AMK Air Suspension Compressor Air Relief Valve – Mercedes GL / GLS / ML W164 | OEM 1643200104
The air relief valve on the AMK air suspension compressor for Mercedes GL, GLS, and ML W164 controls pressure release when the compressor stops. A faulty relief valve causes the compressor to vent pressure incorrectly — resulting in slow suspension leveling, fault codes, and continuously running compressor. This direct replacement valve restores correct pressure regulation.
Fits OEM #164320120480.
