Land Rover Discovery Sport Electric Steering Rack Repair
L550 (2014-on), confirmed electric-rack applications. Repair, reconditioning, replacement supply and workshop fitting for private, garage and trade customers.
Land Rover Discovery Sport Electric Steering Rack Specialists
Pro Power Steering assesses and reconditions applicable Land Rover Discovery Sport electric power-assisted steering racks. We can repair the original unit where suitable, supply a correctly identified reconditioned replacement, or discuss supply and fitting at our workshop.
JLR can use several rack families within one model and year. Right-hand-drive specification, build date, chassis platform, steering equipment, software level and every suffix on the original label matter. We never confirm compatibility from the model name or a shortened number alone.
Electric rack only: Freelander and earlier Land Rover hydraulic racks are not covered by this electric-rack page. They require separate hydraulic steering identification.
Generation and Steering-System Coverage
L550 (2014-on), confirmed electric-rack applications. Coverage is subject to physical identification. Mild-hybrid, plug-in hybrid, performance and driver-assistance variants can use different racks or software, even when the body shape looks identical.
Repair your original rack
We assess the original electric rack, symptoms and diagnostic record before confirming whether repair or reconditioning is suitable.
Replacement rack supply
Correctly matched reconditioned units may be available subject to stock, exchange conditions and complete identification.
Supply and fitting
Private customers, garages, workshops and trade partners can ask about supply and professional fitting.
Calibration and alignment
Programming, initialisation, steering-angle calibration and wheel alignment requirements depend on the exact vehicle and unit.
Land Rover Discovery Sport Rack Numbers and Reference Families
These are reference families seen in verified reference data and on relevant units; they help identification but do not prove interchangeability. A complete VIN and original rack label must be checked before ordering or repair.
Later L550 rack families
F2 / J2 families, including , used on relevant later production applications.
Latest identified family
LPLA-labelled family including for applicable 2019-on right-hand-drive vehicles.
Identification rule
Discovery Sport racks vary with build date, drivetrain, steering equipment and suffix. Send every character from the original label; a shortened family code is not enough.
Important: Every digit and suffix matters. A shared reference family across two vehicles does not prove that the racks, electronics, software, mounting or steering ratio are interchangeable.
Common Land Rover Discovery Sport Electric Steering Faults
- Heavy steering or complete loss of assistance
- Intermittent assistance, especially after start-up
- Power steering warning on the instrument display
- Knocking, play, creaking or rack noise
- Notchy, uneven or binding steering
- Water ingress, corrosion or connector damage
- Warning after battery or suspension work
- Communication or supply-voltage DTCs
A steering warning does not automatically prove the rack is faulty. Battery voltage, charging, power and earths, fuses, CAN wiring, connectors, steering column, suspension joints and alignment can influence symptoms.
Land Rover Discovery Sport EPS Fault Codes and Diagnosis
Send a full JLR-compatible scan showing the reporting module, complete DTC including suffix, current or historic status and freeze-frame details. Do not send only a dashboard message or a shortened code.
| Code or family | Possible meaning | Checks before rack replacement |
|---|---|---|
| B1304-16 | EPAS circuit voltage below threshold can accompany heavy steering or a warning. | Battery condition, cranking voltage, charging output, EPS supply, fuses and earths. |
| U3001-00 | Improper shutdown or power-interruption history in the steering control system. | Low-voltage history, connectors, related module codes and whether the code returns. |
| U0131-00 | Lost communication with the power steering control module. | Identify which module reported it; test PSCM power, earth, network wiring and connectors. |
| U0001-87 / -88 | High-speed CAN communication or message-validity concern. | Complete network scan and wiring diagnosis; do not condemn the rack from one communication code. |
Safety first: If assistance is lost, steering effort can increase substantially. Stop using the vehicle if it is unsafe and arrange professional diagnosis or recovery.

Land Rover Discovery Sport Steering Rack FAQs
Does every Land Rover Discovery Sport use the same electric rack?
No. Rack family, suffix, steering ratio, electronics and software can vary by generation, build date and specification.
Will the replacement rack need programming?
Requirements vary. Some correctly matched units may need steering-angle calibration or end-stop learning; others can require coding, initialisation or software work.
Can garages and trade customers use this service?
Yes. We work with private customers, garages, workshops and resellers. Send complete identification before removing or ordering a unit.
Do the numbers listed guarantee compatibility?
No. They are identification aids. We must check the full label, suffix, VIN, build date and vehicle specification.
What warranty applies?
Warranty terms depend on the agreed repair or supplied unit. For trade or resale work, tell us when the unit is sold or fitted if that differs from the invoice date.
