Please help keep this thread on topic. If your reply isn't about significant refrigerant leakage on MK5/6 ('09+) TDI, don't post here.
So there's no shortage of A/C threads regarding the RCV for MK5/6; but I've seen at least a dozen of these '09+ cars with little to no 134 in the system. Like <100g when there should be 500-550g. Systems seem to be unadulterated. Typically these are cars with <100K miles on them, and while the system is nearly identical to the earlier MK5s, I have not seen any early MK5s low on refrigerant without obvious cause.
I've charged a couple of them only to have it all leak out again in short order. Now I'll be the first to admit that I'm probably not the world's greatest A/C refrigerant leak locator, but damned if I can't find anywhere suspect. I've used dye and UV, and I've bought a somewhat fancy electronic leak detector too. They're not leaking fast enough to detect with vacuum alone, or soapy water under normal operating pressures.
The forum hit results are all drowned out with owners having (a) RCV issues (b) smoked compressors (c) "dealer fixed it for free under warranty" (d) baseless, useless, fectless whining about their sweet new car.
The only TSBs I found were for (a) RCV (b) compressor "clutch" blows up (c) check pressure valve seal. Well, the pressure sender on a CR is on a long spindly aluminium tube, and when I get a 17mm on the sender all I'm doing is twisting the tube, so I didn't do that. Might as well just replace the whole line if it's gonna break when I try to replace the o-ring on the sender per TSB.
I figure before I invest in a dry nitrogen tank so I can pressure test the systems at 300psi or so and look some more, I figured I might put a feeler out to techs and owners that have experienced significant refrigerant leakage on MK5/6 TDI with common rail engine.
