COMPATIBILITY

The exact 404.964 / 368605 motor has documented applications across several Land Rover platforms.

Direct fitment evidence includes:

LAND ROVER DISCOVERY 4 / DISCOVERY IV L319 – 2009–2016+

Confirmed on Discovery 4 L319 Front Right Seat applications.

Potential applications include selected:

• 2.7 TDV6 – 276DT – 2.7 Diesel

• 3.0 TDV6 – 306DT – 3.0 Diesel

• 3.0 SDV6 – 306DT – 3.0 Diesel

• Other Discovery 4 derivatives equipped with the corresponding electric front-seat mechanism

A documented Discovery IV L319 application identifies 404964 / 368605 specifically as the Front Right Seat Control Motor on a 3.0 SDV6 306DT vehicle.

LAND ROVER DISCOVERY 3 / DISCOVERY III L319 – 2004–2009

The same 404964 / 368605 motor is also documented on Discovery 3 electric front seats.

Potential applications include:

• Discovery 3 2.7 TDV6 – 276DT

• Selected petrol Discovery 3 models with corresponding powered front seats

• HSE and other electric-seat equipped specifications

Used-parts data documents the exact 404964 / 368605 motor on Discovery III L319 applications.

RANGE ROVER SPORT L320 – APPROX. 2005–2013

Strong cross-model compatibility exists with the first-generation Range Rover Sport L320.

Documented applications include selected:

• 2.7 TDV6

• 3.0 TDV6 – 306DT

• 3.6 TDV8 – 368DT

• 4.2 Supercharged V8

• 4.4 V8

• 5.0 V8 – configuration dependent

• 5.0 Supercharged V8 – configuration dependent

The exact 404.964 / 368605 motor is documented on Range Rover Sport front-seat applications, including Front Right Seat installations.

RANGE ROVER L322

The 404964 / 368605 motor is also documented on selected Range Rover L322 powered front-seat assemblies.

Known applications include selected:

• 3.6 TDV8 – 368DT

• Other L322 derivatives using the corresponding Valeo seat mechanism

IMPORTANT: Engine size is not the main factor determining compatibility.

This component is part of the seat mechanism, so compatibility depends primarily on:

• Motor number

• Seat frame

• Electric seat specification

• Motor position

• Drive mechanism

• Electrical connector

• Mounting arrangement

FRONT RIGHT / DRIVER / PASSENGER INFORMATION

This particular donor application is:

FRONT RIGHT SEAT

For a UK RHD Discovery 4:

Front Right = Driver / O/S

For an LHD vehicle:

Front Right = Passenger Side

For international buyers, Front Right is therefore the most accurate physical position.

IMPORTANT CROSS-SIDE INFORMATION

The 404.964 / 368605 motor is documented in used-parts catalogues on more than one seat-side application.

For example, the same exact number can be found advertised from:

• Discovery 4 Front Right seats

• Discovery 3 Front Left seats

• Range Rover Sport Front Right seats

• Other Land Rover front-seat assemblies

This suggests the motor itself can be used in different seat assemblies depending on the particular seat mechanism.

Therefore, 404.964 / 368605 should be used as the primary compatibility identifier rather than relying solely on Driver / Passenger wording.

TECHNICAL INFORMATION

The Valeo 404.964 is an electromechanical drive motor forming part of the powered front-seat adjustment mechanism.

When the appropriate seat adjustment control is operated, electrical power is supplied to the motor.

The motor converts this electrical energy into rotational movement.

Depending on its installation within the seat, the movement can be transferred through:

• Drive cable

• Flexible shaft

• Reduction gearbox

• Adjustment spindle

• Seat rail

• Seat frame linkage

This allows the corresponding part of the seat assembly to move.

ELECTRIC SEAT SYSTEM INFORMATION

Discovery 4 electrically adjustable front seats can contain several separate adjustment motors.

