Worn out struts on my Mercedes – any Dubai shops that specialize in air suspension?

I've got a 2015 Mercedes E350 with the air suspension and I've noticed over the last few months that the ride has been getting progressively harsher, and the car seems to sit a bit lower on the front left corner when it's been parked overnight. I know these air suspension systems are notoriously expensive to fix and I'm absolutely dreading the potential cost, but I also can't keep driving around with what feels like a collapsing spring because I'm sure it's going to cause uneven tire wear and eventually leave me stranded. I'm based in Dubai and I've been trying to find a specialist who actually understands how to diagnose air suspension issues properly rather than just swapping out components and hoping for the best. I've heard that some places will automatically tell you need new air struts when it might just be a leaky airline or a failing compressor, which would save a fortune. I came across some information and this suspension repair workshop serves Dubai, but I'd really prefer to hear from someone who's actually used them before I commit to spending what could be thousands of dirhams. Has anyone here had air suspension work done on their Mercedes in Dubai and can recommend a shop that's honest and reasonably priced? I'm also curious whether it's worth looking at refurbished air struts as a more affordable option, or if that's just asking for trouble down the road. I'm genuinely stressed about this because I love my car but I can't afford a 10,000 dirham repair bill right now. Any advice from people who've been through this would be really appreciated. Cheers.
