VW Scirocco Wiper System Complete Failure Fix Guide

I had a similar issue with my 2012 VW Golf, pretty much identical wiper system to your Scirocco. As someone with moderate experience working on VWs, I can share what worked for me. Initially thought it was the wiper motor, but after having it checked, turned out the wiring harness had a loose connection near the steering column. The rain sensor was working fine, but the signal wasnt getting through due to damaged wiring. Took it to a workshop where they diagnosed and fixed the cable connection issue. Total cost was 95€ for the repair including labor. Been working perfectly since then. Before you start replacing parts, would be helpful to know: Does the wiper system make any noise when activated? Are you getting any specific error codes? Did the problem start suddenly or gradually? Do the wiper blades move at all, even slightly? These details would help narrow down whether its actually the switch, wiring harness, or wiper motor causing the issue. The symptoms on these VW models can be quite similar regardless of the root cause.

Last service was at 71000km and honestly it started suddenly with no warning. No noise at all when hitting the switch, completely dead. Getting error code P0520 on the dash. Wipers are completely frozen, not even a slight movement or sound when trying to activate them. The turn signal and cruise control work fine, so I am thinking the steering column itself isnt the problem. Been checking forums and most point to either a faulty wiper motor or switch, but wanted to get more opinions before spending money on parts. Thanks for mentioning the wiring harness, hadnt considered that. Will definitely have someone check the connections before replacing anything.

Thanks for those additional details about your Scirocco. When my Golf had the issue, it also showed zero movement or sound, just like yours. However, my experience suggests its probably not the wiring harness in your case, the symptoms are different from what I encountered. Given that your turn signals and cruise control are working normally, and the complete lack of response from the windshield wipers, Im now leaning more toward the wiper switch being the culprit. When my wiring harness failed, there was at least some intermittent function before total failure. The error code P0520 on VW models is often tied to electrical issues in the wiper circuit. In my repair journey, I learned these switches commonly fail due to worn internal contacts. A new wiper switch costs around 85€ and its a relatively straightforward fix. Before you replace anything though, a quick test you can try: Toggle the wiper switch between all settings multiple times. Sometimes the contacts just need a bit of movement to temporarily restore function. If you get even a slight response, that would confirm the switch theory.

Great info from both of you. The error code P0520 combined with the complete lack of response definitely points to the wiper switch. I can confirm after getting my hands dirty that its a common failure point in these VW models. Got the part for 82€ and decided to tackle it myself since the wiper motor and other systems seemed fine. The swap was pretty simple, just had to remove a few trim pieces around the steering column to access the switch assembly. Took about an hour total. Car wipers are working perfectly now, and the error code is gone. Really glad I didnt jump straight to replacing the more expensive components. Though I might get the wiring harness inspected during the next service just to be on the safe side. Thanks for helping me diagnose this correctly. Would have probably wasted money replacing the wrong parts without your input on the symptoms and testing process.
