Try greasing the number plate. That way nothing can stay on the plate.
if you go to Kwik Fit, that is what you get as they are not mechanics and are only interested in quick easy turnarounds.
I might add that they have daily targets to meet so therefore the advice you get from them isn't always to your advantage.
You will have to bite the bullet and take the time to book an appointment with the electricians if you want it fixed.
Hope this helps.
