Mounted to the rear suspension assembly, the level sensor continuously monitors suspension movement and transmits real-time ride height information to the vehicle's control modules. This data allows systems such as air suspension, adaptive chassis control and automatic headlamp levelling to make precise adjustments, ensuring optimum vehicle balance, handling stability and driving comfort.
What This Product Does:
- Monitors rear axle ride height and suspension position.
- Provides real-time data to chassis and suspension control systems.
- Supports air suspension and ride height adjustment functions.
- Assists automatic vehicle levelling systems.
- Provides input for automatic headlamp levelling.
- Helps maintain correct vehicle stance and balance.
- Contributes to ride comfort and handling stability.
- Supports the operation of advanced electronic suspension systems.
Symptoms Of Wear Or Failure:
- Suspension warning lights illuminated on the dashboard.
- Air suspension fault messages.
- Uneven vehicle ride height.
- Rear of the vehicle sitting too high or too low.
- Vehicle leaning to one side.
- Incorrect headlamp alignment.
- Suspension failing to adjust ride height correctly.
- Fault codes relating to level sensors or chassis systems.
- Reduced ride comfort and handling performance.
- Physical damage or corrosion of the sensor linkage.
Why Replacement Matters:
- Rear axle level sensors operate in a harsh environment where they are exposed to water, dirt, road salt, vibration and constant suspension movement. Over time, the sensor mechanism, linkage arms and electrical connections can become worn, corroded or damaged, resulting in inaccurate ride height measurements.
- A faulty level sensor can prevent the suspension system from maintaining the correct vehicle height and balance, affecting handling, ride quality and tyre wear. It may also compromise automatic headlamp levelling and place additional strain on air suspension compressors and control components.
- Replacing a worn or defective rear axle level sensor restores accurate ride height monitoring and ensures proper operation of the vehicle's suspension and levelling systems. A genuine Porsche replacement provides precise calibration, factory-correct fitment and long-term reliability, helping preserve the comfort, safety and performance characteristics engineered into your Porsche.

OE Match air suspension compressor for Porsche 95B Macan models. This replacement compressor helps generate and supply compressed air for the air suspension system, supporting correct ride height adjustment and suspension operation.
Disclaimer: Please note to change suspension compressor is not simple DIY replacement job. To complete the process you need access to PIWIS software and Nitrogen grade 5 dry gas fill up station. If you just replace the compressor and don't follow the correct procedures you will damage the new unit.
Fits:
Porsche 95B.1 Macan 2014 - 2018 (1BK)
Porsche 95B.2 Macan - 2019 Onwards (1BK)
* option code: 1BK - Air suspension with levelling system and height adjustment (PASM)
The air suspension compressor produces compressed air for the suspension system. This air is used to raise, lower, and maintain the vehicle’s ride height through the air suspension valve block, reservoir, and air spring system.
Functions
• Replaces the air suspension compressor
• Supplies compressed air to the air suspension system
• Supports ride height adjustment
• Helps maintain correct vehicle level
• Assists with smooth air suspension operation
• Suitable for air suspension fault repair and diagnosis
• OE Match replacement for Porsche Macan air suspension service.
Why Replace This Part?
Air suspension compressors can weaken or fail due to age, moisture contamination, air leaks, overworking, worn internal components, electrical faults, or blocked intake filters. A failing compressor may cause slow ride height adjustment, suspension warning messages, compressor noise, uneven vehicle height, or failure to raise the vehicle. Replacing the compressor helps restore reliable air pressure supply and correct suspension operation.
When to Replace This Part
• Air suspension warning messages are present
• The vehicle raises slowly or will not raise
• Compressor runs too often, too long, or not at all
• Ride height adjustment is uneven or inconsistent
• Compressor is noisy, weak, seized, or failed
• Air suspension pressure faults are present
• Air suspension diagnostics indicate compressor failure.
Where it fits on the car
This compressor fits within the air suspension air supply system on Porsche 95B Macan models. Exact location can vary depending on model year and suspension layout.
