i am goin to take it back in a min to the garage to see wat they say but wud like sum advice ?? i will post a relpy to wat they say

Cheers in advance

Have you actually had the vehicle moving whilst trying the difflock ?

Its quite unlikely it will always come on / off with out the vehicle moving

yes i have tested it while moving for a short distance but it still doesnt come on ?

this is why it is confusing ?

200's do sometime take a while to come on, put it on and go for a drive on a straight road for a min dip your clutch see if it makes a differnece

wont goin straight on a normal road do damage ?? i have done about 50 meters down my street to see if it worked but it didnt!!!!

is ther a wire or a switch for this if so were???
