BMW 3 Series E90 Replacement Rearview Mirror Housing Shell Pair

This replacement rearview mirror housing provides a targeted solution for BMW 3 Series E90 owners facing issues with the exterior shell of their vehicle's side mirrors. Whether due to physical damage, sun fading, or general wear, the outer housing can detract from the car's appearance while the internal mirror mechanism remains fully functional. This product addresses that specific problem by offering the outer casing alone, allowing for a cost-effective refresh without the expense of a complete mirror assembly. It is engineered to match the original contours and attachment points, ensuring a factory-style finish once installed. Available for two distinct production periods and in two visual finishes, it caters to the precise requirements of different E90 model years.

Features and Construction

This mirror housing is defined by its specific vehicle compatibility and material construction. It is not a universal fit item but is precisely shaped for the BMW 3 Series E90, which is critical for a seamless appearance and proper mounting. The product separates the model years into two groups: those produced from 2006 to 2008, and those from 2009 to 2012, as the mirror design underwent changes. This attention to detail ensures buyers receive the correct geometry for their car. The housing is sold as a pair, covering both the driver's and passenger's side mirrors symmetrically.

Material and Build

The housing is moulded from ABS plastic. ABS is a common material in automotive exteriors due to its favourable balance of properties: it offers good structural rigidity to hold its shape, has a degree of impact resistance to minor knocks, and demonstrates stability under various weather conditions. The manufacturing process for this component likely involves injection moulding to achieve the complex curves required to match the BMW's design language. The finish applied—either a standard black or a simulated carbon fibre pattern—is designed to integrate with the vehicle's existing trim and colour scheme.

Size and Practical Fit

The product's compatibility is its primary measurable specification. It is made to correspond with several original BMW part numbers, including 51167135098 and 51167205291 for the different model years. This correlation indicates it is intended to be a direct substitute for the genuine part. The installation method is described as 'replacement installation', meaning the old housing is removed and this new unit is fitted in its place, utilising the existing mounting points and mirror mechanism. The packed dimensions of 27 cm by 20 cm by 15 cm indicate a compact product suitable for standard shipping and storage.

Uses and Placement

The core use for this product is the restoration or repair of the side mirror assemblies on a BMW 3 Series E90. It serves a functional and cosmetic role, protecting the internal components of the mirror while defining a key part of the car's side profile. Its application is squarely within the realm of automotive maintenance and DIY repair for the vehicle owner, or for use by professional workshops carrying out similar refurbishment work.

Event or Professional Use

For professional automotive repair shops or detailers, this product represents a efficient parts solution. It allows a technician to address a customer's complaint about damaged mirror housings without needing to source and install entire new mirror units, which are more expensive and may require electrical disconnection. It can be a valuable stock item for specialists working on BMW models, enabling them to offer a tailored repair service that maintains the vehicle's originality. The clear division by model year and finish helps professionals select the correct part quickly.

Everyday Home Use

For the car owner, this housing enables a manageable DIY repair project. Replacing a cracked or discoloured mirror shell can significantly improve the car's aesthetic without the complexity of dealing with the mirror's glass, motor, or heating elements. The project typically requires basic tools and aligns with the skill level of an enthusiast. Choosing between the black or carbon pattern finish also allows for a minor personalisation, letting the owner select a look that matches other trim elements or personal preference, while still retaining an OEM-style appearance.

Benefits and Buying Value

The value of this product lies in its specificity and practicality. It solves a discrete problem—a damaged mirror housing—without forcing the buyer into a more extensive and costly repair. By focusing on the shell alone, it offers a middle-ground solution between living with damage and undertaking a major replacement. The benefits are measured in terms of restored appearance, maintained vehicle integrity, and cost efficiency relative to a full assembly.

Reuse and Low Maintenance

This product leverages the principle of component-level repair. In many cases, the core mirror mechanism—the glass, motor, and wiring—within the old housing is still fully operational. This housing allows that expensive internal assembly to be retained and reused, merely updating its external protection and appearance. Once installed, the ABS plastic shell requires minimal ongoing maintenance beyond occasional cleaning, as it is designed to withstand typical automotive environmental exposure.

Why Choose This Product

A buyer would choose this specific mirror housing because it is explicitly designed for their BMW 3 Series E90, down to the model year and original part number correlation. This reduces the risk of purchasing an ill-fitting aftermarket part. The availability of two finishes provides a choice between a standard replacement and one with a more distinctive carbon pattern. The decision is driven by a need for an exact match to repair damage, a desire to refresh aged trim, or an intention to perform a straightforward upgrade without altering the vehicle's fundamental character.
