Dashboard lit up like a Christmas tree on my Panamera

Dashboard lit up like a Christmas tree on my Panamera – electrical gremlins or something serious?

So I’m driving my 2017 Panamera 4S to work this morning, everything’s normal, and then suddenly the dashboard goes absolutely crazy – the ABS light comes on, then the PASM warning flashes, then the air suspension fault message pops up, and to top it all off the check engine light decides to join the party too. I pulled over, turned the car off, waited a few minutes, and started it back up, and all the warnings were gone like nothing ever happened. I drove the rest of the way without any issues, but now I’m sitting here at my desk completely paranoid that this is going to happen again at the worst possible moment, like on the highway or in the middle of nowhere. I’ve done some reading online and it seems like these kinds of multiple warning light episodes on Panameras can be caused by anything from a weak battery or failing alternator to a faulty ABS sensor or even a bad ground connection somewhere in the complex electrical system. The car is due for its major service anyway so I figure this is the perfect time to get everything thoroughly checked out, but I absolutely refuse to take it to the dealer because their diagnostic fees alone are just extortionate and they’ll probably try to sell me a whole new wiring harness or something ridiculous. I work near the industrial area so I’ve been asking around for a shop that really knows these cars and has the proper Porsche diagnostic tools, and a few people have mentioned looking for Premium Porsche repair and diagnostics in Musaffah because apparently that’s where all the serious independent specialists are located. I just want to find a place that can properly scan the car, pull the fault codes, and actually figure out what’s causing these random electrical gremlins without just guessing and throwing expensive parts at the problem until it goes away. Has anyone else experienced this kind of random warning light avalanche on their Panamera and found out what the root cause was? I’d really appreciate any advice or recommendations before I start throwing money at this thing.
