Ended up being "the A/C line"... waiting on the truck and paperwork to come back this afternoon via Service Valet. Estimated at around $2k with a replacement key fob, so I'm happy I made the $1590 ESP purchase from Granger.That was exactly my reaction.
Dealer confirmed the system had zero pressure (completely empty) and threw P0534. They did a vacuum test, sniffer, etc. and couldn’t find a leak, then recharged it and everything works now.
Their explanation was basically:
“If there is a leak, it’s too small or conditional to detect right now.”
Which I get in theory, but like you said—refrigerant doesn’t just disappear. So either there is a slow/intermittent leak that hasn’t revealed itself yet, or it lost charge under some condition they can’t replicate in the shop
They also said if it leaks down again, that’s when it usually becomes diagnosable (UV dye shows up, etc.) and then it would be a covered repair.
Curious what you end up finding out. Please let me know!
