Hello Friends,
If any of you has access and can share 2011 GL350 refrigerant line routing, I would really appreciate help. Having A/C leak issues. 150psi test drop to 100psi overnight - so far not finding leaks with soap. I believe I put dye in the system 2 years ago, but also can't find visible spots. It's been over a year since I had refrigerant in the system, so it might be just washed out.
If no help, I might just add dye and charge with refrigerant again and try to locate it after few day. Unless it's evaporator (would explain why I'm not seeing anything), which would also suck.

Unfortunately, once the system looses its pressure, that can allow moisture to enter the AC system and destroys pretty much everything with rust. (compressor, drier, evaporator, etc.)
