2003-06 Mercedes E320 (W211)// P0410- Secondary Air Injection Troubleshoot/ THE FIX!!!!!

On this video we will be chasing the problematic P0410 code!! This repair can easily become an expensive repair in a snap of a finger!! Tag along and see what solved the issue for this W211 E320 benz! Also, I forgot to mention do not start with the injection pump first! In my case the pump had to be replaced because I had tested it and there was no power or noise coming from the pump. First test your pump before replacing it. This E320 had multiple issues, so this one was tricky! This W211 was one of the hardest, vehicles to trigger all 9 monitors to pass emissions!

a lot of good information . i thank the mechanic and the car owner.

[@Fwerks.1592]

Thank you!! I thought I’d share the information I came across. It can be many things.

[@warithsalum1049]

Appreciate for the video… i have an 03 sl 350… has the same engine and its bringing up the same code… i will try doing what you did step by step and keep you updated if anything pops up

[@haramaschabrasir8662]

I did the valve cover gaskets and oil breather gaskets myself without any car repairing experience. Pretty straightforward, BUT you still have to be careful. Don't skip steps. If you're not sure that the gasket is sitting correctly, better check twice.

[@johnkolowitz]

Man great video dealing with this code now and it's giving me driving issues but I know where to start now myself

[@Fwerks.1592]

Thank you brother! Not too many videos out here for a P0410 and if there is everyone is doing the secondary pump! I just wanted to share my experience and hopefully I can put more videos on this E320!

[@jayi836]

Another stubborn Mercedes my SLK is the same thing Thanks for sharing

[@josecruze9578]

Thank you for your video detail. This makes a lot of sense with replacing the valves and cleaning the inside of the manifold housing where the valves sit.. I replaced them and did not clean the inside where they sit. I have a 230c 2007, and I have replaced everything else but did not clean the inside where the air valves sit. Hope this will be the last thing [ need to do to get this code to turn off. So I can take it to get smog test done.

[@Fwerks.1592]

I really think getting that carbon build up, would really help!

I’m having the same problem with my 07 E350 and I replaced a bad air pump and took apart all the hoses and everything is free and clear and was good for a month and now I’m get the P-0410 code every morning I start it.

[@Fwerks.1592]

Have you check your check valves? Also know as the kombi valve?

hi i just want to ask. i change the relay, fuse and the secondary air injection pump but my pump still dont work. do you have any idea why? thanks

[@Fwerks.1592]

Thanks for the support! Hopefully I can get more content out on this chassis soon!

[@eyalbarmitzvah]

At 13:19 when you smack the valve and yank it off that breaks it. You really should warm the engine first to let the metal reduce in size, then gently twist at the base and turn back and forth from the base and never from the top.

[@Fwerks.1592]

Thanks, I’ve seen and read about all these valves breaking. Never have I seen one come out clean without breaking. I’d also prefer to work on a cold engine bay then a warm/ hot bay. Trying to avoid burning the hands 😉

Well shop didn’t do anything but got 2 new battery’s & a crank sensor car starts right up & last night I open the secondary air injection & got the fan to spin I open it up & got carbon all out so it works now . Wen I plugged to car don’t turn over so I’m sure is relay . But nex step takin the check valves off to see if there clogged would it cause my car too jerk ??

[@Sinister_187]

& gettin a new line for the check valves

[@nikywest5988]

I was told my code was for Secondary Air Injection at left bank of cylinders (function chain) also at right bank of cylinders. I replaced the pump but it was still showing so I took it to someone I trusted. They won’t work on it so it’s currently not running. I have a C 300 4matic

[@Fwerks.1592]

Why wouldn’t he work on it if I may ask? I’ve worked on a c300 for this same code. Let me dig up the info on what I replaced.

[@nikywest5988]

@Fwerks.1592 I live in a very small town in Iowa. Every shop in town has told me the same thing. They can diagnose it but they won’t touch it. I live 2 hours away from any bigger city. That’s where I would have to take it to get it fixed. I can’t even drive mine right now because it’s completely clogged up. I can’t just have anyone work on it either because of the warranty but the warranty company don’t have any shops in Iowa or towing companies. I would have to pay all out of pocket to towed to wherever they have a shop and yada yada.

[@clk5005]

I got the same code. Also noticed there is no vacuum on any of the lines connected to secondary air pump an the small ones that go to the egr an the electric valve sensor

[@Fwerks.1592]

Those Egr valves may definitely be clogged!

