Hi, I have a 2003 e500 and a black hose from my suspension compressor broke and can't find where it was connected to. Any place where I could find schematics of those hoses connections?

Could be the codes, but most likely it may need to be re set because the battery was disconnected. Here is a great solution for if you ever have to remove your battery. Go to radio shack or any other place that sells a cigarette adapter, you just need the cigarette adapter and a couple of inches of wire sticking out. Strip the red and black wires and buy a 9 volt battery adapter. connect the two together red to red and black to black. plug it into your cigarette lighter socket and then anytime you have to remove the battery from you vehicle you will never lose any memory from the vehicles memory.
The easiest fix is to hook up a scanner on the suspension test plug. This will give you a test to each sensor. Some models may even record a history of performance.
Underneath the car, someone can use soapy water and spray the air lines and suspension bags to test for leaks. There are venting solenoids on each wheel to level the car and a Master solenoid called a "dump" valve to release all of the air
The system is tied into the doorjam and trunklid switches which must be closed to allow the system to work. Escaping air should be easy enough to find.
Hi Jose: The first place to start is to have Ride Control Module scanned for trouble codes, this requires a high end scan tool. Most common problem is the air compressor in the rear or a height sensor. Here is how the system works.
Automatic Level Control Description and Operation The RTD system is bi-state real time damping system. The Suspension Control module controls the suspension damper solenoids and suspension position sensors, along with parts of the automatic level control (ALC) system and electronic variable orifice (EVO) power steering system.
The Automatic Level Control system consists of the following: • Suspension Control Module • Compressor/Leveling Module - Air Pressure Sensor - Exhaust Solenoid • Compressor Motor Relay
The objective of the Automatic Level Control System is to provide constant ride height at all load conditions. The Suspension Control module monitors body-to-wheel height, and vehicle speed.
The Suspension Control module will use the rear body-to-wheel displacements and vehicle speed inputs to keep the rear trim height of the vehicle at its desired level.
The electronic suspension control (ESC) system is bi-state real time damping system. The ESC module controls the suspension damper solenoids and suspension position sensors, along with parts of the automatic level control (ALC) system, if 1500 series.
The ESC system consists of the following: • The ESC module • The compressor/leveling module, if 1500 series - The air pressure sensor, if 1500 series - The exhaust solenoid, if 1500 series • The compressor motor relay, if 1500 series • The steering handwheel speed/position sensor • The suspension damper solenoids • The suspension position sensors

Air suspensions on Lincolns...the bags are good for about 8 years, and this is 2011, soooo...but, there are a few things you can try. When you start it, do you hear the compressor running? If not, check the fuses and relay for the compressor, and there is a shut-off switch and reset button in the rear (check your owners manual) that may have tripped-try resetting it to see if that is all that is wrong. Is it down on all four corners, or just the front/back? All four probably is a little more involved, but if it is just one end, it is usually a damaged bag (cracks in the folds), an open soilenoid, or a timed-out compressor. If there is an air ride light on while the car is running, it is almost always an issue with the compressor itself.
the little orange or red ring around the air hose whare it goes in compressor, must be pushed in while pulling out on air line. a small flathead screwdriver works fine
Depends on how you want to spend your money. On multiple car repairs....or the funner things in life. Do a Mercedes E500 Suspension Conversion and do away with those expensive suspension repairs forever! I'd say this falls in the..."looks cool...rides like crap" category.
