I may not be very helpful mate,but dont go for the cheapest, go for the best u can afford. oh and keep well on top of the maintainance, realy does pay off. Best of luck with the hunt!!
On a more constructive note......... when i had my freelander i had a similar prob, turned out to be a sensor that cost me 75 squid all in at main dealer.
Could anyone give me some tips/info on what upgrades n mods i can get for me Freelander? It's td4 03. I'd realy like to lift him n get some bigger tires on there if possible. Cheers guys!
