hi, Thanks for replying, the fault code was read by a diagnostic tool, said sensor 1 bank 1.
I was attempting to remove the sensor, but in the end, just gave up and replaced it! Only cost £56 for a new sensor, Thought the £130 quoted by the garage was a bit much!

Car's been properly fixed now!

On the down side, fog light glass has gone (stone hit it) So that's on order as well! I hate cars! >;o(