[@J8den]

What do u think mine is? P0410. Replaced air pump and Relay (and fuse) because I got the code and the fuse for airpump was out but then it came back after 3 months so I went straight to the 2 Check Valves but both were clean!!! . Still cleaned them again just incase and it came back Do you think its the 2:16 Electric “Change Over Valve?” Aka “Injection Control Valve” ? idk i already bought it along with the blue thing because it was only like $22USD and its on its way, I am going crazy and broke buying parts lol I will keep you updated but I want to hear your thoughts

[@Fwerks.1592]

Interesting! Keep me posted if that injection control valves solves the issue. Do you have access to a scanner? Any codes pulled up? In my experience with another Mercedes, check that fuse again that goes to the pump! I had this c300 with the same code replaced the bad air pump along with a new fuse and everything was fine. Two days later the code came back! After testing, I sent the pump back to FCP euro and got a new one. The new pump was working and the code went away with a reset. Can you hear your pump go off when you start the vehicle?

[@prosibious-4435]

How much did you charge to get it all fixed? I have a 04 e320 and my OBD scanner and I got that code.

[@Fwerks.1592]

The repairs can easily get expensive! If you take it to a Indy shop expect pay for a secondary air pump with labor around $400-$480 if they replace the kombi / injection control valves, that’s roughly $450-$500 with also cleaning the carbon . This is just a rough estimate!

[@itzzchurro4505]

what parts are those called that u take off at 12:42 and where can I get new ones for a 2003 e500 5.0

[@Fwerks.1592]

Those are called the Air Pump check valves, also known as the kombi valves.

[@rigom.5438]

hello ! just checking out your channel cause my C230 2003 is getting the exact same code. when i take it to look for the piece at auto shops they say my car doesn’t HAVE that piece. Any advice ? 🥲 i’ve already changed the Air injection valve and the secondary injection valve. IM LOSsSSSSST

[@stillridin9600]

I need this in my c class 240 can't pass emissions same code

[@Fwerks.1592]

This video can point you to the right direction! P0410 can easily get expensive if you just keep throwing parts at it. Check all your vacuum hoses first. Inspect for any cracks, tear and make sure they are connected. Next check if your secondary air injection relay is good, and then check air pump! Next move on to the kombi valves which you’ll be surprised they will be filled with carbon.

[@inkdown]

Did you have any symptoms aside from the DTC?

[@Fwerks.1592]

There was actually no symptoms besides just the check engine light.

[@vv6292]

How did you get the broken piece out?

[@Fwerks.1592]

I used a flat head screwdriver and chiseled around. The metal from the broken piece is very soft! Take your time and make sure you don’t damage the port to the manifold. Also try plugging the port with a blue shop towel so you don’t get any pieces inside the port. Then use a vacuum to clean any debris from the port.

[@vv6292]

@@Fwerks.1592 Thanks. It was indeed week. I started with a screw driver, but like you said a chiseled work best and faster. And stuffing the port hole with a blue shop towel worked as well.

[@Fwerks.1592]

@@vv6292 were you able to get all the pieces out??

[@101skinnydipper]

Dam so it wasn’t the actual air pump it was those air valves ?

[@Fwerks.1592]

Indeed! This was probably the hardest P0410 code to diagnose! Since the pump was initially bad, so that threw things off and turned out the ports were heavily clogged with carbon!

I need a new hose next to the check valve hose what is it called? The one your holding 1:35

Do you have access to a multi meter ? Turn it to ohms and check the reading. If it reads 10hms~14oms it should be fine. Anything leas than that or readings that are all over that place, should be faulty in some cases.

Great video! I've been dealing with the same code for a couple months on my 1998 e320. My main issue is removing the broken stem that gets seized in the check valve port. Can you explain how you removed yours? I wasn't sure if I knocked it down into the port would I be able to pull/suck it out. My fear is that it would get permanently lodged in the intake. Here's the part of the video where you discuss this issue... kzbin.info/www/bejne/gnLOdICIodOtqLs

[@Fwerks.1592]

Sure no problem! I actually used a flat head screw driver and worked it by tapping it with a hammer. Try to cut it from on side. Once you break the ring, you can slowly start prying the metal around. Don’t worry the metal is super soft so it will bend quick! Also if you want use a blue shop towels those are thicker and use a little bit to plug the intake hole just enough so when the stem pieces fall they fall on the paper towel. Once you finish you and vacuum any pieces and also use a pick to remove the blue paper towel. The hole on the port is pretty deep it’s about a good 4-5 inches till it reaches the intake. Any other questions feel free to email, I can walk you through the steps. [e-mail]

[@focusmd]

@@Fwerks.1592 Thanks for the detailed fast response. I tried something similar before but didn't force it for fear that the pieces would be forever lost in the intake. Mine seems to be welded in the port. It would help if I knew the inside of the path of the port to the intake. I will give it a try and let you know if I have any further questions.

[@focusmd]

update: I was able to get the passenger side check valve off w/o breaking the tip. It was full of carbon in the part and in the intake port. I thoroughly cleaned it with brake clean and the p0410 has not come back in 3 days. The car passed inspection so I'm good to go for now. Again, thanks for the help. Now if I can get rid of my rough idle I will be happy...lol
