Before checking the relay or fuse, please check carefully the hoses. From your video, starting from 0:56, the white hose connecting the EGR valve next to the secondary air pump is broken. This could be a potential cause of the code.
I have this code and I believe my issue may be tied to one of the hoses or the surrounding check valves. Is there a way to inspect those before changing them? I can hear my 2ndary air pump when i start the car and also there is a bit of a whistling metallic sort of noise...
This is only part of the diagnosis, the fault code description for P0410 is secondary air injection system low flow, which could be the fuse, wiring, the relay, the pump, one of the two diverter valves or (most commonly with higher mileage motors)clogged passages. There are chemicals and additives one can buy to clean the passages in the head without having to take the manifold or head off of the motor, along with a speedo cable on a drill to dislodge any carbon build up. When using these methods, make sure the exhaust valve is closed as to not allow any carbon into the combustion chamber, as well as with the chemicals, not to allow it to fill the cylinder up and cause the motor to "hydro-lock" and possibly bend a connecting rod.
Can you help me? When my car's engine (M112/3.2) is hot, this pump turns on for 5 second and then off, then again and again. What can be wrong with it?
Ur right i have checked everything to see was the problem on that P0410 code. Finally found the problem they where the air pumps air valves where clogged up with carbon. Either u can clean them or buy new ones. Once u take them out u can see all the carbon build up inside the manifold also.
I need your help I just put a new fuse in for my secondary air pump it turned on the secondary air pump but the fuse ended up breaking and I don't know where the problem is or where else is coming from
Hi thx for this . Please I need help I have mb c350 1 2006. W203. Same air pump here. What does this pump? Pull or push air ? My pump PULL air in the hose arrow to admission. Is wrong ?
hi thank you for your videos and knowledge I have code p0410 on my mercedes e350 2010 w212 fuse keeps burn as soon as start the car how I can make sure that pump is gone and what's is your opinion I hope that you can reply ASAP because I am not driving the car thank you very much for your effort
Hello friends. I have Mercedes W203,C 180 (129 Xp) 2001 with the fault code description for P0410 . I have been inactive secondary air pump. Have you any idea where is secondary air pump relay location? and the fuse too
I am trouble shooting this right now. That relay is not for the pump. It is the starter relay for the engine. I jumped the contacts to get the pump to turn on and the engine started to spin. The fuse is correct one. I think the pump relay is inside the black box, where the fuse is plugged into, known as K40 relay module. Relay is not accessible unless you open the module.
Hey, so my code has been coming up forever. I bought new air pump, new relay fuse, and still coming up. Should I get a new air injector valve ? Or new air pump control valve?⁉️please and thanks !
Hey guys I have a 2003 Mercedes c230k with a PO410 code.I bought a relay but my car does not have a diagram showing which relay is the secondary air system.Can you help?
I have w211 2004 E500 more than one year the pump not working and I already replace it but no power coming to the pump I tried to find the fuse and relay but not mentioned any where, any one can help?
Hello Guys. Can you help me? When my car's engine (M112/3.2) is hot, this pump turns on for 5 second and then off, then again and again. What can be wrong with it?
Hey bro can you please please PLEASE help me out!? I'm getting three codes. P0410 P0174 P0400. Starting with the first. I have a 2002 Mercedes-Benz C320 Base 3.2L. I'm getting p0410 cel code. I've tested the secondary air pump directly and it works perfectly. But when I go to check the voltage at the 40amp fuse, nothing. There is no power at all when the car is off or on, cold or hot. I pulled the relay and checked it and it is functioning perfect on all terminals with 0.001 resistance. Am I missing something here? Why would there be zero power at the fuse? Shouldn't the fuse have a constant 12v and be wired in BEFORE the relay? I'm just about ready to pull out the entire fuse panel and rewire the secondary air pump. Has anyone had this problem before? Tomorrow I will pull the egr valve and tube for cleaning. Hopefully this gets me somewhere on the P0400 and P0174 codes. Does anyone have a diagram of all vacuum lines on this vehicle? I've traced and replaced a few lines, but I am very sure I have a vacuum leak somewhere that I don't see. I do not have access to a smoke machine. But would the cigar technique work? If so, where should I be pushing smoke in? Any help is greatly appreciated! I'm not sure what other relevant information I should include. But whatever I am lacking, please let me know and I will immediately go out to my vehicle to get it.
Power is only intermittent at the pump, the first 60-90 seconds at (cold) start up and after a drive cycle for OBDII readiness monitors. Check the passages under the valves (one E10 bolt mounting it to the manifold) and make sure they are clear, you can even start the motor to see if you get a steady stream of exhaust from the openings where the diverter valves were mounted.
Kind Sir, may I ask a question? How do I check the relay on my 04 e320 Mercedes wagon to know if it is bad before I check the pump? Please and Thank You in advance. Hello?

