S-Class suspension noise – any honest Mercedes specialists in Dubai?

I've been driving my 2016 S-Class for about two years now and it's always been a dream, but recently I've started to notice this low-level rattle from the front suspension whenever I drive over cobblestones or rough patches of road, and it's really taking the edge off the magic carpet feel that made me fall in love with the car in the first place. I've taken it to a general garage for a quick look and they said it might be the stabilizer bar links or possibly the lower control arm bushings, but they weren't confident enough to give me a definite answer without taking things apart and charging me for a full diagnostic. I'm not opposed to spending money on proper work, but I want to make sure I'm taking it to somewhere that actually knows these air suspension systems inside out rather than a place that'll just guess and replace parts until the noise goes away. I found suspensionrepairdubai.ae/ which seems to cover a lot of the common suspension issues on luxury cars, but I'd feel a lot better if someone here could give me a solid recommendation based on real experience. I'm in Dubai and I really want a workshop that's transparent, uses genuine parts, and won't try to convince me I need a full suspension overhaul when it might just be a simple fix. Has anyone had a similar rattle on their S-Class and found a specialist who sorted it out properly? Also, what kind of cost am I looking at for something like replacing stabilizer links and bushings on one of these cars? Any advice would be massively appreciated because I'm keen to get this sorted before it gets worse. Cheers.