Depending on specification, electric adjustment functions can include:

• Forward / backward seat movement

• Seat height adjustment

• Seat base tilt / inclination

• Backrest recline adjustment

• Lumbar adjustment

• Memory seat functions

• Additional comfort adjustments depending on specification

Therefore, a Discovery 4 front seat can contain multiple motors which may look similar but carry different numbers.

DO NOT identify compatibility solely by appearance.

The number 404.964 / 368605 should be compared with the original motor.

COMMON SYMPTOMS / REASONS FOR REPLACEMENT

• Electric seat does not move

• One seat adjustment function has stopped working

• Seat stuck in one position

• Seat adjustment works intermittently

• Seat movement unusually slow

• Motor making unusual noise

• Motor seized

• Internal motor failure

• Damaged electrical connector

• Damaged drive mechanism

• Motor runs but seat does not move

• Seat frame repair requiring replacement motor

• Damage during seat removal

• Replacement during electric seat refurbishment

IMPORTANT DIAGNOSTIC INFORMATION

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

Before replacing the motor, check:

• Electric seat switches

• Seat fuses

• Power supply

• Ground connections

• Seat wiring harness

• Electrical connectors

• Seat control electronics

• Drive cable / flexible shaft

• Reduction gearing

• Seat adjustment spindle

• Seat rails

• Seat frame mechanism

• Mechanical obstruction

If the motor can be heard operating but the seat does not move, carefully inspect the drive cable, gearbox and mechanical seat mechanism before replacing the motor.

SEAT MEMORY / ELECTRONIC SYSTEM

Depending on trim level, Discovery 4 front seats can incorporate memory and other electronically controlled functions.

The complete system can involve:

• Seat adjustment switches

• Individual seat motors

• Seat wiring harness

• Memory-seat electronics

• Vehicle electrical network

• Driver-seat memory functions

• Mirror/steering memory integration depending on specification

The 404.964 / 368605 motor itself is an actuator, rather than the main seat control ECU.

INSTALLATION

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

Before installation compare:

• 404.964 / 404964 number

• 368605 reference

• Motor casing

• Electrical connector

• Connector pin configuration

• Drive output

• Shaft/cable fitting

• Mounting points

• Installation orientation

After installation, operate the relevant seat adjustment through its full range.

Movement should be smooth and free from:

• Binding

• Excessive resistance

• Clicking

• Grinding

• Uneven seat movement

PROGRAMMING / CODING

The 404.964 / 368605 electric motor itself should not normally require programming or coding.

It is an electromechanical actuator operated by the existing seat electrical/control system.

If a seat ECU, memory module or other electronic control component is replaced at the same time, separate diagnostic configuration may be necessary.

IMPORTANT COMPATIBILITY NOTE

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

Do not purchase solely because the vehicle is a:

• Discovery 3

• Discovery 4

• Range Rover Sport

• Range Rover

Please match the original motor number:

404.964

404964

368605

Also compare:

• Motor shape

• Electrical connector

• Connector pins

• Drive shaft connection

• Gear/drive output

• Mounting arrangement

• Position within seat

• Seat adjustment mechanism

Matching 404.964 / 368605 and the physical configuration with the original motor is the safest method of confirming compatibility.

CONDITION

Genuine used Land Rover / Valeo OEM front electric seat adjustment motor.

Removed from a:

2010 Land Rover Discovery 4 L319

Front Right Seat

UK RHD – Driver / O/S

As a used component, normal signs of previous installation, use, removal and storage may be present.

Please inspect all listing photographs carefully and compare the 404.964 / 368605 number, connector, drive connection and mounting arrangement with your original motor.

Ideal genuine replacement for a faulty or seized powered front-seat adjustment motor on compatible Land Rover Discovery 3 L319, Discovery 4 L319, Range Rover Sport L320 and selected Range Rover L322 applications where Valeo 404.964 / 368605 and the physical seat mechanism match the original component.
