Audi S tronic jerking in slow traffic – any recommended gearbox shop in Sharjah?

I’m at my wit’s end with my 2018 Audi S5’s dual-clutch transmission. In stop-and-go traffic, it jerks and hesitates when crawling in first gear, almost like it’s learning to drive all over again. Highway driving is perfectly fine, which makes me think it’s not the clutches themselves but maybe the mechatronic unit or just a software issue. The dealership quoted me a fortune just for a diagnostic and potential adaptation, so I’d rather find an independent specialist. I’ve been searching around and heard that the Best Audi Gearbox Repair Sharjah can be found in Industrial Area 6, but I don’t want to just pick a random shop from Google. Has anyone here actually had their S tronic fixed in Sharjah for a reasonable price? I’m hoping it’s something simple like a fluid change and reset, but I need a place that has the proper VCDS or ODIS tools and won’t try to upsell me a whole new gearbox. Any real recommendations would save me a lot of stress and money.
