COMPATIBILITY

The BMW parts catalogue identifies 61126943538 specifically as a driver’s-side seat wiring set for the BMW E92, for vehicles equipped with:

S459A – Seat Adjustment, Electric, With Memory. (Hubauer-Shop)

BMW 3 Series E92 Coupé

Suitable for selected E92 variants including, depending on production date and seat specification:

• BMW 318i E92

• BMW 320i E92

• BMW 320d E92

• BMW 325i E92

• BMW 325d E92

• BMW 330i E92

• BMW 330d E92

• BMW 335i E92

• BMW 335d E92

• Other E92 derivatives equipped with the corresponding electric memory driver’s seat

IMPORTANT: Compatibility is primarily determined by the seat specification and wiring configuration, rather than engine size.

BMW used different seat wiring harnesses depending on vehicle production date and equipment.

E90 / E91 / E93 COMPATIBILITY

Do not automatically assume compatibility with E90 Saloon, E91 Touring or E93 Convertible.

BMW’s parts catalogue lists different wiring-set numbers for several of these applications. For example, 61126943539 is shown for certain E87/E90/E91 driver’s-seat applications, while 61126943538 is specifically associated with E92. (Hubauer-Shop)

Therefore, this listing should primarily be advertised for the BMW E92 Coupé unless the buyer has confirmed compatibility by matching the wiring harness and connectors.

TECHNICAL INFORMATION

The driver’s seat wiring harness distributes electrical power and control signals between the components fitted within the electric seat assembly.

Depending on vehicle and seat equipment, connections can include:

• Electric seat adjustment motors

• Driver’s seat memory module

• Seat adjustment control switches

• Seat heating components

• Seat position / adjustment components

• Vehicle power supply

• Seat-related electrical connectors

• Associated comfort-system connections

The harness is routed through the seat structure using factory mounting and retaining points.

ELECTRIC MEMORY SEAT SYSTEM INFORMATION

BMW’s electric seat with memory system allows the driver’s seat position to be electrically adjusted and stored for later recall.

The wiring loom is an important part of this system because it provides the connections required between the various electrical seat components.

A damaged harness can interrupt power or communication to individual seat functions even when the adjustment motor or seat module itself is functioning correctly.

COMMON SYMPTOMS / REASONS FOR REPLACEMENT

A replacement seat wiring harness may be required due to:

• Electric seat adjustment not operating

• One or more seat adjustment functions intermittent

• Memory seat function not operating correctly

• Damaged or broken wiring beneath the seat

• Broken electrical connectors

• Wiring damaged during seat removal

• Harness trapped or cut by the seat mechanism

• Corroded electrical connections

• Replacement following interior or seat refurbishment

• Replacement electric seat requiring the correct factory loom

IMPORTANT DIAGNOSTIC INFORMATION

Before replacing the wiring loom, check:

• Seat fuses and power supply

• Seat adjustment switches

• Seat control / memory module

• Electric adjustment motors

• Electrical connectors beneath the seat

• Wiring for visible cuts, crushing or corrosion

• Vehicle-side electrical connection

A non-working electric seat does not automatically mean that the wiring harness itself has failed.

INSTALLATION

The wiring loom installs within the driver’s front seat assembly using the original BMW connector locations and wiring routes.

Depending on the repair, removal of the seat from the vehicle may be required to correctly access and route the harness.

IMPORTANT: The seat area can contain SRS / airbag and seat-belt restraint electrical connections.

The battery should be disconnected and the correct BMW repair procedure followed before disconnecting restraint-system connectors.

Professional installation is recommended.

PROGRAMMING / CODING

Replacement Wiring Loom Only: Normally no coding required.

If the original seat modules and vehicle configuration remain unchanged, replacing a like-for-like wiring harness normally does not itself require programming.

However, retrofitting electric memory seats into a vehicle that was not originally equipped with them is different and may require additional wiring, control modules, power supply modifications and vehicle coding.

IMPORTANT COMPATIBILITY NOTE

Please compare:

61126943538

Also compare:

• Connector quantity

• Connector shape and colour

• Wiring layout

• Seat adjustment specification

• Memory-seat equipment

• Vehicle production date

• Listing photographs

BMW E92 seats were available with different electrical configurations, so matching the vehicle model alone is not sufficient.

For best compatibility, the buyer should match the OE/reference number and electrical connectors with the original harness.

CONDITION

Used Genuine BMW Part.

Normal cosmetic marks and signs of previous installation may be present.

Please inspect all listing photographs carefully for the exact wiring loom, connectors, condition and components included in the sale.
