Hi there - looking for a wiring diagram for the windscreen washer pump. No power getting to the pump. Is there a fuse somewhere? Does not seem to be one in the fuse box. Also get intermittent flashing of the brake warning light on the onboard computer - wondering if there is a common trunk. Any help will be appreciated. Oh, also had a VAG diagnosed error "Temp Sender Unit... ground to earth" or something like that. Any ideas?

There are three.

Had a problem with the temp sender unit if I recall correctly of the radiator..... any sign of a wiring diagram. Bentleys do have a CD-ROM - but expensive for non US citizens.
