Question Second set of eyes on AC project

Hello All,

I have a 05 ML500 which has recently began to have AC issues. About every 2 weeks the AC runs hot due to loss of freon. I did the quick fix with the UV dye to find the leak. After checking all the normal parts, the only place I see the leak is on the expansion valve. I have done other fixes to AC system in other cars, but wanted just to get a second set of eyes from anyone out there to tell me if the pictures attached look to be saying "expansion valve leak". Its almost summer here in Arizona, so wanted to make sure my project was correct before starting!

Thank you!
