You’re miss reading something… you don’t have to pull the engine.
Check your local library too see if they have a copy of the Bentley Service manual of your year VW. There is also the Muir book “How to keep your Volkswagen alive: a guide for the complete idiot” I’m not sure but I think this is covered in there. The local public library should have a selection of service manuals, look for Chilton?s and the Bentley.. they are the best.
All else fails, try and find a local VW club and ask for help…..
