Description
Front and rear body height sensor for Citroen C5 and C5 X7
Used part that may be rusty but guaranteed functional
Connecting ball joints shown in photos are not included in the delivery
Product Overview
This height sensor (also called suspension level sensor) is designed for the front and rear suspension of Citroen C5 models including the C5 X7. It measures body ride height and feeds the signal to the suspension control system to maintain correct ride level and damping. Ideal for professional workshops and experienced DIY mechanics looking to replace a faulty sensor using the original part numbers 9641247280 / 5273J4.
Function
The sensor converts the mechanical position of the suspension linkage into an electrical signal for the vehicle’s control modules. The information is used to adjust hydraulic/air suspension settings or to trigger warnings when ride height is outside specified limits. A correctly functioning sensor ensures stable handling, correct headlamp leveling (if applicable) and proper suspension response.
Fitment And Compatibility
Compatible With: Citroen C5, Citroen C5 X7 (front and rear). Always check the part number against the vehicle’s required reference before installation. Note: Connecting ball joints shown in images are not included with the sensor and must be reused or ordered separately.

Common Failure Causes
Height sensors typically fail due to corrosion at electrical contacts or mechanical wear in the linkage and ball joints. Moisture ingress, road salt and mechanical impact (stones, curbs) accelerate deterioration. Lossy or intermittent signals cause incorrect ride height readings, warning lamps, uneven ride or degraded suspension performance.
Replacement Interval And Signs
There is no fixed replacement interval; lifespan depends on driving conditions and environment. Replace the sensor if you observe suspension warning lights, irregular ride height, uneven vehicle stance, or if diagnostics report implausible height sensor values. Visual signs of rust or damaged connector housings also indicate replacement is advisable.
Installation Recommendations
– Prepare the vehicle by safely supporting it and relieving load on the suspension so the linkage is accessible.
– Before starting work, disconnect the battery to prevent short circuits and avoid damage to the vehicle electronics.
– Remove the old sensor from its mounting and carefully detach electrical connector; inspect connector pins for corrosion.
– Fit the replacement sensor to the same mounting points, reuse correct ball joints or replace them if worn, and ensure linkage moves freely without binding.
– Reconnect the electrical connector ensuring secure contact and routing away from heat and moving parts.
– After installation, perform a basic diagnostic or ride-height check using workshop equipment to confirm correct readings and sensor operation.
Why Choose This Part
Original part numbers ensure direct fitment and compatibility with Citroen C5 X7 suspension systems. This used unit may show external corrosion but is supplied with a guarantee of functionality, representing a cost-effective solution for repairs when an OEM-equivalent part is required.
Notes
Connecting ball joints displayed in product images are not included. For a durable repair, consider replacing worn linkage joints and securing connectors against moisture.