You are the master ,I have the question for you ,I have Mercedes Benz s430 2004 y al plug the air pump no has power and the fuse no power what happens
Before checking the relay or fuse, please check carefully the hoses. From your video, starting from 0:56, the white hose connecting the EGR valve next to the secondary air pump is broken. This could be a potential cause of the code.
that was probably the issue good catch
Yes I own a 2000 Mercedes’ Benz clk430 and the hose are cracked
I have this code and I believe my issue may be tied to one of the hoses or the surrounding check valves. Is there a way to inspect those before changing them? I can hear my 2ndary air pump when i start the car and also there is a bit of a whistling metallic sort of noise...
I have the exact same hose, and it has a small hole in it. I’m going to try and replace and and tell you if that solves my code
Very informative and very visually pleasing. 😍
All of your videos are AWESOME!!

Brian Peterson: Thanks for the extra info, on top of the video.

Brian Peterson is this an expensive repair at the dealer
Have you any idea where is secondary air pump relay location and the fuse ?Thank you in advance

Are you certain the black relay that you removed is for the secondary air pump? I thought it was the starter relay.
I need your help I just put a new fuse in for my secondary air pump it turned on the secondary air pump but the fuse ended up breaking and I don't know where the problem is or where else is coming from
you have a vacuum line broken...
this is awesome i have a c220 and i have a p0401 but im glad its goign to be able to be fixed so easily
Hi thx for this . Please I need help I have mb c350 1
2006. W203. Same air pump here. What does this pump? Pull or push air ? My pump PULL air in the hose arrow to admission. Is wrong ?
Can this pump be repaired or cleaned?
Awesome video. Thanks a lot.

Thank you for this video
Thanku so much
Not to mention the broken vacuum tube on your map sensor.
That alone will cause p0410 code
Hi guys i have an 02 clk430 po 121 code I replace the the sensor it worked good for a month then started hesitating again what can I do ?
I am trouble shooting this right now. That relay is not for the pump. It is the starter relay for the engine. I jumped the contacts to get the pump to turn on and the engine started to spin. The fuse is correct one. I think the pump relay is inside the black box, where the fuse is plugged into, known as K40 relay module. Relay is not accessible unless you open the module.
did you notice that clear vacume line was broken
How did you do? I replaced my pump and still the light came back on. 😔
@@RetroBoyVRrr did u replace the fuse too? 40amp fuse.
Try reseting the mil with a code reader too.
@@terrenceg3257 the fuse looked so I did not replace it. The relay tho which one is it?
@@RetroBoyVRrr use a ohm meter to check the orange 40 amp fuse. U cannot access the relay. It’s inside the module.
Hey, so my code has been coming up forever. I bought new air pump, new relay fuse, and still coming up. Should I get a new air injector valve ? Or new air pump control valve?⁉️please and thanks !
Hey guys I have a 2003 Mercedes c230k with a PO410 code.I bought a relay but my car does not have a diagram showing which relay is the secondary air system.Can you help?
I bought a new pump and still get P0410 and the pump turns on but be loud af, any idea or why it does this?
Thanks
What does the secondary air pump actually do? Will it hurt the performance of the engine if not fixed
redbaron2448 it smells terrible like burning gas
I have w211 2004 E500 more than one year the pump not working and I already replace it but no power coming to the pump I tried to find the fuse and relay but not mentioned any where, any one can help?
It could be that your vacuum line to the control valve is also broken... like in this video. Lol
Thanks bro!
Air pum part number or where to get ir, thanknyou!

Thank you for your video.

i need more w 208 videos
What accent is that?
You need to work on your heavy accent pronounce the words better can't understand you
Thank you for this video
