This problem is due to few possibilities, it all has to be tested, before confirming the problem.---------
The problem can be with pump,relay, strut or with the sensor.--------
The pump is located in the front drivers side bumper.------
The suspension pump relay is just outside of the fuse box. If you looking at the fuse box with cover removed, and you are standing at the driver side front tire area, its on the lower right side corner (black relay) just outside the fuse box.----------
The Ride Height Sensor ( Part 0025426918 )
And Suspension Strut. Front Suspension - Shock Absorber - with active Suspension - Left ( Part 2113205513 ).--------- The airmatic needs to be inspected.-------
--------
Also for the front
AUX battery on a 2005 E500 Mercedes Benz,It's on the passenger side at the back, between the shock tower and the firewall. You have to remove the duct to get to it.----------
-------
This all needs to be inspected by your local MB dealer.In some cases all this possibilities checked out ok, and only computer needs to be reset.This also has to be done by reset tool from MB.-------
But proper testing has to be done.In this " front end too low" or car to low " message car starts fine, but this problem later on causes noise from suspension and later on suspension related problem starts.Its advisable to get all the mentioned possibilities inspected.---- The parts are costly, so getting it confirmed by scan too from dealer is advisable.--------
This will help.Thanks.Helpmech.
Most likely a leak in the air suspension causing the compreesor to create a battery drainage
