Rear Level Sensor For Land Rover Discovery 3 LR3 Range Rover Sport LR020159 RQH500052

Q1: Which vehicles does this fit? Land Rover LR3 / Discovery 3 (L319, 2005–2009) and Range Rover Sport (L320, 2006–2009) per the supplier table; catalog fitment: Discovery 2004–2009 and Range Rover Sport 2005–2013. Confirm the exact model and year by VIN.
Q2: What is this part exactly? A level sensor — it measures the ride height / suspension level and supplies the signal for air-suspension leveling and headlight levelling (range adjustment). It is NOT a damping unit — an electronic sensor (3-pin, D-shaped connector, with fastening material, for vehicles with air suspension).
Q3: Why are there 4 OE numbers? They are the same sensor's complete OE family: LR020159, LR020160, RQH500052, RQH500053 — all four verified in the same catalog OE list. Order by any of them.
Q4: Which side is this? Catalog data confirms Rear Axle Left (for OE LR020159). The rear right counterpart exists (paired article V48-72-0091) — confirm the side and number by VIN before ordering.
Q5: Does it fit only air-suspension vehicles? Yes — the catalog lists the spring type as for vehicles with air suspension (Discovery 3 / RRS with air ride; also relevant for headlight range adjustment). Confirm the equipment by VIN.
Q6: Warranty policy and shipping damage? 18-month warranty under normal use. For shipping damage, inspect within 48 hours of receipt and send photos/video — the seller arranges a replacement.
Q7: Service life and maintenance? Depends on road conditions. If the suspension-level warning or headlight-range fault appears, check the sensor, its connector and the link rod first; replace if the sensor signal is faulty.
Q8: Are aftermarket alternatives available? The interchange list for these OE numbers is available on request. Order by the exact OE number and confirm the model/year and side by VIN.
