Hi Scotty. I have recently bought a golf mark 4 from 2000 in great condition but i was wondering about some of the cables. It seems that the insulation on most cables i have had contact with has become sticky. Is this just an old car thing or is it a sign of something wrong in the electrical system?

if you mean the wiring insulation is coming off, that's because of VW cheap wiring materials. It is not a good thing, at least tape up the really bad ones. Rewiring the whole car is not worth it

Well, of curse it is not a good thing! The car is 17 years old so I cant really complain, plus it is otherwise in really good condition and the insulation is more just sticky to the touch than falling off at the moment.
Main concern was if there was some kind of electrical issue that would cause this or if is it natural ageing?
