Dear forum, today I wanted to grease the wiping stick of my GP0 because of squish noises, so that the mechanics did not even “festfrisst”. I want to lubricate with “brunox”. (oil for peeping). is that also suitable? have removed the covering over the water box. then I wanted to remove the wipers myself, so that I can get the wind deflector behind it and better see the mechanics. the wipers are fixed with each one nut (behind a cap). these have been solved. but then was not able to pull them up.WIESO? did I forget something? does someone have an idea? VIELEN DANK and gruß marc
