Dragging up an old thread, but it is a good one! 2 years ago I had a pressure sensor fault, so got it replaced and the garage reported that it initially seemed to leak and then held its pressure so they were able to recharge it and I picked it up working. Only lasted a few days, and when I checked again the pressure was low, so I tried topping it up and using superseal, but ran out of gas before it was working properly and then didn't have time to touch it again for ages and it went to the bottom of my list, and covid meant I wasn't really using the car last summer. Obviously with the hot weather I wanted to get it working again so got a can of gas and to my surprise needed very little before the pressure came up good (both on the dial on the filling adapter, and in VCDS). But no cold air. I was flicking through the measuring values for ages trying to spot what was wrong. Thanks to this thread I am now pretty sure it is going to be the N280 valve, since pressure is OK, compressor is running etc. and the only thing wrong is that the current is around 80.5-82, which it seems corresponds to a stuck valve. Then the light bulb moment, I put bloody superseal in it 2 years ago, I wonder why the valve could be stuck? No warning about that on the can, says only suitable for belt driven not electric driven compressors, but fails to mention belt driven compressors controlled by a solenoid valve rather than a clutch... I mean, it could be something else, but seems highly unlikely after reading the 8 pages of this thread. Now to see if my normal garage (not the one who looked at it 2 years ago) can change the valve for me, or compressor if necessary. I bet they are flat out.
