Component Purpose and Function
The BMW Air Conditioning Compressor Mounting Bracket is responsible for the rigid, repeatable, and load-resistant mounting of the compressor to the M57N2 diesel engine. Appropriately designed bolt points and contact surfaces reduce vibrations, minimize stress in the compressor housing, and support correct accessory belt routing.
This component belongs to the Air Conditioning Compressors and Clutches category, playing a crucial structural role in the entire system. Without stable mounting, it is difficult to maintain the correct drive geometry and the reliability of the air conditioning operation under demanding operating conditions.
Benefits of Using an Original BMW Bracket
Using the factory-specified mounting in the M57N2 engine in E90, E91, and E92 body styles allows for the preservation of manufacturer-intended parameters. The most significant advantages include:
- Factory Fitment – maintaining the correct compressor position relative to other engine accessories.
- Stable Load Transfer – reducing the risk of cracks, play, and unwanted vibrations in the air conditioning system.
- Compatibility with Original BMW Design – no need for modifications, custom spacers, or bracket adjustments.
- Maintaining Proper Accessory Belt Operation – correct belt routing affects the durability of pulleys, the tensioner, and the compressor itself.
Product Characteristics and Condition
The offered bracket is an original BMW component, meaning it retains material and dimensional compliance with factory specifications. The item is a used part, making it a cost-effective solution for repairs or reconstruction of the air conditioning system in vehicles with the M57N2 engine.
Choosing a used, original mounting is particularly attractive where a combination of OEM quality and a reasonable service budget is important – especially for comprehensive work on engine accessories, compressor replacement, or engine rebuilds.
Practical Service Applications
The air conditioning compressor mounting bracket in BMW E90, E91, and E92 models with the M57N2 engine is often replaced during:
- Installation of a different air conditioning compressor – after a failure or when replacing with a functional unit,
- Collision repairs – when the front of the vehicle and engine accessories have been damaged,
- Engine swaps and transplants – to maintain full compatibility with the factory air conditioning system.
Using an original mounting component simplifies the mechanic's work, reduces fitting time, and minimizes the risk of issues with belt tension, noise, or accelerated compressor wear.
