Mercedes 6.9: Options when buying a new AC compressor?
« on: 14 March 2021, 12:40 PM »
Looking to purchase a brand new high quality AC compressor for my 6.9.
Believe the original unit is of the A6 type.
Typically made back in the day by GM (General Motors).

So what options do I have for a brand new compressor?
Preferably not made in China (is that even possible these days?)

Is it correct and verified that the original unit does NOT have a superheat switch?
Should the compressor wiring connectors be at the so called 10 o’clock position or at the 2 o’clock position?

I believe it’s also recommended to replace the receiver drier when doing the compressor.
Anyone having the correct Mercedes part no. for this?

Any help and input appreciated. Thanks

Gents,
I’ve now been informed that the Mercedes 6.9 compressor part number is:
000 230 49 11.

Ac Parts then informed that this A6 compressor is the correct unit for the 6.9:

Any thoughts on this? Thanks
