Best advice I can give is get rid of the fecker or burn it
Nothing but a money pit I bought my Serengeti new in 2003 20k miles later head gasket goes then 12k later goes again IRD and VCU lasted 28k clutch 44k Gave the heap of ****e away in the end and got into proper land rovers , although there probably not much more reliable you don't get FAGS trying it on every time you get out of them
