Question about 2005 Mercedes-Benz Mercedes Benz E320 Cdi
I need to find a wiring diagram for a 2000 mercedes e320 cdi for the central locking vacuum pump to troubleshoot my system errors can you please advise? thanks
that appears to be a camshaft position sensor performance code. you can start by checking to see if the sensor is working properly, re-check and make sure that the harness is ok by checking the resistance through the harness if all looks well there make sure the computer has the latest software on it by having it scanned at your local dealer. also you can check the reluctor wheel on the camshaft for damage or debris in the way of the sensor.
hope this helps!

neto 190D: You are asking about a vacuum diaphragm?
I'm going to take a WAG.. Your engine won't shut
down with the key?
If so, he is the way you find out:
In your injection pump, the vacuum diaphragm which kills the engine is the one which has the fitting pointing parallel to the ground.
The vacuum line which serves it is a brown/blue
To check the system, first check for vacuum in the line. Run the engine for a minute or so. Cap off the brown/blue line.
Turn the ignition switch off and then with hose in hand, uncap it and you should hear a hissing sound. If you have a vacuum guage, obviously, use it for the test, you need a minimum of 10 inches to kill it.
To test the pump diaphragm, you can rig a vacuum line to a known vacuum source close to the main "T". Run the engine and with the line connected to the diaphragm, connect it to the good vacuum source, if it kill the engine, the diaphragm is good. If you have a hand vacuum pump it would be more ideal, because you could check the diaphragm for small leaks.
If the diaphragm is bad, it is easy to replace on the pump.
The shutoff diaphragm lists for $86.00
Is my shot in the dark correct?
Even though I am a Nissan Master tech, I also specialize in Mercedes-Benz and specifically Diesels, so if you need help, I'm here. I went through a few Mercedes Schools and have been swinging Iron in Mercedes since the 70's
I might be a little more informative than the public library.

Hello I'm a M.B. tech. As long as it is original there is no amplifier other than the head unit itself. The only tricky part is getting the antenna to work with the new head unit. Take a test light and find which wire is hot all the time. That will be your circuit 30 wire(radio memmory). Next turn key to position 2 and find your wire( one is for the antenna and the other is for your radio operation) and isolate those 2 wires,. Find your ground wire and those are your basic connections. There is a fader switch in your center console wood. the head unit sends its power ther and it is dispursed to the appropiate speakers(it is also a common problrm when you have no sound. Try to pop the switch up carefully with a flat blade screwdriver. If not pop up the shifter trim ring and pull up on the console wood. You may have to remove the ashtray. It is a fairly simple install hopefully my advice has been helpful.

It is not complicated, depending on what hands-on level of DIY on car. Here are what need to do, so you can estimate how easy or hard when you look through your engine. Drain all the coolant, remove the thermostat housing, remove the fan, belt. Remove the water pump pulley. There are 4 bolts to hold the water pump in place.If you think you can take them out and put them in without removing the AC compressor then you can do it. I did it twice without removing the AC. The pump was fine for the second time, but for leaking seal. At dealer, it is easier to access from the bottom since they have a lifter. But it is doable at home. Have fun if you decide to do it.
