Bmw Alpina B7L A/C Receiver Drier / Desiccant Element Kits

Bmw Alpina B7L A/c receiver drier / desiccant element kits

Starting at $32.95, AutoBuffy carries 1 A/C receiver drier and desiccant element kits for the Bmw Alpina B7L from brands including UAC. The receiver drier sits in the high-pressure side of the A/C system, filtering refrigerant and absorbing moisture. When it fails, moisture and contaminants circulate through the system, degrading cooling performance and damaging the compressor.

Signs your Bmw Alpina B7L needs a new A/C receiver drier or desiccant element

  • Warm or inconsistent air from the vents even when A/C is set to maximum cold
  • A/C compressor cycles on and off rapidly or fails to engage at all
  • Visible moisture, frost, or ice buildup on A/C lines near the receiver drier
  • Musty or foul odor from the vents caused by moisture-contaminated refrigerant
  • A/C system pressure readings outside normal range on both high and low sides
  • Recent compressor failure or refrigerant leak repair — drier must be replaced any time the system is opened

Which A/C receiver drier or desiccant element kit should you buy for your Bmw Alpina B7L?

The main decision is whether to replace the entire receiver drier assembly or just the internal desiccant element, which depends on your Bmw Alpina B7L's design and how long the drier has been in service. You should also confirm whether your system uses a receiver drier (common on TXV systems) versus an accumulator (common on orifice tube systems), as they are not interchangeable. OE-equivalent units are the safest choice for a reliable, leak-free repair.

Complete OE-Equivalent Receiver Drier Assembly
Best for
Most replacement jobs, especially when the system has been opened or the drier is more than a few years old
What you get
Full metal canister with fresh desiccant, new O-rings, and all ports matched to OE specs — drop-in replacement
Desiccant Element / Bag Kit Only
Best for
Systems where the outer canister is in good condition and the design allows internal desiccant access without replacing the housing
What you get
Replacement desiccant bag or cartridge sized to fit the existing drier housing, typically lower cost than a full assembly
Kit with Expansion Valve or Orifice Tube
Best for
Full A/C system refresh or when the expansion device is also suspect after contamination or compressor failure
What you get
Receiver drier plus matched expansion component — ensures the entire high-side filtration and metering circuit is renewed at once
OEM / Dealer-Sourced Assembly
Best for
Owners who require exact OE part numbers for warranty compliance or who want factory-matched materials and finish
What you get
Guaranteed fitment and OE material standards, typically at a higher price point than aftermarket equivalents

Replacing the A/C receiver drier or desiccant element on a Bmw Alpina B7L

Before removing any A/C component on the Bmw Alpina B7L, the system must be fully evacuated by a certified recovery machine — releasing refrigerant to atmosphere is illegal. With pressure relieved, disconnect the inlet and outlet lines from the receiver drier, noting O-ring positions, and unbolt the mounting bracket before unthreading or pulling the assembly free. After installing the new drier with fresh O-rings lightly coated in refrigerant oil, the system must be deep-vacuumed to remove all moisture and air before recharging to the specification on the Bmw Alpina B7L's underhood sticker.

Frequently asked questions

How much does it cost to replace a/c receiver drier / desiccant element kits on a Bmw Alpina B7L?
Parts alone start at $32.95 for the Bmw Alpina B7L. A full DIY job adds only basic tools and refrigerant recovery costs. Professional installation typically adds labor charges on top of parts, and shops will also charge for refrigerant recovery, evacuation, and recharge — budget accordingly when getting quotes.
How often should the A/C receiver drier be replaced on a Bmw Alpina B7L?
The receiver drier should be replaced every time the A/C system is opened for any repair, and many manufacturers recommend proactive replacement every several years regardless. Once exposed to atmosphere, the desiccant saturates quickly and loses its ability to protect the system from moisture damage.
Can I replace just the desiccant element instead of the whole receiver drier on my Bmw Alpina B7L?
Only if the Bmw Alpina B7L's drier housing is designed for internal desiccant access and the canister itself is in sound condition. On many vehicles the housing is sealed and must be replaced as a unit. Check whether a desiccant-only kit is listed for your specific application before purchasing.
Do I need to replace the receiver drier when replacing the A/C compressor on my Bmw Alpina B7L?
Yes. Whenever the A/C system is opened — including compressor replacement — the receiver drier must be replaced. Compressor failures often release metal debris and oil that saturate and destroy the desiccant. Installing a new compressor without a fresh drier risks contaminating and damaging the new compressor shortly after.
What happens if I don't replace a failed receiver drier on my Bmw Alpina B7L?
A saturated or clogged drier allows moisture and contaminants to circulate freely through the A/C system. Moisture reacts with refrigerant to form corrosive acids that erode the compressor, expansion valve, and evaporator. What starts as a minor drier replacement can escalate into a full system failure costing several times more.
Is a receiver drier the same as an accumulator on the Bmw Alpina B7L?
No. Both absorb moisture and filter refrigerant, but they are located differently and serve different system designs. A receiver drier sits on the high-pressure liquid line and is used with thermostatic expansion valve (TXV) systems. An accumulator sits on the low-pressure suction line and is used with orifice tube systems. Confirm which your Bmw Alpina B7L uses before ordering.
