As the title says, does anyone have a guide for doing this

I've been told you can do it without going under the car and also gaining access via the drivers side wheel arch with the steering on full lock

It's the sensor going to the manifold.

Any help would be much appreciated

 

Just jack up the car and remove drivers side front wheel, there is a flap in the plastic wheel tub when this is opened you can just use a lambda socket to undo it and then un plug it near the strut tower under the bonnet, should take less than half an hour to change.

 

Thanks Daz, just got back from holiday so will give it a go when I wake up !!!!
