So this seems to have become intermittent (i.e. a pain in the bum). When I had VCDS on last week it gave a no voltage or jammed error (I can't recall what it was and it's on the other computer...). Then it suddenly freed itself off without me doing anything other than clearing the error code.....but is resolutely non-operational again just to annoy me.

How much of a job is it to fix this - or is there some quick fix I can take to limp it through until we are in warmer weather (and have got all the other niggles from SWMBO's accident sorted out....).

Cheers,
Dan.
