Hello, Ive just signed up to this group so hello to all. I have a sportbrake 3.0dS and have been towing with it for just under a year, we have just changed our caravan to something a little heavier and it seems to be a little unstable. The towbar is a witter and fitted by a tower specialist. I have read on the net that the car may need to go back into Jag to have the software updated (a cost of £104 as HAFox) does anyone know what this software update does? as I cannot work out if its is just to disable the reversing sensors and high level brake light, or does it activate the Trailer Sway Mitigation system? Any help would be great, PS great cars and love mine.
