take the unit out, its a 200 tdi which means your system could be up to 20 yrs old... circuits corrode after a while, get rid of it

am in catterick, for a few weeks if you need a hand, its been a while since ive had a landy in bits, my welding is not that good so dont ask, but would be willing to give u a hand if u need it,

wd40 stops a belt squeak, it also draws moisture out from the rubber makin it brittle, (over time) stops the squeak till u get round to doin it, may possibly be w/pump, can be replaced in a few hours... dont forget the bent spanner ( viscous coupling)
