Instructions for desiccant insert replacement

Special tools required:

  • 32 1 270

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 swarf (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.

The desiccant insert cannot be replaced in the following vehicles:

  • 1-Series E8x, 3-Series E9x from 12/2008
  • E84, E89
  • 1-Series F2x, 3-Series F3x
  • BMW i 01 without heat pump

In these vehicles, the condenser for the heating and air conditioning system must be replaced.

  • BMW i 01 with heat pump

On this vehicle the low pressure battery must be replaced.

Instructions for replacement of air conditioning capacitors and radiator/coolers

IMPORTANT: Even when they are correctly installed or due to normal driving, radiators (oil cooler, radiator, charge air cooler) or air conditioning condensers may show slight impressions or deformations on their discs (1).

A slight sag with a large radius for the air conditioning condenser is also permissible.

As long as tightness/function are not degraded and an adequate distance of a few mm between the radiator and air conditioning condenser remains in place, this is not damage in either case .

Radiators or air conditioning condensers are not to be replaced in these cases!

NOTE: The deformations shown can be bent back with a standard fin comb..

Damage to lines carrying media or on the flat pipe require exchange of the radiator or air conditioning condenser (2-6).

HVAC

Dryer flask (integrated in the air conditioning condenser): Round dents/depressions are permitted.

The air conditioning condenser is not to be replaced in this case.

Removing and installing or replacing capacitor for heating and air conditioning system

Special tools required:

  • 00 9 030

WARNING: Danger of injury! Refrigerant circuit is under high pressure! Avoid contact with refrigerant and refrigerant fluid.
