Hi Guys. Update on my previous comment. I succeeded to replace and connect loose or damaged vacuum lines, and the one I mentioned before goes to the firewall, but I don't know what is doing there. Anyway, the back headrests still do not work after this. Regarding the connector to the switchover valve, the reddish wire (red and green I think) is always negative, but the other one which is grey or white with an orange or brown line (not easy to define unless I cut the protection), don't have the positive during the first few minutes of a cold start, or so. I inspected all the relays and fuses in the boot and at the front and, in addition, two of them (K and R) were tested while plugged. Thanks, doit for your video on disassembling the intake manifold, which I partly followed to do the job. The greyish wire coming from the switchover valve seems to end up at the front fuse box; I tested one with a similar colour and it has 12V positive but it is for way too long after the engine starts. What makes me confused is that this same wire appears to have continuity with the one in the connector! I need to double-check that. I don't know yet how to connect the vacuum gauge. By the way, I have not yet tested the car on the motorway, but the idle is definitely more consistent. Regards.
Just a site note. You dont have to remove the supply line. You just unscrew the check valve. You can do it if you make a special key by cutting a head of a if i remember 27 wrench. Mercedes mechanics of cors have access to original removal tool. The real problem is in the valve. Cleaning wont help. Its a design flaw. Over time the rubber seals wear out and the exhaust fumes will over time destroy your second purge valve. Tipically the last 60 - 80k miles. I think I have a masters degree for secondary air injection troubleshooting, as how long it took to find the problem :D
Great video and very good instructions! You helped me to repair my 2002 CLK C200. Thank You very much! My best wishes for You from Finland. Keep going :)
Hi, I know you must be busy so maybe someone else can help me with this question and do a small test for me. When I unplug the harness from the switchover valve and test the two wires I'm getting 4 volts on one wire and 11 volts on the other wire, does anyone know if the voltage is correct or should I be getting 12 volts and ground?
Hi, doit. I always like to come back to your videos. I still have this car. After one year I have not discovered why the switchover valve connector doesn't have 12 volts when the car starts cold. Besides the three vacuum lines that go in/out of the switchover valve, there is a fourth vacuum line hanging loose underneath the top assembly, which is connected near the vacuum line plastic tube coming from the switchover valve. I don't know where the other end should go. Any help to solve these issues is welcome. Related to this matter is how to connect a vacuum gauge in this car to do a diagnostic check. Take care doit and guys, your contributions are very helpful.
Great video . i got p2031 and p2036 on 2001 Mercedes c200 w203 i clear the code i tested the o2 sensor upstream by add fuel source to the vacuum line read rich when i apply vacuum it read lean . what do you think the problem thanks
Bonjour j'ai une c230 2002 condition très bien jamais sortie l'hiver je trouve quel coûte très chair en essence que faire Merci ! pour vos vidéo je viens dans prendre connaissance
big fan frpm day one!!! Can you do a troubleshoot video of the fuel gauge ? my car goes out of fuel 5 km after the reserve light has com on. Thanks in advance.... I know it might take some time. Cheers and very informative video as usual !!!
Hei ! thanks for beeing around . It sounds like there is a issue with the fuel level indicator ; until I do a video about that , you might wanna check the fuel pump assembly and test the fuel level potentiometer . Is the same as a throttle body or acceleration pedal or any other sensor Here is how to remove the fuel pump with the fuel level sensor : ruclips.net/video/WyMbpITvlRA/видео.html Cheers !
Did this today, to clean the check valve you do not need to remove the torx holding the pipe line or check valve, just raise the car, and remove the big 27 bolt holding the fitting, you will have enough space from underneath, remove the perforated bolt, careful not to loose the two crush washers, one behind the head side and one on the other side of pipe. take a peace of 5 by 5 inch aluminum foil and slide it between the pipe and the intake manifold side, to block anything you will spray through the check valve. I used a pulverizer gun and gasoline to clean the check valve which was almost completely clogged. all the junk came out of the pipe, the aluminum foil sheets blocks all this junk from entering the exhaust system. Done! no more insufficient secondary air flow code.
Would you have any idea why my change over valve has both wires are positive? I have a 03 c230 and 2011 c300 they both are showing positive on both wires
Brother do you know about cold engine vibration? I have a Mercedes w203 c220 cdi. When the engine is cold, there is a strong vibration and Rpm is moving a little up and down in idle but after 30 minutes when it's warm ,the vibration is not any more. I have replaced both engine mounts , spark plugs, and a used egr installed. The car also smells badly when is start . Can you please help me?
Blessing I have a 2005 ml350 W163 code P0412 secondary injection pump valve A malfunction, the pump runs every time the engine is cold all fuses are good my problem is I'm not getting 12volts at the solenoid when I crank the engine. Your answer is highly appreciated.
Try to inspect the wires for the selenoid to the PCM ; Is it sure that the selenoid is not activated by during a cold start ? in the video about the Oxygen sensor I do that . Basically you cehck if there is any short or damaged wires betwen the selenoid connector and the computer . Thats the only thing I can think of with these symptoms you told me .
Hello Doit_Vehicles. Am kindly asking for your advice, I have a C200 2001 cl203 coupe with M111 engine and C180 2001 s203 estate wagon with M111 engine. I want to swap the engine together gear box.

I have C240 2007 w203 112 engine, I have problem when the engine is running, the car shaking, I tried to unplug all coil, seems like 3 coils are broken, i have changed with new coil. but the problem is still the same. The engine on low RPM shakes the car a lot, after I try to speed in a free way, the RPM can go high as I kick down the throttle, but the speed and the power of the car wont go up. any idea why this is happening?

Hello great video, it explained much more clearly what I needed to check, to get rid of my PO410 code.
