| Fix | Procedure | Success Rate | |-----|-----------|---------------| | | Replace the complete air suspension valve manifold (Land Rover part numbers: LR134160, LR110837, LR156389 depending on model). Perform calibration/height reset. | 80% | | 2. Module firmware update | Reprogram Ride Level Control Module using JLR-approved software (if TSB JTB00518 or similar applies). | 10% | | 3. Repair corroded connector | Clean terminals, apply dielectric grease, replace damaged pins in harness side. | 5% | | 4. Replace suspension control module (if integrated separately from valve block – earlier models). | Module replacement + parameter restoration via SDD. | 5% |

Remove the display module (follow workshop manual – typically 4 Torx screws behind a trim bezel). Inspect vents for dust. Connect a 5V power supply directly to the fan connector. No spin = fan failure.
