VW Taos Radio System Dies, Static Noise and Zero FM

I experienced nearly identical issues with my 2020 VW Tiguan. The radio interference and complete signal loss pointed to a faulty antenna system. After diagnosis, it turned out the antenna amplifier had failed completely, causing the error messages and static noise. The repair involved replacing the antenna booster module and checking all antenna ground connections. Static noise often indicates either a damaged signal amplifier or loose ground connections. In my case, water had entered the antenna housing, corroding the electronics inside. This is typically not a serious mechanical issue, but it requires proper diagnostic equipment to verify the exact fault. The vehicle electronics need thorough testing because similar symptoms can come from multiple sources, damaged wiring, corroded connections, or failed components. The fix restored full functionality to both FM radio and the entire infotainment system. The stored error codes cleared after repair and haven't returned in 18 months of regular use. Key advice: Have them specifically check the antenna ground connections and signal amplifier module first. These components commonly fail on VW models from this generation.

Thanks for the detailed explanation of the antenna amplifier issue. My Taos had the same problems last year and your experience matches exactly what happened. The car radio static and FM signal problems drove me crazy until they found the faulty ground connection and damaged amplifier module. Would you mind sharing what the total repair cost was in your case? Mine came to 480€ with parts and labor, but prices might have changed. Also curious if youve had any vehicle electronics issues since the repair?

After getting the antenna and ground connection fixed at the shop last week, the radio reception is perfect now. The total repair cost was 255€, which seems reasonable compared to your bill. Honestly, it was worth every cent since the poor signal and constant static noise were really frustrating. The mechanic found water damage in the antenna housing, just like in your case. They replaced the amplifier module and properly sealed everything. The FM signal strength is now excellent and all those error messages have disappeared completely. Havent experienced any radio interference or vehicle electronics problems since the repair. The infotainment system works flawlessly and maintains strong signal reception even in areas where I used to lose connection completely. Looking back, the antenna ground issue was definitely the root cause. Having a proper diagnosis saved time and prevented unnecessary part replacements.

Thanks everyone for sharing their experiences. Just got back from the shop and wanted to close this thread with my results. The mechanic confirmed it was indeed the antenna system causing all those problems. After running diagnostics, they found corroded wiring near the antenna mount and a completely dead signal amplifier. The static noise disappeared as soon as they replaced these parts. What a relief not having that awful sound anymore! The final bill came to 480€ including parts and labor. Might seem steep, but the poor signal quality and constant error messages were driving me crazy. They also applied extra weatherproofing around the antenna to prevent future water damage. Now the radio picks up stations perfectly and the infotainment system runs without any glitches. No more signal strength issues or system errors. Really glad I asked here first, helped me understand the problem before heading to the shop. Best part is the repair was done in just a few hours. The investment was worth it considering how much I use the audio system during my daily drives.
