Air Conditioning Refrigerant Fill Capacity and Information

All
Information:
The following is a listing of reference information for servicing BMW Air Conditioning systems. Please refer to this chart when evacuating/recharging BMW A/C systems.
Note that some 1993 Model Year early production R-134a equipped vehicles have under-hood labels that specify higher charge values than those specified here and in the microfiche. Testing has confirmed that the values given here are the optimum fill capacities. Consult the chart before refilling. Labels with the lower refrigerant charge amount specified on the chart have been phased into production as of 11/92.
When performing repairs to the A/C system that require recharging, only the specifications given in this S.I. should be used, as well as the label part numbers, as appropriate (see chart). However, inadvertent refrigerant charging up to the fill capacity given on an "original" ('93 MY production prior to 11/92) under-hood label will not cause any problems.
