2011 Touareg V6

Almost exactly the same story as mine then. The relay is clicking often.My problems started a few weeks ago after the last fishing trip of the season. Car sat on a parkinglot over the weekend and the temperature went from 0ish to -20 or so. I started the car and got a running gear fault. I couldnt hear the compressor and the car hadnt sunk from any corner, so I figured frozen silica in the moisture trap was the issue. I drove back home and had the car sit for 3 days in a warm garage, but the problem persisted.
So I started calling shops and, no suprises here, they all wanted to start replacing parts. One shop offered to test the compressor first, so I took there. They replaced tested it with direct current and said it was broken. They quoted me a new one for 1400€ + work. So I asked if they would install parts that I provided and they said yes. So I ordered a new one from Germany for 430e + delivery and took it to the shop. They installed it and I got the car back. This had fixed the running gear error and car seemed to work fine.
The next day I went about my day, driving from jobsite to jobsite around the countryside for a total of 350ish km. I noticed the relay for the compressor was clicking often. I couldnt hear it running over the roadnoise but whenever I stopped I could hear the compressor running for 15 to 20 seconds, stopping and starting again every few minutes. So I got home and called the shop.
I took the car back with the understanding that the shop would check the system for leaks. The car was not dropping from any corner, but I figured it might leak from somewhere close to the compressor. They took almost a full day to check the car and found no leaks, but discovered that the air accumulator only had 3-4 bars of pressure in it. They tried to get the compressor to build pressure, but it wouldnt, despite running. At this point I had googled the issue alot and knew about the nitrous fill. I asked them to do it, but they didnt have the right tool to fit the accumulator.
So now I have the car back, wondering what to do next.
Mine is back in the shop, and they said it’s not building the correct pressure, and they suspect the new compressor is faulty. They’re trying with a new one on Monday.
I asked them again about the nitrogen filling, and they said it’s correct but that they’ve stopped doing it. The same has Møller (the absolute main VAG chain in Norway) - stopped doing it. They say it’s not that big of a difference, and that the nitrogen will be switched out with air after a while anyway. But if I manage to find a place that will fill it, I’ll do it.
