Macan's Key & Lock Mystery: Having Troubles

Hey there, I had a similar issue with my 2015 Porsche Cayenne last year. The symptoms were almost identical, warning lights, central locking acting up, and starting problems. Initially thought it was just the key fob battery, but turned out to be the key slot reader in the car itself. The Hall sensor in the slot was defective and needed replacement. Got it fixed at the official Porsche service center. The repair involved replacing the complete key reader unit since these components aren't sold separately. It wasn't a complex job, took them about 2 hours to complete the work, but the parts had to be ordered specifically for the car. This is actually a known issue in some Porsche models from that era. It's not a major mechanical problem, but it needs to be addressed since it affects basic car functionality and security. Would definitely recommend going to an authorized Porsche dealer for this specific issue, they have the right diagnostic tools and genuine parts for these electronic components. Hope this helps narrow down your problem.

Thanks for sharing your experience! Yeah, that sounds exactly like what I'm dealing with. Good to know it was just the key reader unit, I was worried it might be something more serious. Do you remember roughly how much you ended up paying for the fix? And has everything been working smoothly since then? I'm thinking of heading to the Porsche dealer in my area, but you know how those bills can get pretty scary!

Hey again! Just wanted to update you on my experience, since getting it fixed at the Porsche dealer, my Cayenne has been running perfectly! The total bill came to 290€ for replacing the key reader unit in the ignition slot, and honestly, it was worth every penny. The Hall sensor malfunction is completely gone now, no more warning lights, no more central locking issues, and the car starts like a charm every single time. I totally get your concern about dealer prices. But for these electronic components, I really think it's worth going to the experts. They diagnosed it quickly and had the right parts on hand. Plus, they give you a proper warranty on the work, which gives some peace of mind. Just make sure to book an appointment in advance, they can get pretty busy. But yeah, your symptoms sound identical to what I dealt with, so hopefully it'll be a straightforward fix for you too! Let me know how it goes if you decide to get it done.

Wow, thanks so much for all the details! I actually just got back from the Porsche dealer yesterday. You were spot on, it was the key reader unit! The whole experience was way better than I expected. Made an appointment last week, dropped off the car in the morning, and they diagnosed it right away. The mechanic showed me the faulty unit and explained everything clearly. Bill came to 310€, which wasn't as scary as I'd imagined. They even gave me a loaner car while they fixed mine. Best part? The car's working perfectly now! No more warning lights, locks working like they should, and starts up every time. Really glad I took your advice about going to the dealer instead of trying to save a few bucks at my old mechanic. Thanks again for sharing your experience, it really helped me make the right decision! Sometimes it's worth paying a bit more to get things done right the first time.
