Have a look for my name on there i put breif instructions for setting the height

So swapping the sensors made no difference; the high voltage reading was still on the front left... I suspect that it is a glitch in the operating system that the autel (and other ‘cheaper’ diagnostic tools) uses... as there seems to be a commonality in the units that give these readings (where other more expensive readers do not). My next plan is to visit a friend (who runs a specialist garage - advanced diagnostics and electrical work) and plug into as many of his different diagnostic computers as possible and see what they show.
