Cheers greenjk yeah that was me! Working on some of the local creeks around the area
hit me up if your keen for a drive one day.
Thanks bluedriver, I actually had one of those obd2 WiFi scanners in but it wouldn't pick up any details of the error! I have had wheel speed sensors in the past so maybe it related? Need to invest in a better scanner too I think, just need to find one that works for the 4.7, most details seem to be on scanners for the diesel.
Needless to say I made it down the aptly named rocky track (double black dimond) without low range, even impressed myself what the WH is capable of with the right setup and no low range.
