Mercedes P0410: 5 Crucial Tests to do for Secondary Air Pump.
This is the issue on my W164 M272 engine but almost any Mercedes from 1997 to 2020 has a secondary air pump that has similar components.

Hi all, please test all the 5 components before taking your car to a shop or buying parts and save money on P0410 Secondary Air Pump...cheers Max.

You covered very well. If all parts test fine and P0410 still shows up, then it may be exhaust manifold air injection passage clogged by carbon which is the worst worst scenario !

So what fuse was missing for the camshaft or the secondary air pump?

My pump burned out. I changed my pump, fuse, relay, solenoid and I checked the 2 vaccums they were clean. What could be wrong??. I did have an eval leak I fixed it by changing evap purge valve. But my p0410 code never goes away.

@armendshaqiri7621 Clear the code, check to see if the valves open and close as they should.

Hello, I have a fault code 0694 M4/7 is not working correctly. The engine fan fails sporadically but comes on when you activate A/C. Do you recommend changing the motor fan or maybe it can be fixed? Regardss!

Needs diagnostic tools, take this seriously as you might end up with a blown engine.

@@BenzAddiction mmm, better to change it, new or second hand one? High temperatures are coming in 2 months. Spain Summer.

What working temperature is appropriate for the engine?

The cable that is connected to the secondary air pump does not have power. Don't you know why?

@BenzAddiction Ай бұрын

It only powers up for a min after start up usually. There is a relay that can go bad as well as fuse.

@@BenzAddiction I'm just changing one of the valves and checking the lines I have the code p0410 and when I turn on the truck it smokes but the secondary pump doesn't work, I removed it and tested it and it works. Now one of the valves was not working and I had it installed tomorrow but I wanted to see if the secondary air pump cable had power but I never turned it on to check if it had power. Because of this code, is it normal for smoke to appear?

@BenzAddiction Ай бұрын

If you do the tests one by one it ticks off all of the components and hopefully you'll find the issue, smoke should not be related to air pump. This pump only injects air to exhaust. With valves stuck open you might get some exhaust gas in to the pump that can ruin it and produce extra noise.
