I'm trying to find the post from a couple of months back ( I think). I've just spent ages searching - no luck ( but lots of other interesting stuff !! ) Can anybody help please. B5 1999.5 (facelift, July 1999 registration) I wish to check the coolant temperature via the climate module - there use to be lists of 'what and how' floating around years ago-- I suppose too many cars have gone to the scrap yard so it's no longer a hot topic! Thanks .
