Air Conditioning Refrigerant Fill Capacity and Information
MODELS:
All
Information:
The following is a listing of reference information for servicing BMW Air Conditioning systems. Please refer to these chart when evacuating/recharging BMW A/C systems.
Note:
That some 1993 Model Year early production R-134a equipped vehicle 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 shown before refilling. Labels with the lower refrigerant charge amount will be phased into production along with the charge amount. BMW will inform dealers when the labels are available for spare parts usage.
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 new labels, as soon as they are available. However, inadvertent refrigerant charging up to the fill capacity given on the original under-hood label will not cause any problems.
Warranty Status: Information only.
