Level Sensor Front Left For Land Rover Discovery 3 LR3 L319 LR020155 LR019137 RQH500071

Q1: Which vehicles does this fit? Land Rover Discovery 3 / LR3 (L319, 2004–2009) per the supplier table; catalog fitment: Discovery 2004–2009. 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, for vehicles with air suspension).

Q3: Why are there 6 OE numbers? They are the same sensor's complete OE family: LR020155, LR020156, LR019137, RQH500070, RQH500071, AH223C097AC — all six verified in the same catalog OE list. AH223C097AC is the Ford-format number (AH22 3C097 AC / AH22-3C097-AC). Order by any of them.

Q4: Which side is this? Catalog data confirms Front Axle Left. A right-side counterpart exists (paired article, e.g. ECX-LR-007) — 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 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.
