Vw ignition switches of those model years are known for this. It wont matter what you do to try slowing it down, the cylinder prematurely fails.

For a diy solution idea? My buddy’s finally failed with the key in on position. He was able to start it but not shut it off(couldnt pull the key out).He installed a killswitch in order to shut the car off and used his spare to lock it. He drove it that way for years before scrapping it.

VW should really cover this shit. Toyota ignition switches can probably last 100 years in comparison lol.

You said your new stud comes with the head already modded for installation, cut this old one. Dont even waste time grinding the head of it, just cut it , pull it out, install new stud

I don’t quite understand how you claim to not have time to do it, but then spend time writing this post about it and answer the comments on top of that lol. You coulda had all 8 plugs in your hands already.
