Weird smell and spots in the parking, anyone know a good leak guy in Shabiya?

I'm a bit embarrassed to admit this but I've been ignoring a small leak on my 4 Series for about three weeks now because I kept telling myself it was just the aircon dripping. But the spots on the parking floor don't evaporate, and there's a faint smell that I can't quite place, somewhere between hot oil and something sweet. I'm in Shabiya and I need to get it properly looked at before I make things worse. Someone told me to look for expert leak detection and repair for BMW in Shabiya rather than just any garage that will top up fluids and wave me off, which makes sense because I'd rather know exactly where it's coming from. Can anyone here vouch for a place they've actually used in this area? I don't need the cheapest option, I need someone who will actually find the source instead of guessing. Also curious how long a proper leak diagnosis usually takes because I need the car for work next week.
