The front axle level sensor (also known as ride-height or suspension level sensor) is a vehicle-height/position sensor mounted at the front suspension. It senses the instantaneous position/angle of the front suspension, via a short linkage/arm that connects to the control arm/strut area and sends that signal to the suspension/ride-control module. That data is used for front-axle lift control, active damping logic, stability control/DSC algorithms and headlight leveling. The two OEM part numbers are the left and right front sensors: 992.616.213.A and 992.616.214.A.

Why they should be replaced 

You should replace a front level sensor when it is failing, damaged, or giving incorrect readings that the car’s control modules detect. Typical symptoms that indicate a replacement is required: 

• Suspension / “ride height” warning or “front axle lift malfunction” message on the instrument cluster. 
• The front lift will not operate (won’t raise or won’t lower) or the car is stuck in a lift/stuck at minimum height. 
• Diagnostic trouble codes indicating a ride-height / level sensor fault (the suspension module reporting implausible or missing signals). (Use a Porsche-capable diagnostic tool to read these codes.) 
• Intermittent faults that clear after tapping the sensor/connector or faults that appear after exposure to water / road debris. 

Common failure modes / issues

·       Seized or broken linkage ball/socket joints — the little plastic/steel ball joints that connect the sensor lever to the control arm can corrode or seize, causing stuck or incorrect readings. This is often visible on inspection.

·       Water ingress / corroded connector — moisture in the sensor connector or wiring harness causes intermittent faults or total failure. Owners commonly report faults after heavy rain / pressure-washing.

·       Internal sensor failure — the sensing element (potentiometer or magnetic/Hall element inside) can fail electrically over time. After this, readings are wrong or no signal at all.

·       Wiring or ECU/module issues — sometimes the sensor is replaced but the issue was connector/wiring damage or a control module problem; always verify wiring/connector and live data.
