Audi A5 Window System Total Failure & Repair Guide

I had a similar issue with my 2013 A4 and have some experience with automotive repair and electrical issues. The symptoms you describe match exactly what happened to me, all power windows stopped working simultaneously. In my case, the main power window switch in the driver door was the culprit, not the window regulators or motors. The repair cost me 200 Euro including parts and labor. The workshop diagnosed it within an hour and the actual fix took about 2 hours. The window control module can fail due to moisture or general wear, affecting all windows at once since its the central control point. This is actually more common than multiple window motors failing simultaneously. Before proceeding with repairs, could you share: Do you hear any noise when pressing the switches? Does the problem persist with both the driver master switch and individual door switches? Have you noticed any other electrical issues? Is there any moisture damage visible around the switches? This information would help determine if your issue matches what I experienced with the faulty switch assembly.

Latest service at 123407 KM Thanks for the detailed response. Yes, I hear a clicking sound when pressing both the master and individual door switches. After checking more closely following your questions, I noticed the switches feel different than usual, less resistant when pressed. The door panel around the driver side control unit shows some signs of moisture damage, which makes your diagnosis seem spot on. No other electrical issues noticed yet. Would replacing just the main window control module fix this, or should I consider a full door panel replacement for proper automotive repair?

Based on your description, this definitely sounds similar to my A4 issue. The clicking sound combined with the different feel of the switches and visible moisture damage strongly points to a faulty window control module, just like in my case. The good news is you likely wont need a complete door panel replacement. The window control module can be replaced separately, which is much more cost-effective. When my car window issues occurred, the workshop only needed to replace the switch unit itself. For reference, the repair process involved: Removing the door panel, Disconnecting the old control module, Installing the new switch assembly, Reconnecting and testing all window functions, Recalibrating the auto up/down feature One thing I noticed post-repair was that the window regulator motor and window track mechanisms worked perfectly once the new control module was installed. Total repair time was around 2-3 hours. To prevent future issues, consider: Checking door seals regularly, Ensuring drainage holes are clear, Using water repellent on window seals The repair should cost between 200-300 Euro depending on parts availability. Make sure to get a proper diagnosis before proceeding with any repairs.

Thanks for all the input and comparison with your A4 experience. After getting your feedback and checking the symptoms more closely, I'm confident the window control module is the issue, especially given the moisture damage I found. I'll book it in for repair next week and have them focus on the switch assembly rather than the window motors or full door panel replacement. The 200-300 Euro estimate helps with planning too. The clicking sound and unusual feel of the power windows switches match exactly what you described. I'll definitely follow your maintenance advice about seals and drainage holes once it's fixed, don't want to face this issue again. I appreciate the detailed breakdown of the repair process too. It's reassuring to know the window track and other components should work fine once the control module is replaced. Good to hear the automotive repair was straightforward in your case. I'll update the thread once I get it fixed to confirm if it was indeed the same issue.
