Since I need the car, a new timing belt pulley was installed, and everything that secures it was fixed!
Have you tried searching for information about the timing belt pulley problem in this forum? If you do, you'll notice that if the crankshaft stub wasn't properly machined/leveled, the new pulley probably won't last long, no matter how it's bolted on.
I just wanted to quickly let you know that my car is currently at VW, and the damage is being repaired :Dfree of charge}. The whole process has been going smoothly without any major discussions. I'm not yet aware of the specifics of what's being done, but I'll let you know as soon as I have more information.
