Hi Paul,
So you have now discovered the wipers and washers do not work with the bonnet open! Good isn’t it?
Someone at VAG’s good idea, probably because due to one particular model’s wipers possibly catching on the edge of an open bonnet - or something!
Re. a tutorial of using a meter. If this was my car, I would not be connecting a meter to anything on the car, if you are asking how to use a meter. These, like most other ‘modern’ cars, are ‘electronically sensitive’ and it is not advisable to go around connecting test lamps and the like unless you are competent.
Appreciating the car is off the road, but I would now stick with my original suggestion and buy an hour’s services of a (mobile) auto electrician - it could be a lot cheaper in the long run.
Kind regards,
Gareth.
p.s. Wiper stalk at fault? Could be.
