Purely an optional repair this but I'd like to get it done at some point....

I've been rummaging round today having a look for any obvious reasons why the A/C is leaking on the D5. ATS did a pressure test on the system with O2 free Nitrogen and the machine detected a 'leak' (the reason for system not working then ). So, they were unable to charge it back up for obvious reasons (legal and common sense) and I wouldn't want them to if there was a leak even if they could. They did the UV wand test and couldn't see any dye leaking anywhere although I think it was a superficial look and they didn't charge me for the 'service'.

So before I cart it off to an A/C 'specialist' for the proper dye treatment, I thought I'd have a look in case the solution was smacking me in the face. I visually checked as much of the pipework as possible, I noticed what appears to be an A/C related pipe going along the bottom of the radiator, I/C, Condenser assembly to the Condenser itself and this looked rather rusty on the surface but nothing obviously rusted through.

I also noted the condenser has seen better days and on a side note, there is a bolt missing from the lower n/s that holds the 3 units together so I wonder if the assembly has been completely apart at some point in the past, and something damaged during reinstallation. Another thing I noted is that the condenser seems to be 'bowed' which may indicate that it's damaged and will need replacing, PFV sell them for around £165 although I imagine it's a bumper off job, radiator drain and complete disassembly to change the units over (in other words a PITA).

A photo of the bottom of the condenser, perhaps this is normal but it doesn't look right to me. By comparison, the unit on the T5 looks nearly new by the way!
