997 Battery Woes: Help Finding Reliable Porsche Repair

I experienced something very similar with my 2013 Porsche Cayman S last summer. The symptoms were identical, weak battery signs, dim lights, and warning lights. Turned out it wasn't actually the battery, but a faulty cable connection to the control unit that was disrupting the BUS system communication. Took it to my trusted mechanic who specializes in Porsche, and they diagnosed it quickly. The repair involved replacing some corroded cables and reconnecting the control unit properly. It wasn't a hugely complex fix, but finding the actual problem required proper diagnostic equipment and expertise with Porsche electrical systems. I'd strongly recommend finding a Porsche specialist rather than a general mechanic for this. These electrical issues can be tricky to diagnose without the right equipment, and misdiagnosis could lead to unnecessary repairs. The issue isn't severe if caught early, but it can cause bigger problems if left unaddressed. BTW, 142k km isn't bad for a 997, these cars are built to last when maintained properly.

Hey, thanks for sharing your experience! That sounds exactly like what I'm dealing with. Glad to hear it wasn't anything too major in your case. Mind if I ask how much the repair set you back? Also, curious if you've had any other electrical gremlins pop up since getting it fixed? Really appreciate the advice about going to a specialist, definitely makes sense with these cars.

Hey there! Happy to give you an update. After getting it fixed at my specialist, I haven't had a single electrical issue, the Message error completely disappeared. The total bill came to 260€, which included diagnosing and fixing the faulty cable connection to the control unit. Honestly, considering it solved the problem completely, I think it was money well spent. My Cayman's been running like a dream since then, no electrical gremlins or any other weird issues. I think catching it early before it could cause any cascade of problems really helped. My mechanic explained that these connection issues can sometimes pop up in Porsches as they age, but once properly fixed, they typically stay fixed. If your symptoms are similar to what I experienced, you're probably looking at a similar repair. Just make sure you go to someone who really knows their way around Porsche electrical systems. These cars have pretty specific quirks that general mechanics might miss. Let me know how it goes when you get it checked out! Always happy to share experiences with fellow Porsche owners.

Just wanted to update everyone! Finally got my 997 sorted out. Took it to a Porsche specialist like suggested, really glad I did! Turned out it was pretty similar to what experienced. The mechanic found some corroded connections in the electrical system. Total bill came to around 300€, which included a thorough diagnostic check and fixing the faulty connections. A bit more than I initially hoped for, but way better than replacing the entire battery or dealing with bigger issues down the line. The car's running perfectly now, no more dim lights or warning messages. Started up this morning like it was brand new! Really appreciate everyone's input, especially about going to a specialist. Saved me from potentially making the wrong choice with a general mechanic. Lesson learned: when it comes to Porsche electrical issues, it's worth paying a bit more for someone who knows what they're doing. Thanks again for all the help!
