Power Windows Dead? RS7 Window Fix Guide

Had the exact same problem on my 2014 RS6. With some car repair experience, I can tell you it turned out to be a faulty power window switch in the driver door panel. Initially thought it was the window regulator motor, but the fact that all windows were affected pointed to the main control unit. The workshop diagnosed it through proper testing of the window control module. They confirmed the switch pack was sending incorrect signals, causing all windows to fail. Total repair cost was 200 Euro including diagnosis and replacement of the driver side main switch panel. Key signs that helped identify the issue: All windows stopped at once, No manual control working from any door, Error codes present in system, No mechanical noise when pressing switches Before going for a complete regulator replacement, having the window switch unit tested could save money. The car window mechanisms themselves were perfectly fine in my case. Could you share: If you hear any sounds when pressing the switches, Whether the windows worked from other door controls, If this happened suddenly or gradually, Current mileage on your RS7 This would help determine if your issue matches what I experienced with my RS6.

Thanks for the detailed feedback on the window control issue. My RS7 has 193982 KM and had its last service 3 months ago. When pressing the switches, there is zero response, no clicking, humming, or mechanical sounds. This happened suddenly after a heavy rain, and none of the window controls work from any door panel. I notice the one-touch function light on the driver door is also completely dark. Just checked again following your points, the window mechanism seems dead from all positions, suggesting it could indeed be the main switch rather than individual window regulators. This might save me from unnecessarily replacing multiple components. The symptoms match your case exactly. Will have the main switch unit tested first before considering more expensive automotive repair options. This sounds like a much more cost-effective approach than my initial plan.

Thanks for providing those additional details about the symptoms. The rain event you mentioned strongly supports the switch diagnosis, as water infiltration through the door panel seal can directly affect the window control module. This matches exactly what I discovered with my RS6. After my repair, I actually learned that water damage to the main window switch is a known weak point on these models. The connection between the door panel wiring and the window control unit can become corroded or short circuit after water exposure. The lack of any response or indicator lights is a classic sign of a failed switch unit rather than a mechanical window regulator issue. My advice based on the matching symptoms: Have the switch unit tested first, Check the door panel wiring harness for moisture damage, Ensure the door weather seals are intact to prevent future issues The repair should cost around 200-250 Euro if it is just the switch unit. A full window regulator replacement would be closer to 600 Euro, so starting with the switch makes sense given the identical symptoms to my case. Just make sure whoever does the work properly dries and protects the new window control module during installation. This prevents the same moisture-related failure from recurring.

The symptoms you described match my situation perfectly, and I appreciate your detailed analysis of the power window system. The rain correlation and complete electrical silence definitely point toward the switch unit being the culprit, just like in your case. Will schedule a diagnostic appointment focusing on the window control module and door panel wiring first. The cost difference between replacing just the switch unit (200-250 Euro) versus multiple window regulators makes this approach much more logical. Your insight about water damage being a known issue with these models is particularly helpful. When getting it repaired, I will make sure they check all door seals and properly protect the new window control unit from moisture. This has saved me from potentially spending hundreds more on unnecessary window regulator replacements. Will update once I get the switch unit tested and hopefully confirm this as the fix. Really helpful to learn from someone who went through the exact same power window failure and found a cost-effective solution.
