2003 3.0 - Calsonic Kansei - Refrigerant Oil

[e53 lover]

I'm a proud owner of an E53 3.0 that has a failed Calsonic Kansei compressor (CSV717).

I've been hunting for the amount of refrigerant oil that our AC systems use but couldn't find anything until today.

So... assuming the evaporator, condenser and compressor are replaced does this label mean that I only need to add 120 cm^3 of oil for our AC system?

I can't see a total oil amount listed but this document talks to the amount of oil to be added during a service...

I cant remember how much oil it called for. I added some via a Freon can I had that had compressor oil in it but the compressor claimed to be pre-oiled so I just winged it via the can I had having oil in it.

Has worked flawlessly. 38 degrees normally at 90 outside.

Sorry Im not more help than that.

Thanks - this led me to the information I needed. After rummaging through the TIS (64 52...), I ran across this important language:

The new air conditioning compressor is filled at the factory with refrigerant oil.
The amount of refrigerant oil in the new air conditioning compressor corresponds to the amount of refrigerant oil for the entire new and unfilled refrigerant circuit.

Best way to determine how much oil to put back in with the new compressor is to drain the oil from the old compressor and put back in the same amount.

What you say is true IF I were ONLY replacing the compressor. I'm replacing the evaporator, condenser, and compressor and also flushing the lines.

"upallnight" is correct, do NOT trust what the repair manual says.
My experience with Denso is: the new AC Comnpressor can carry any amount of oil, not necessarily the correct amount.

I replaced my E39 1998 528i AC Compressor (it is a Denso).
The E53 X5 is probably very similar.

awesome diy - very detailed.

i think we're misinterpreting a couple things. i agree that "upallnight" is correct when you ONLY replace the old compressor with a new compressor of unknown oil amount - in-fact the TIS states exactly what "upallnight" recommended. so to say do NOT trust what the TIS states is a bit extreme.

what i learned from your diy is - measure how much pag oil is really in the compressor before installing
