RS5 Keyless Entry Failure: Antenna Fix Needed

Having faced similar issues on my 2015 S5, the automotive antenna system was indeed the culprit. The signal interference affected both the keyless entry and the start function, requiring manual key insertion. The car antenna repair involved replacing the antenna module and checking all related wiring connections in the front bumper area. The issue stemmed from corroded connections where water had seeped in around the antenna housing. This affects both radio signal reception and key fob communication. Initially considered DIY but discovered the repair requires specialized diagnostic equipment to properly calibrate the new antenna system with the vehicle. The job involves removing front bumper components and careful routing of antenna cables. Without proper tools, there is risk of damaging other electronic systems. This was a serious repair requiring dealer-level diagnostic capabilities, though not mechanically complex. The symptoms match exactly, keyless entry failure followed by push-start issues, while the car runs normally otherwise. Worth noting that temporary fixes like cleaning connections or repositioning existing components rarely solve the underlying antenna system deterioration at this mileage point.

Thanks for sharing your S5 experience. My RS5 has been in the shop for a week now getting the antenna mount and wiring harness replaced. The symptoms were identical, first the keyless entry became unreliable, then the push start stopped working completely. Did you remember roughly what the total repair cost came to for your antenna system replacement? Also curious if youve had any related electrical gremlins pop up since getting it fixed? My mechanic mentioned possible interference with other systems that share the same wiring loom, so wondering if I should watch out for anything specific.

After taking my S5 to the mechanic, the vehicle antenna issue was completely resolved. The total repair came to 95 Euro, which covered fixing a faulty cable connection at the antenna mount. Much more reasonable than I initially feared. The repair has held up perfectly with no signal interference or electrical problems since. The keyless entry and push start functions work flawlessly now. Your mechanic is right to mention potential complications with shared wiring, but in my case, fixing the antenna connection actually improved the overall electrical system stability. The FM radio reception is also much clearer now, which was an unexpected bonus from the antenna replacement work. Been about 8 months since the repair with zero issues, no gremlins or related problems have surfaced. The key is getting a proper diagnosis and repair of the root cause rather than just addressing symptoms. Worth mentioning that water intrusion was the main culprit in my case, so making sure the new antenna installation is properly sealed is crucial for preventing future issues.

I finally got my RS5 back from the shop today after the antenna repair saga. Total bill came to 850 Euro for the complete antenna replacement and wiring harness work. More than expected but worth it to have the keyless system working properly again. The car radio and push start functions are both working perfectly now. Turns out the original antenna mount had completely deteriorated, letting water seep in and corrode the connections. The signal interference was worse than initially thought, affecting multiple systems. Mechanic showed me the old parts, pretty shocking how bad the corrosion was after 188k miles. They had to replace more wiring than initially planned due to water damage spreading through the harness. Glad I went with a proper repair shop rather than attempting this myself, since accessing everything behind the bumper was way more complex than expected. No electrical issues since the fix and the keyless entry is more responsive than its been in years. If anyone else runs into similar symptoms, definitely worth getting it checked before the problem spreads to other systems.
