Air Suspension Height Sensor and Compressor Failure
The Discovery 5's electronic air suspension (EAS) system experiences height sensor drift and compressor failure. The vehicle sits unevenly, leans to one side, or fails to raise from access height. A 'Suspension Fault' message appears, and the system defaults to normal height only. The height sensors corrode at their lower mounting points due to water and road debris exposure.
Replace the faulty height sensors and recalibrate the suspension system with the dealer diagnostic tool. If the compressor has failed, replace it along with the air dryer. A full system leak-down test should be performed to rule out air strut or line leaks. JLR TSB LTB00680 covers EAS diagnostics.
Est. Cost: $200 - $500 per sensor / $1,500 - $3,000 (compressor)InControl Touch Pro Infotainment Black Screen and Slow Response
The InControl Touch Pro system goes to a black screen or becomes extremely slow and unresponsive. The navigation crashes, Bluetooth phone calls drop, and the backup camera becomes unavailable. The system may take 2-3 minutes to fully boot on startup. Some owners report the system rebooting spontaneously while driving.
A dealer software update resolves many stability issues. The SSD storage in the infotainment module can become fragmented, and a full system reinstallation may be needed. If the hardware has failed, the infotainment control module must be replaced. TSB LTB00671 provides a diagnostic flow.
Est. Cost: $0 - $200 (software) / $1,500 - $3,500 (module replacement)3.0L Td6 Diesel EGR Cooler and DPF Issues
The 3.0L Td6 diesel engine's exhaust gas recirculation (EGR) cooler can develop internal leaks, allowing coolant into the intake manifold. Simultaneously, the diesel particulate filter (DPF) clogs with excessive short-trip driving. Symptoms include white exhaust smoke, loss of coolant, rough running, and the engine entering limp mode with reduced power.
Replace the EGR cooler if an internal leak is confirmed through a combustion gas test of the coolant. A DPF forced regeneration should be attempted first; if the DPF is beyond recovery, it must be replaced. JLR recall 18V-591 addresses EGR cooler failures on certain Td6 engines.
Est. Cost: $1,200 - $3,000 (EGR cooler) / $2,500 - $5,000 (DPF replacement)Wading Sensor and Door Seal Water Intrusion
The Discovery's wading depth sensors (mounted low on the body) malfunction or provide false readings. Additionally, door seals at the bottom of the front and rear doors allow water to enter the footwells during heavy rain or car washes. Owners find damp carpets and, in severe cases, standing water in the passenger footwell.
Replace the faulty wading depth sensors and ensure the rubber grommets on the lower body harness connectors are properly sealed. Door seals should be replaced if they are compressed or cracked. The footwells must be dried thoroughly to prevent corrosion and mold. JLR TSB LTB00695 addresses body water intrusion.
Est. Cost: $300 - $600 (sensors) / $200 - $500 (door seals) / $500 - $1,500 (water damage remediation)Steering Column Lock Module Failure — No Start
The electronic steering column lock (SCL) module fails, preventing the vehicle from starting. The key fob is recognized, the dashboard illuminates, but the engine will not crank and a 'Steering Column Lock Fault' message is displayed. The issue is caused by an internal microswitch failure in the SCL module and can strand owners without warning.
Replace the electronic steering column lock module. The module must be programmed to the vehicle and the key fobs re-synced using the JLR diagnostic tool. A mobile JLR technician can perform the repair roadside in some cases. JLR issued recall N546 for SCL failures on certain Discovery models.
Est. Cost: $500 - $1,2002 NHTSA safety recalls for the 2021 Land Rover Discovery. Check your VIN at NHTSA.gov
