2007 C230 Sport/ I've had the car for 15 years now/ I usually hear this pump for the first 10-20 seconds during a cold start / yesterday morning the sound stuck around for what seemed a minute or two. After I drove off and was sitting at a traffic light the car felt like it wanted to flame out. Not sure if the two are related. I checked the hoses to make sure none were lose or disconnected and the car has not repeated the same minute long whine/ idles at about 300 RPM with no noticeable sign that the engine wants to flame out. I suspect the long whine may be this one component/ close flame out may be something entirely separate (new coil packs and plugs went in last year). Hoping to keep the car running another 3-5 years if possible so I hope its not anything major. Thanks for the content.

I had the same problem with my certified pre-owned 2010 E350. It was under the Mercedes CPO warranty, so the repair was covered. The issue that I ran into was that the secondary air pump failed every single year, so I had to replace them yearly for 3 years. The last time it failed, the warranty had just expired, but because it was replaced just under a year ago, it was still covered under the factory part warranty. This time the dealer looked into why the part failed every single year and they found that the secondary air shut off valves were leaking exhaust when closed. They ended up replacing both left and right bank secondary air injection shut off valves and that solved the problem with the air pump prematurely failing. Because my CPO warranty had already expired, the dealer got Mercedes to agree to cover the parts, but I had to pay for the labor.

@@carquestions That was what was listed on the repair order on what they replaced. I believe that was what fixed the problem, since it has been three years since that repair and the secondary air pump has not failed since. What ticks me off is they never bothered to look for what was causing the secondary air pump to fail prematurely when I had to replace it annually, not until my CPO warranty had expired.

Thanks for this video, my secondary air pump is making a similar noise, the pump looks like a glorified two stage shop vac blower. The black dust you blew off was obviously wear material from the brushes so I'm not sure if it was addition of grease to the bearings or the removal of the excess dust that actually got rid of the sound. I will be removing and disassembling my pump and will also try to see if I can't replace the brushes as part of the cleanup and lube process.

When a part costs $700 and you can find it on eBay for under $100 I'd be a bit suspicious of quality however the pump is little more than a DC version of a two stage shop vac blower and you can buy an entire shop vac for under $100 so who knows. My policy on eBay is always "buyer beware" but there are good products on there at greatly reduced prices from OEM. The disassembly process didn't look that time consuming or complicated and even at $100 the two hours it probably took to disassemble and reassemble it would equate to $50 per hour, I used to make that kind of money and even then I favored DIY wherever possible and put the money in the bank, I guess that's why I retired at 53 with all my toys and it's play time. The only step I'm going to try to add to this process is attempting to locate and replace the brushes because the black dust he blew out of the unit was brush material so I'm not sure how long his customer's pump will remain quiet if the brushes are worn below spec., in any event awesome video.

Sounds like your guys arnt really replacing the pump with a new one. Clean and shine up the old unit and back in it goes! Theres not much to wonder about the seconday air injection pump. Just a electric motor that runs off 12 volts. Super easy to test with just 2 wires to a battery. If it fires up then your pump is good with no reason to burn up. Unless: but it does run off a relay in the fuse box. When you start your car the air pump should stay on for only about 20-30 seconds then shut off. The relays are known to go bad now and then and thats where the air pump stays on and wont shut off and the air pumps burn out and fry. Thats possibly what your smelling. Id bet your guys didnt replace the relay which is only about $15 bux. Relay is 10 second job like a fuse....just pop the old out and plug in the new one. Hard time believing your guys have put in 3 pumps that run on a 12 volt system and they all burn out. 🙄 😒 😬

A check engine light brought me here. I checked with a code reader and got P0410 secondary air injection system. Followed by another code 0814-00 Malfunction of secondary air injection at left bank of cylinders (function chain) (P0410). I visually inspected all connections and hoses and those seem to be OK. Mine does not make the noise the one in the video did. Any suggestions?
@carquestions6 жыл бұрын
Change the pump - here's why - I changed one out a noisy one and a week later the code came back but the second SAP wasn't making noises like the original one - put in the third one and it has been fine ever since
@rodflood28782 жыл бұрын
Excellent video technique. Our 2011 C250 was making a noise for a few seconds upon cold start which sounded like a bearing in a pulley (kind of like a squeal - instead of a jet). After a week the noise stopped but got check engine light and P0410 "secondary air injection system". Engine runs fine. Would you hazard to guess it is this air pump ? (Go Canada go)
@carquestions2 жыл бұрын
Rod - When I said jet engine I mean - it's a very high pitched screech / squeal - so I think you definitely need an air pump replaced.

You look like your super honest! I wish i was in canada! Do you think that after getting the transmission selenoid codes i need to change the whole valve body? They’re trying to charge me 1,150$ for that on a 2010 e350. Sometimes i turn on the car and it operates food the whole day! Other times it goes on limp mode! Is my transmission bad? Should i just junk it? I like the car but im afraid its not worth the money if the transmission is bad

@@carquestions thanks. Great vid btw. I’ve noticed my air pump stays running at all times is this another symptom of failure? Also could it be related to the random misfire like feeling I’m getting from the engine? I don’t have any codes but I do notice occasional stutters that feel like misfire and when I watch the engine with the cover off it seems like it is hesitating quickly at times. Creates a minor vibration in cabin.
