Macan Key Fob Acting Up? Antenna Could Be The Culprit

Hey there, I had a similar issue with my 2015 Porsche Cayenne Diesel last winter. Initially, I also thought it was just the key fob battery, but it turned out to be the antenna cable connection in the front bumper. When I took it to my trusted independent Porsche specialist, they diagnosed a partially damaged cable that was causing intermittent connectivity issues with the key fob. The cable had some wear and tear where it connects to the antenna module. It wasn't a major repair, but it needed to be fixed properly to avoid complete failure of the keyless system. The fix involved replacing the antenna cable and checking all connection points. The whole job took about 2 hours. Since then, my key fob has been working flawlessly, no more unusual failures or inconsistencies. Not a serious issue in terms of car safety, but definitely something that needs proper attention from someone who knows what they're doing. Make sure whoever does the work uses genuine Porsche parts for the replacement. Hope this helps.

Hey, thanks for sharing that, sounds exactly like what I'm dealing with! I'm actually leaning towards getting this fixed at an independent specialist too. Just curious, do you remember roughly how much you ended up paying for the repair? And has everything been running smooth since, or did you run into any other quirks with the system?

Hey again! Yes, I can give you a precise update, I had it fixed at my independent specialist and it cost me 260€ in total, including parts and labor. The repair involved replacing the damaged cable connection to the bumper antenna, and I'm happy to report it's been working perfectly ever since! To be honest, it was definitely worth every penny. It's been over a year now since I had it done, and I haven't experienced a single problem with the key fob system. No more of those frustrating unusual failures or having to walk around the car trying to find the "sweet spot" to get it to work! Seriously, if you're experiencing similar symptoms, I'd recommend getting it checked out sooner rather than later. The peace of mind of having a properly working key system is worth it, and it's actually not as expensive as you might think when you go to an independent specialist rather than the dealer. Let me know if you need any other info, happy to help a fellow Porsche owner!

Thanks so much for all that info! I actually went ahead and got it fixed yesterday at an independent specialist you inspired me to try. My experience was pretty similar to yours, turned out it was indeed the antenna cable that was acting up. The whole thing cost me around 280€, which wasn't too bad considering how annoying the problem was. The mechanic was really thorough and even showed me the worn-out cable. Got it all sorted in about two and a half hours, and I've been testing it like crazy since then, works perfectly now! No more dancing around my car trying to get the key to work! Really glad I asked here and got your advice instead of heading back to the dealer. The independent specialist was way more personable and actually took the time to explain everything. Definitely keeping their number for future repairs. Thanks again for pointing me in the right direction, you saved me both time and money!
