Where is the Mercedes-Benz Y52Y2 solenoid valve located?

Mercedes-Benz Y52Y2 solenoid valve is located at the bottom of the shock absorber, shaped like a cylinder with control wires and a plug. Solenoid valve working principle: The solenoid valve has a sealed chamber with through holes at different positions, each connected to different oil pipes. In the middle of the chamber is a piston, with electromagnets on both sides. The valve body is attracted to whichever side's electromagnet coil is energized, controlling the movement of the valve body to open or close different oil discharge holes. The oil inlet hole is normally open, allowing hydraulic oil to enter different discharge pipes, then using oil pressure to push the piston of the oil cylinder. The piston drives the piston rod, which in turn drives the mechanical device. Installation precautions: During installation, ensure the arrow on the valve body aligns with the medium flow direction. Do not install in areas with direct water dripping or splashing. The solenoid valve should be installed vertically upward; it should operate normally within a power supply voltage fluctuation range of ±15% of the rated voltage.
In my experience, the solenoid valve position in Mercedes-Benz cars is quite important. The y52y2 model sounds like a component in the automatic transmission. You can directly look below the engine compartment, usually near the transmission control valve body—that's the core area of the fluid system. The solenoid valve is responsible for switching hydraulic oil to precisely control gear shifts. If it malfunctions, the car may experience jerky shifts or slippage, affecting driving stability. I recommend regular maintenance checks rather than waiting for major failures, as it involves safety. You can do a preliminary inspection by opening the hood, but it's more reliable to have a professional mechanic test the wiring with a multimeter, especially for older cars prone to wiring issues due to aging. Addressing it early can save you from future troubles.
