Hi all... lots of bimmer sites.. just had the 84 325e detailed - amazing work, car looks new. will add pictures later. Problem: there are dead spots on the horn button. Horn is a circle at the center of the steering wheel. Disappointed that I couldn't find what I wanted in the Bently book and don't want to break anything. Can I just pry the center piece up to replace the horn ring???? It may just need to be cleaned!!
