Hi all I hope that someone can help me out here!

I have a 1.8 99 freelander, now with some added extras that i dont want any more,

My rear wiper when turned on wont stop wiping the rear screen, I have tried a new rear motor but still it keeps going.

Also my rear window wont open from the alarm fob like it should.

I tried to start the CCU test but it wont start, ie key on hold for light etc..

And now the bloody car does like running when cold at low revs, revs can drop right down???

So i would like to know if anyone can help me out... and with ideas for software to read the faults?

Many thanks..........
