Great video as always! should have WD40ed those bolts overnight though, may have come out, esp if they are open ended and you can spray them from underneath as well
I just replaced the pump the old one didnt work when power was applied this does but still wont come on i feel its not getting power or the solenoid is bad. I checked the relay and its good. What do u suggest
@@adrianechavarria-b1y any update... I just replaced my air pump lots of corrosion on wire connectors, I'll double check wiring for continuity tmrw getting ready for work .
ea i replaced the pump again it burned out but this time i changed the relay also its working but i got the code again for the pump i cleaned out the check valves and erased the codes i guess we’ll see. I turned it on this morning pump came on then shut down like its supposed to 45 sec later
Hi. Thanks for your videos. I have a similar car. 2002 M112 S320. Your help is really appreciated. When you say it smelled on startup, what did it smell of? The problem I’m having is that the air pump is on constantly. Even with a hot engine. Even ignition off and car locked. I’m going to replace the relay first. For the moment I’ve unplugged the pump to stop it burning out. Do you think I can drive with the pump disconnected?
Yes, the car will run, but forget passing an emissions test. The exhaust will most likely smell a lot stronger than usual due to the cats not fully doing the job when cold. This pump just pushes fresh o2 into the cats to get them working quicker. Thank your local green environmental bunny hugger for this extra crap bolted to your car.
Hi , l've sprayed wd40 in my air intake tube right behind the airflow sensor mercedess cdi 1999 , does it clean or harm the engine affer all , ps l'm having problems with high levels of smoke , thanks in advance!
@@doit_vehicles one time I given to car wash they blown all 6 coils🤦♂️. But I want to see my engine clean but scared to clean. Now days I clear myself.but still oil is there. I buyed form engine degreezer and clean with brush. It work fine still I am scared of that 6 coils.. tats why I didn’t pleasure wash the engine
When I wash. I remove the filter box and close that air intake valve with plastic. Then I spray the degrezer. And I buy one hand pump pressure washer to clean it.still sacred about the coils. Each coil cost 100aed
DON'T DO IT! If you have to clean it, get a jar of mineral spirits or varsol and a stiff brush. Dip and scrub, use a rag and a lot of patience. You'd have to be a fool to hose one of these nightmares down with water. You'll end up chasing codes for the next decade!
I have 2005 ml350 w163. The pump comes back on and off 3 to 4 times when the engine temperature is around 79°c to 80°c . Any advice or ideas please 🙏 Thank you.
I did not think it could be the relay, because the fan works the way it should at cold start for a minute or less. Than it comes back on and off 3 to 4 times when temperature is around 79°c to 80°c then off until the next cold start.
@@adebayooni1673 In my case it wasn't the pump making the noise. Turn out to be my radiator fan making the loud noise when it kicks into high gear. I changed the fan and the high pitch noise is gone
Very refreshing to see actual diagnosing instead of just replacing parts!
Very impressive. He is not just a good mechanic but his hands on engineering training speaks in practice. Thanks for good explanation.
Very good explanation and I like the style how you show.
Thanks for video👍

Great video brother, keep up the good work
Thank you! Great lesson!

Chuck the Wireless, connection , corrosion etc
@@doit_vehicles i just also bought the solenoid. When i put it on il check the wiring. Thanks man

The cel came back on anyway. U think its the check valves?
Thank you
But can you tell us where are the fuse and relay for it
Great job.
Please w210 cdi
Thank you for the video. What is the milage of the car? It would be good to know at what milage selonoid valves became bad.
it has 350 000 km
bonjour , mais a quoi sert cette pompe ? je ne l ai pas sur ma s320l w220 de 12/1999 , est ce normal ? y a bien le support mais pas la pompe ...
You top

@@jagboy69It was the relay. Replaced it for €20.

Hey everyone... Can a air leak along the seam in the secondary air pump cause a P0455 large air leak code ?
No,P0455 is leak in Evap system,the one capturing gasoline vapors.
Please tell me how to bypass the air injection pump? In my case pump is good but no power goes thru it
Remove the connector from the solenoid . You might get the check engine light on .

It kind of does both , but you will need a lot of spraying to clean the valves which also might damage the engine or catalytic converter
@@doit_vehicles thaks a lot for replying and for the advice, all the best to you !
Why not just spray water then ?
CAn you explain how to engine wash the w220 without any problm?
On this engine it requires to take each part and clean it aside like the main components: intake , valve covers . At least that's how I would do it

can you drive without secondary air pump?
Yes it is only meant to heat up the cat faster for emissions you can actually decode it, and just remove it if you want with the correct software

To be certain it's the pump, unplug it when you hear the noise
@@rodflo2979 I did that .

I mean the pump. Not the fan
I have a 2008 e550 and the pump comes on and off while I am driving or at a stop while the engine is running.. Any idea what's wrong?
