I've got a 2004 S430, VIN: WDB NG 70J64A412537

My AC compressor died, so I am replacing it along with the expansion valve, dryer, condenser, and flushed everything else. So now I need to replace the oil.

I've found two references in the WIS for oil amounts that should go into each component and they agree EXCEPT for oil added to a new AC compressor. One reference suggests 120 ccm and the other 20 ccm. If it wasn't such a vast difference in quantity, I would just wing it.

For anyone with AC experience, how much PAG oil should I put into a NEW AC compressor that essentially has no oil in it from the factory?

Thanks,
Russ

So by the lack of response, I assume this is not an easy question to get answered.

I'm attaching images of the two referenced documents that I’ve been looking at. The specific information is circled in RED. In the longer document, you have to scroll to page 6.

At this point, all I need to do is add PAG oil and connect the AC hoses. While I'm vacuuming the system down, I can install the wiper system, radiator and power steering pump so I can finally drive my car again!

120 grams. I don't know how this relates to cubic centimeters listed on the sheet you posted. See attached.

Thank you! I seem to recall grams converts directly to cc in the meteric system. I've been REALLY bogged down with this AC system and hope to get it put back together soon, hopefully today. 'Too bad I'm sick and feel like crap....
