No mate, jack it up and crawl underneath. You will see the VSS it is situated at the rear of the gearbox and should be covered by what looks like a tin foil bag. Pull the bag up a bit and unclip the plug off it, then its just one bolt to change the sensor. Refit the plug and pull the bag back down again to cover it, job done.
