Questions about this item

Does the 20-012900 compressor fit my 2007 Mercedes-Benz ML320 without extra parts?

The compressor is listed for the 2007-2009 ML320 and installs using the original mounting points and electrical connectors on that model.

Will the new compressor work with the original air springs and valve block on a 2010 GL350?

Yes, the unit is an OE-style replacement for the 2010-2012 GL350 and connects to the existing air lines and valve block without modification.

How can I confirm the compressor is running correctly after installation on a 2011 ML63 AMG?

Start the engine and watch the vehicle level; the compressor should build pressure and raise the suspension to the normal ride height within a few minutes.
