This is a brand‑new aftermarket compressor from maXpeedingrods manufactured in China. It is marketed as matching original quality and performance, but it is not a Mercedes‑branded OEM unit.
The product description states that instruction is not included. Package contents and included hardware can vary—contact the seller to confirm what is shipped with the unit.
Professional installation is recommended. Air suspension systems are safety‑critical and can require specific tools, proper mounting, leak testing and vehicle relearning/leveling procedures.
Procedures vary by vehicle. Many Mercedes air suspension replacements require a system bleed, leveling/relearn or diagnostic steps with a scan tool. Plan to have the vehicle checked with appropriate diagnostic equipment after installation.
Common signs include persistent suspension sag, unequal ride height, compressor running continuously or loudly, suspension warning messages, or failure to inflate after startup.
The product carries a 2‑year warranty as stated in the description. For warranty claims, contact the seller or retailer for details on coverage and required proof of purchase.
The listing states it is made of high‑quality components and 'equals the original quality.' As an aftermarket replacement, fit and performance are intended to match OEM, but differences can exist—check seller reviews and warranty terms.
The unit is manufactured in China.
Return and refund policies are set by the seller or marketplace. Contact the seller directly to confirm their return window, restocking fees (if any), and the procedure for defective items.
Verify your vehicle model, production year and platform (e.g., GL‑Class X166) and compare the OEM part number(s). If uncertain, provide your VIN to the seller or consult a dealer/repair shop to confirm fitment.
