View Full Version : A/C Compressor Oil

For the A4 1.8T (and maybe everything else), does the A/C compressor need more PAG oil after 16 years? Is there a way to check level or is the oil just in a vapor state in the lines?

If it isn't broken, don't fix it. System is suppossd to be sealed, and the oil you had in there should still be there.
