Instructions for desiccant insert replacement
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2019 MINI Cooper, 2018 MINI Cooper, 2017 MINI Cooper, 2016 MINI Cooper, and 2015 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.
Special tools required:
A desiccant insert that is in a correctly functioning, sealed heating and air conditioning system does not have to be changed at regular service-inspection intervals.
However, the dryer flask or desiccant insert must absolutely be replaced in the event of:
- contamination of the refrigerant with shavings (e.g. when the compressor is clamped).
- With depressurized and/or completely drained refrigerant circuit.
- With a refrigerant circuit, which was closed using special tool 32 1 270 but remains open for more than 24 hours.
