Looking for capable Jaguar AC service in Sharjah – any solid leads?

Honestly, I'm at my wit's end with my Jaguar XF's air conditioning. It's been a nightmare for the past few weeks – one day it's ice cold, the next it's warm, and now it's warm constantly. I've already had it re-gassed twice at a local garage, but the problem came back within days both times, so I've learned my lesson about taking it to people who don't really know these cars. I've read that Jaguar AC systems are pretty complex with electronic temperature regulators and multi-zone control units, and common issues include refrigerant leaks from the condenser or evaporator, failing compressors, and faulty pressure sensors . I'm based in Sharjah and I've seen a few places that claim to work on Jaguars – there's Al Tayer Motors on Sheikh Mohammed Bin Zayed Road for official dealer service , and I also found a garage called AMA AUTO SHJ in Industrial Area 11 with a 4.8 rating that lists Jaguar among the brands they work on and covers AC repairs . But I'm looking for a shop that offers Capable Jaguar AC Service Available with proper leak detection and full system diagnosis, not just a quick gas top-up that fails again. Has anyone here actually used a workshop in Sharjah that properly diagnosed and fixed their Jaguar AC without endless follow-up visits? I'd really appreciate a solid recommendation before this summer heat gets even worse because driving around in this without AC is just miserable.
