Review on 🚘 High-Quality Air Suspension Compressor Pump for Mercedes Benz GL320/GL450/GL350/GL500/GL550 2007-2012 - OEM Compatible by Matt Welch

Replaced the front air shock which had been leaking for a while and after installation the 2012 GL450 would not rise to the normal ride height. Checked the existing pump and there was hardly any air movement. Replaced with this pump along with the filter and now the car starts normally. The only difference I can tell is that after the pump has stopped, there is a loud flushing noise at the pump inlet, as if air is momentarily escaping. The normal one did not make such noises, but this does not affect the functionality. **** Pump update died after 6 months
