RS5 Sunroof Dead: Reset vs. Repair Guide

Had the same sunroof operation problem on my 2012 Audi S5. The sunroof control module completely failed, causing the entire system to become unresponsive. A sunroof reset procedure was attempted first, holding the switch in various positions, but proved ineffective. The root cause turned out to be a failed control module requiring replacement and sunroof calibration. This is a known issue affecting several vehicles in this model range. While independent shops can handle the hardware replacement, the automobile sunroof system needed proper coding and calibration using specialized diagnostic equipment. The repair involved: Removing headliner, Replacing sunroof control module, Performing full sunroof reset, Coding the new module, Testing all sunroof positions This was definitely a serious repair requiring specific diagnostic tools and expertise. The shop needed to perform a complete sunroof calibration after installing the new module to ensure proper function of all positions and the anti-pinch safety feature. Given the mileage on your RS5, this sounds very similar to what I experienced. Would recommend having it properly diagnosed rather than attempting DIY fixes, as incorrect calibration can cause further issues.

Thanks for sharing your experience with the sunroof mechanism issue. Mine also got fixed last month and the sunroof operation is working perfectly now. The symptoms you described match exactly what happened with my car, completely unresponsive sunroof controls and a stuck sunblind. Can you remember roughly how much you paid for the entire repair? My bill was quite steep at 1200 Euro but curious to compare. Also, has everything been working properly since the fix, or have you noticed any other quirks with the sunroof system?

The sunroof troubleshooting on my S5 actually worked out cheaper than yours, around 950 Euro total for parts and labor. The sunroof control module replacement was the bulk of the cost. Since having the mechanic address the issue last week, including the 75 Euro coding work, the Sunroof not initialized error has been completely resolved. The sunroof mechanism has been working flawlessly for the past 3 years with no recurring problems. The sunroof control operates smoothly in all positions, and the anti-pinch safety feature works exactly as intended. The sunblind movement is also perfect, no sticking or hesitation. One tip: I regularly clean and lubricate the tracks as recommended in the manual to prevent future issues with the automobile sunroof system. This basic maintenance seems to help keep everything running smoothly.

Glad I could get this resolved. After seeing your response about the Sunroof control module, I took my RS5 to a specialized shop last month. The diagnosis confirmed exactly what you mentioned, a failed module requiring replacement and recalibration. The total repair came to 1200 Euro, which included: New sunroof control unit, Complete sunroof calibration, Labor for headliner removal, System coding The automobile sunroof has been working perfectly since the fix. The sunroof mechanism moves smoothly, and the sunblind operates without any issues. Really appreciate the tip about track maintenance, have already added regular cleaning to my maintenance routine to avoid future problems. Started noticing the issue when the sunroof controls became completely unresponsive one morning. Initially tried the basic sunroof reset procedure myself, but quickly realized this needed professional attention. The shop completed everything in one day, and the sunroof operation is now back to factory specifications.
