Hi dropped into my local LR Independent garage today who I use all the time family run business fantastic service and help.I noticed a very very very small leak almost mist of oil on the casing external of the sway bar and asked if they wouldn’t mind looking.As ever they couldn’t be more then helpful I had previously cleaned it down with brake cleaner before going there around 25 miles from me.They looked it over and said not to worry I haven't had to top it up and they said Land-rover actually advise there will be a slight leak and not to worry as they have frequent Range Rovers in with same thing and they are still checking same car years later and same slight leak.To be honest from what they say it’s a common issue and as for Range Rover !!!! really you think it’s acceptable and almost set a acceptable tolerance anyway going to monitor it.Why is it as a Range Rover owner for every year you seem to age another 4 lol 😂
