How do I remove and replace head light wire harness in my 2001 mercedes e320

the e320 has been known to have elect harness problems the insulation that was used deteriorated and wires were shorting out and or melting the whole harness ---the other is your bcm [body control module ] is damaged or gone bad but look into the harness first

is the 'battery' light on, then it needs to replace the alternator, only need to remove the belt and 2 bolts, and then wires at the back of it.

You have to carefully remove the inner door trim, disconnect the airbags and then remove the weather stripping. There are some obvious nuts/bolts & clips that you will see.

It pretty straight forward of you open the hood and look at the back of the headlamp. You see a metal clip right where the wiring harness plugs into the back of the lamp. Just take a common screw driver and pop the clip out (be careful you don't pop the clip down into oblivion as it does tend to spring out with a bit of force.) The clip is held in place by two star headed screws. You do not need to mess with these, just pop the clip out from under the screw head. I assume it will say something to this effect when you buy the new bulb but be sure not to touch it directly with your skin as the oils in your skin will shorten the bulb's life considerably.

your control switch is faulty on the steering column

Hi Rafal Joe here to help, There are two torx head screws on the back of the steering wheel. It takes a special Mercedes Benz tool to do so. After removal there are airbag connectors that need to be removed. Be careful not to break them, They are plastic.

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!

have yor dealer check for updated software for your transmission or engine control modules

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.
