VW Golf 5 Wiper Problems: Fix & Repair

Hi.

This morning, while clearing the snow off my car, I noticed that I could move the windshield wiper arm on my Volkswagen Golf 5.
After I tentatively adjusted them to 45 degrees, I turned on the ignition and they remained in that position, but could be used normally and returned to their zero position without any issues.

After that, I was able to move it again.

After the car had been driven for a few kilometers (presumably with the wipers being used), the wipers are now firmly stuck in the zero position.

Is there a clutch in there that might be worn out?

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.
