COMPATIBILITY

The 82148143 motor belongs to a Land Rover/JLR electric-seat motor family used across several related vehicle applications.

The donor application for this item is:

LAND ROVER DISCOVERY 4 / DISCOVERY IV L319

2010 Land Rover Discovery 4 L319

Front Right Seat

UK RHD – Driver / O/S

Potential Discovery 4 applications include selected:

• Discovery 4 2.7 TDV6 – 276DT

• Discovery 4 3.0 TDV6 – 306DT

• Discovery 4 3.0 SDV6 – 306DT

• Discovery 4 5.0 V8 Petrol – 508PN

• Discovery 4 / LR4 North American specification vehicles

Approximate Discovery 4 model range:

2009–2016

Fitment is dependent on the electric seat specification and exact motor installed, rather than engine size.

RANGE ROVER SPORT L320

Strong direct cross-application evidence exists for 82148143 on Range Rover Sport L320.

Documented examples include a:

2010 Range Rover Sport L320

3.0 Diesel

Right Seat

82148143

Potential L320 applications include selected:

• 2.7 TDV6

• 3.0 TDV6

• 3.6 TDV8

• 4.2 Supercharged V8

• 4.4 V8

• 5.0 V8

• 5.0 Supercharged V8

Approximate model range:

2005–2013

Exact seat mechanism and motor number must match.

RANGE ROVER L322

The 82148143 motor is also documented on selected Range Rover L322 electrically adjustable front-seat assemblies.

Potential applications include selected:

• Range Rover L322 diesel models

• Range Rover L322 petrol models

• Vogue / HSE specifications

• Electrically adjustable / memory-seat equipped vehicles

Compatibility remains dependent on the exact seat mechanism.

LAND ROVER FREELANDER 2 / LR2 L359

The exact 82148143 / 82148143-4 motor is independently documented as a Freelander 2 front seat adjustment drive motor.

Potential applications include selected:

• Freelander 2 2.2 TD4

• Freelander 2 2.2 SD4

• Freelander 2 3.2 i6 Petrol / LR2

• Electrically adjustable front-seat versions

Approximate model range:

2006–2014

The same number has been documented from both different seat positions across the wider Land Rover application range.

IMPORTANT SIDE INFORMATION

This particular motor was removed from:

FRONT RIGHT SEAT

On a UK RHD Discovery 4:

Front Right = Driver / O/S

However, 82148143 should not be treated as universally right-seat-only.

The same exact number is documented from:

• Right front seat – Range Rover Sport L320

• Front seat – Freelander 2

• Left front seat – LR2/Freelander 2

Therefore the physical motor itself can be used within different seat assemblies depending on the vehicle and seat mechanism.

For compatibility purposes, the 82148143 number and physical motor configuration are more important than Driver / Passenger wording.

TECHNICAL INFORMATION

The 82148143 is an electromechanical drive motor fitted within the powered front-seat assembly.

When the corresponding seat adjustment switch is operated, the vehicle supplies electrical power to the motor.

The motor converts electrical energy into rotational movement.

This movement is transferred through the associated seat drive mechanism, which may incorporate:

• Flexible drive shaft

• Drive cable

• Reduction gearbox

• Adjustment spindle

• Seat rail

• Seat frame linkage

• Mechanical adjuster

This allows the corresponding section of the seat to change position.

ELECTRIC SEAT SYSTEM INFORMATION

A Discovery 4 electrically adjustable front seat contains multiple individual motors and adjustment mechanisms.

Depending on vehicle specification, these can control:

• Forward / backward seat movement

• Seat height

• Front/rear cushion inclination

• Backrest recline

• Lumbar functions

• Other comfort adjustments

Higher-specification Discovery 4 seats can additionally incorporate:

• Driver memory

• Seat heating

• Seat ventilation depending on specification

• Seat control electronics

• Multiple electric adjustment motors

• Integrated SRS components

For this reason, not every electric motor inside a Discovery 4 seat is interchangeable.

MOTOR IDENTIFICATION

The primary identification number for this item is:

82148143

Also found as:

82148143-4

A related/cross-reference number appearing with this motor is:

404905

Before purchasing, compare all numbers visible on your original component wherever possible.

COMMON SYMPTOMS / REASONS FOR REPLACEMENT

• Electric seat adjustment not working

• One adjustment direction has stopped operating

• Seat stuck in one position

• Seat moves intermittently

• Adjustment unusually slow

• Electric motor seized

• Motor making abnormal noise

• Clicking or grinding during adjustment

• Internal motor failure

• Damaged motor connector

• Damaged drive mechanism

• Motor operates but seat does not move

• Seat repair/refurbishment

• Motor damaged during seat removal

IMPORTANT DIAGNOSTIC INFORMATION

A seat that does not move does not automatically mean the motor has failed.

Before replacing the motor, check:

• Seat adjustment switches

• Relevant fuses

• Power supply

• Ground connections

• Seat wiring harness

• Electrical connectors

• Seat control electronics

• Flexible drive cable/shaft

• Gearbox

• Adjustment spindle

• Seat rails

• Seat frame mechanism

• Mechanical obstruction

If you can hear the motor running but the seat does not move, the fault may be within the drive cable, gearbox, spindle or seat mechanism rather than the electric motor.

SEAT MEMORY / ELECTRONICS

Depending on trim level, the Discovery 4 can be equipped with an electronically controlled driver’s memory seat.

The complete system can involve:

• Seat adjustment switches

• Electric adjustment motors

• Seat wiring harness

• Memory functions

• Seat control electronics

• Vehicle communication network

• Mirror/seat position memory functions

The 82148143 motor itself is an actuator/drive motor, rather than the main programmable seat ECU.

INSTALLATION

Install the replacement motor in the same position and orientation as the original.

Before fitting, compare:

• 82148143 part number

• Motor body/casing

• Electrical connector

• Connector pin configuration

• Drive output

• Flexible shaft/cable connection

• Mounting points

• Motor orientation

• Position within the seat

After installation, test the appropriate seat adjustment through its full operating range.

The seat should move smoothly without:

• Binding

• Excessive resistance

• Clicking

• Grinding

• Uneven movement

PROGRAMMING / CODING

No programming or coding should normally be required for the 82148143 electric motor itself.

It is an electromechanical actuator controlled by the vehicle’s existing seat electrical system.

If the seat control ECU/module is also replaced, separate diagnostic configuration may be required.

IMPORTANT COMPATIBILITY NOTE

Land Rover used several different electric motors within the same front-seat assembly.

Do not order this motor solely because your vehicle is a:

• Discovery 4 L319

• Range Rover Sport L320

• Range Rover L322

• Freelander 2 / LR2 L359

Please match:

82148143

and where applicable:

82148143-4

404905

Also compare:

• Motor casing

• Electrical connector

• Number of pins

• Drive output

• Drive cable/shaft fitting

• Mounting arrangement

• Motor position within the seat

• Seat adjustment mechanism

Matching 82148143 and the complete physical configuration against your original motor is the safest method of confirming compatibility.

CONDITION

Genuine used Land Rover OEM electric front-seat adjustment motor.

Removed from:

2010 Land Rover Discovery 4 L319

Front Right Seat

UK RHD – Driver / O/S

Normal signs of previous installation, use, removal and storage may be present.

Please inspect all listing photographs carefully and compare the part number, connector, drive fitting and mounting points against your original component.

Ideal genuine replacement for a faulty, seized or damaged electric seat adjustment motor on compatible Discovery 4 L319, Range Rover Sport L320, Range Rover L322 and Freelander 2/LR2 applications where 82148143 and the physical seat mechanism match the original motor.
