I've been putting this off for way too long and now it's finally come back to bite me. My 2019 Cayenne S has been giving me these little hints for the past few months that the battery was on its way out, but I kept telling myself it was fine and I'd deal with it later. It started with the start-stop system becoming really unpredictable, sometimes it would work perfectly and other times it would just refuse to engage, and I'd get a message on the dash saying start-stop unavailable. I didn't think much of it because honestly I find that system annoying anyway, so I wasn't too bothered. Then about three weeks ago, I noticed that when I unlocked the car, the puddle lights and the mirrors would unfold a bit slower than usual, which was a bit weird but again I convinced myself I was imagining things. But then last week, I went to start the car after it had been parked for about two days, and the engine cranked over so slowly I genuinely thought it wasn't going to start. It did eventually fire up, but it was that horrible laborious crank that makes your heart sink for a moment. I took it for a long drive thinking I'd charge it up, but the next morning the same thing happened again. So now I'm in a position where I absolutely need to get the battery replaced, but I'm really particular about who touches my car because these Porsches are so sensitive to voltage and battery type. I've heard horror stories about people fitting the wrong spec battery and then having all sorts of electrical issues, from transmission faults to suspension errors, all because the car didn't have the right voltage parameters. I've also been told that you absolutely must have the battery coded to the vehicle using the proper diagnostic equipment, otherwise the car will overcharge the new battery thinking it's still the old one, which ruins it within a matter of months. I called the dealership and they quoted me a price that was honestly shocking, I mean I knew it wouldn't be cheap but I didn't expect it to be that high. I'm hoping there's a good independent specialist in Abu Dhabi who knows these cars inside out and can do the job properly without charging dealership prices. I've seen a few places around town that claim to work on premium German cars, but I'm always a bit skeptical because having the right equipment and actually knowing how to use it are two completely different things. What I'm really after is a shop that understands the importance of using the correct lithium or AGM battery depending on the car's configuration, because I know some Cayennes have different battery types and you can't just swap them around. I came across a service that offers Porsche car battery fitting in Abu Dhabi by premium technicians, and it sounded like exactly what I need, but I'd really like to hear from someone who's actually used them or a similar place before I commit. I'm also curious about whether they do a proper health check of the charging system and look for any parasitic drains that might have contributed to the battery failing prematurely, because I'd hate to fit a brand new battery and then have the same problem again in a few months if there's an underlying issue. If you've had your Porsche battery replaced at a good independent shop in Abu Dhabi, could you please share your experience, let me know the rough cost, and whether they did a thorough job with the coding and diagnostics. I'm planning to get this sorted out this week because I've got a few trips coming up and I really don't want to be stuck somewhere with a dead battery and a car that won't start. It's such a fantastic car to drive when everything is working properly, and I just want to get back to enjoying it without this niggling worry in the back of my mind every time I turn the key.
