Genuine BMW 3 Series E92 Coupé Front Right Electric Seat Control Adjustment Motor – 405019 / P10155901

Genuine BMW/OEM used front right electric seat adjustment motor, removed from a BMW 3 Series E92 Coupé.

This motor forms part of the electrically adjustable front seat mechanism and provides powered movement for one of the seat adjustment functions.

Part Number / Marking: 405019

Additional Number: P10155901

Part Type: Electric Seat Adjustment / Control Motor

Position: Front Right Seat

Vehicle Side: Right / O/S

Application: Electrically Adjustable Front Seat

Vehicle: BMW 3 Series E92 Coupé

Condition: Used Genuine/OEM Part

COMPATIBILITY

Suitable for selected:

BMW 3 Series E92 Coupé

• E92 3 Series models equipped with electrically adjustable front seats

• Front right seat application

• Petrol and diesel models depending on seat specification

• Pre-LCI and/or LCI compatibility depends on the exact seat mechanism and motor configuration

Potential applications can include selected:

• BMW 318i E92

• BMW 320i E92

• BMW 320d E92

• BMW 325i / 325d E92

• BMW 330i / 330d E92

• BMW 335i / 335d E92

• Other E92 derivatives with the matching electric seat mechanism

Engine size is generally not the determining factor for this component. Compatibility depends primarily on the seat type, electric adjustment equipment, motor function, production date and connector configuration.

E90 / E91 / E93 COMPATIBILITY

BMW used related electric seat mechanisms across the E9x generation, including:

• BMW 3 Series E90 Saloon

• BMW 3 Series E91 Touring

• BMW 3 Series E92 Coupé

• BMW 3 Series E93 Convertible

However, do not assume direct interchangeability between all E90/E91/E92/E93 seats.

Seat frames, adjustment mechanisms and individual motors can vary according to:

• Body style

• Standard / Sport seat

• Electric seat specification

• Memory-seat equipment

• Production date

• Driver / passenger position

• Individual adjustment function

For this reason, the listing should primarily be advertised for the BMW E92 Coupé, with other E9x applications requiring physical and number comparison.

RIGHT-HAND DRIVE / POSITION INFORMATION

This motor is identified as a front right seat component.

On a UK right-hand-drive BMW E92, the front right seat is the:

Driver’s Seat / O/S Front

For left-hand-drive vehicles, the same physical right-hand position would normally correspond to the passenger side.

Buyers should therefore compare the physical seat position and motor configuration, rather than relying only on “driver” or “passenger” terminology.

TECHNICAL INFORMATION

BMW electrically adjustable seats use several electric motors and mechanical drive mechanisms to move different sections of the seat.

Depending on its exact installation position, a seat motor can be responsible for functions such as:

• Forward / backward seat movement

• Seat height adjustment

• Seat base angle / tilt adjustment

• Backrest adjustment

• Other powered seat positioning functions

IMPORTANT: An electric BMW seat can contain multiple motors that look similar.

The numbers:

405019

P10155901

should therefore be compared directly with the motor being replaced.

ELECTRIC SEAT SYSTEM INFORMATION

When the occupant operates the seat adjustment switch, an electrical command is sent through the seat control system to the appropriate motor.

The motor converts electrical energy into mechanical movement, operating the relevant seat gearbox, spindle, cable or adjustment mechanism.

On vehicles equipped with electric memory seats, the adjustment system can also work with the seat electronics to move the seat to stored positions.

COMMON SYMPTOMS / REASONS FOR REPLACEMENT

Replacement may be required due to:

• One electric seat adjustment function not working

• Seat moves in one direction but not another

• Seat adjustment completely inoperative in one axis

• Motor operating intermittently

• Motor making abnormal noises

• Electric motor seized

• Internal motor failure

• Damaged electrical connection

• Damaged drive mechanism

• Existing motor damaged during seat repair

• Replacement during electric seat refurbishment

IMPORTANT DIAGNOSTIC INFORMATION

If only one movement of the electric seat has stopped working while the other adjustments continue to operate normally, the individual motor or associated mechanism may be at fault.

Before replacing the motor, check:

• Seat adjustment switch

• Seat control module / ECU

• Seat wiring loom

• Motor electrical connector

• Power and ground supply

• Mechanical adjustment mechanism

• Drive cables / spindle mechanism

• Seat rails for obstruction

• Relevant diagnostic fault codes

A motor that can be heard running without corresponding seat movement can indicate a problem with the mechanical drive mechanism rather than the electric motor itself.

PART NUMBER INFORMATION

Identification markings supplied for this motor:

405019

P10155901

These should be treated as the primary identification references for this particular component unless a separate BMW OE label/number is visible on the motor.

Do not substitute a different E92 seat motor purely because it looks visually similar.

BMW electric seat assemblies can contain several similar-looking motors with different gearing, mounting arrangements or adjustment functions.

INSTALLATION

The motor is installed within the front electric seat frame / adjustment mechanism.

Installation may require:

• Removal of the front seat

• Removal of seat side trim

• Access to the underside of the seat frame

• Disconnection of the motor electrical connector

• Removal of the associated drive mechanism or mounting hardware

Correct routing and positioning of wiring must be maintained during installation.

SRS / SAFETY INFORMATION

BMW front seats can contain components connected to the vehicle’s:

• Side airbag system

• Seat belt pretensioner

• Occupancy detection system

• SRS wiring

• Seat position / electrical systems

The battery should be disconnected and the appropriate BMW repair procedure followed before disconnecting seat electrical components.

Professional installation is recommended.

PROGRAMMING / CODING

Programming Required: Normally No

Coding Required: Normally No

Replacing an individual electric seat motor with the correct like-for-like component normally does not require coding.

However, diagnosis or seat-position initialisation may be required in some configurations following repair.

Retrofitting a different type of electric or memory seat is a separate procedure and can require additional wiring, control modules and coding.

IMPORTANT COMPATIBILITY NOTE

Before ordering, please compare:

405019

P10155901

Also check:

• Front right seat application

• Motor body/design

• Electrical connector

• Connector pin configuration

• Motor mounting points

• Drive connection

• Seat type

• Adjustment function

• Vehicle production date

• Listing photographs

Matching the E92 model alone is not sufficient to guarantee compatibility.

BMW fitted several different electric motors within the same seat assembly, so the numbers, mounting arrangement and adjustment function should match the original motor wherever possible.

CONDITION

Used Genuine/OEM BMW Part.

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

Please inspect all listing photographs carefully for the exact motor, connector, mounting points, identification numbers and overall condition.

Ideal genuine/OEM replacement for repairing a faulty front right electric seat adjustment system on a compatible BMW 3 Series E92 Coupé.
