My S-Class air suspension is acting weird again
-
I've got a 2016 S-Class that I bought second-hand about two years ago, and honestly it's been one of the most comfortable cars I've ever owned, that magic body control suspension is just incredible when it's working properly. But over the past month or so I've noticed that the car seems to be sitting lower on the rear passenger side when I come out to it in the morning, and it takes a good few minutes of driving before it levels out again. I know these air suspension systems are notorious for developing leaks as they age, and I'm pretty sure that's what's happening here, but I'm also aware that it could be a faulty valve block or even just a sensor issue that's throwing things off. The dealership quoted me a price for diagnosis that was frankly ridiculous, and they wanted to keep the car for three days just to look at it, which I can't really manage with my work schedule. I've been asking around in some of the local Mercedes groups and a few people have mentioned that going to a good independent specialist is actually the smarter move for these older cars, because they often have more experience with common issues and can diagnose things faster without all the dealership bureaucracy. I'm hoping to find trusted Mercedes service in Abu Dhabi that can properly diagnose this without trying to upsell me on a whole new suspension system when it might just be a simple seal or hose issue. Has anyone else dealt with this kind of overnight sagging on their S-Class and can tell me what the fix ended up being? I'd really appreciate any insight before I start spending money on this.
