Fix Sagging Suspension | 2008–2016 Mercedes GL550 AirBag Leak Test and Replacement

Описание: In this video, we walk you step-by-step through a rear air spring replacement on a 2008–2016 Mercedes-Benz GL550 (X164/X166 platform). If your GL550 is sagging in the rear, sitting uneven overnight, or showing an air suspension warning, this repair is for you.

Before replacing parts, we performed a smoke test on the air suspension system to accurately locate the leak. Using a smoke machine, we pressurized the system and confirmed the rear air spring was leaking — saving time and preventing unnecessary parts replacement. Proper diagnosis is key when dealing with Mercedes AIRMATIC systems.
