On older cars, only material was used, no foam. Perforated leather, canvas, etc. Even on older VWs this didn't happen, VW Beetle, Golf Mk1, Mk2. Since the generation of the Golf Mk3, material with foam has been used and after a certain time the foam burns and the canvas starts to separate and hang. That's the problem.
Yes, the procedure is the same. The only difference may be if you have a model with metal hooks instead of screws, but this is not a problem. Good luck with the works.
