Detailed Description

FCS HS004 is a suspension ride height sensor used on rear air suspension systems to report vehicle position to the suspension control system. It is listed for 2003-2012 Maybach 57 and 62, 2000-2006 Mercedes-Benz S430 and S500 with air suspension, 2006 Mercedes-Benz S350 with air suspension, and select rear E-Class and CLS-Class applications. If you are replacing a rear ride height sensor on a Mercedes-Benz E320, E500, E55 AMG, CLS500, or CLS55 AMG, verify the VIN breakpoints and notes shown in the fitment data before ordering. This part number, HS004, is also referenced for the same rear suspension applications across these vehicles.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Incorrect rear ride height readings
• Suspension warning messages related to leveling control
• Uneven rear stance on air suspension vehicles
• Delayed or inconsistent suspension height response
• Faults caused by a worn or inaccurate rear sensor

Installation Notes and Tips

Confirm the vehicle’s year, model, rear position, and VIN breakpoint before installation. This sensor is listed only for rear applications, and several Mercedes-Benz listings require specific VIN cutoffs or air suspension equipment. Compare the original sensor location and connector style to the existing part before replacement.

Quality Assurance

FCS offers this suspension sensor as a cataloged replacement part for the listed rear applications. Verify fitment against the vehicle identification number and suspension configuration to ensure correct selection.
