Sounds like the EVAP temporarily froze. The next question is if it's not a leak how does VW keep that from happening and why it failed. Clogged drain? Temp sensor? TXV failure?
I'm taking it to an independent shop in the morning. They have a R1234yf machine.
I've been reading reports of failing EVAP coils on BMW models of this vintage. They're R1234yf as well.
No errors according to my Ancel VD700
I find it odd that it would suddenly begin cooling again.
If you read the entire thread, your question would be answered.
I mean a stored fault code. I clicked on the reddit post and I didn’t see it.
DId.you turn off the AC or keep it running? If you kept it running then perhaps it's a compressor issue where it's not cycling on as it should. If you turned it off and then back on perhaps the ice on the EVAP coil melted. I had an icing problem with my 435i. It happened twice where on low fan speed and at 70 degrees it would ice up on the highway but if I raised the temp to 72 or higher it wouldn't ice. My solution was to turn off the AC and crack the sunroof which would allow the ice to melt fairly quickly.
I'm not sure. My wife was over there mashing buttons. We kept the fan speed on high. After it started cooling, I put it in manual mode. I instructed her to never use the automatic mode again.
