I been having this issued for a while even toke it to a mechanic to run test couldnt figure it out got tired of carrying my code reader to erase the codes couldnt really understand much now i know that e320 does has 2 sensors, i knew i had seen them before but didnt really knew that was my solving problem all along thank u 👍🏼
Great video. I like your creative custom cut plug end as well as your custom car jack, lol. Your car has 4 oxygen sensors. The 2 other ones are connected at the headers before the catalytic converters one on each side. The other sensors are referred to as upstream sensors. If the downstream sensors are bad then the upstream would also be bad if they are the same age. The upstream sensors take the most abuse with the highest exhaust temps and are the most common to fail. You can borrow the sensor removal tool from your local auto parts store. They all loan tools. Its a special deep 22mm socket with a wide side opening on it to allow to go over the wire and hug the sensor nut. Good luck and great video!!
@@bobbybando7841 Correct. He replaced the downstream (after the kat). The upstream sensors can be found in the engine bay right at the header, before the first set of kats. My E320 has a V6, so there is a sensor on each side of the engine bay.
@@deanc24 hi Dean. I have a 2009 E320 Bluetec. I’ve ordered one upstream air fuel circuit sensor due to fault code P2A00. Sounds like you’ve had experience in changing it. I have asked a mechanic where it’s located and was told in front of the engine near the firewall. He emailed me a diagram that looks Greek to him, and myself. You mentions to cat converters? I believe it goes in front of one on passenger side, but is that in front of engine? I’m so confused. My husband is going to install it, but I have to find where it goes. Hope you can help. Thanks, Jan
@@janholcombe4538 the sensors measure oxygen levels in the exhaust. The upstream sensors are in the area close to where the exhaust headers merge into the exhaust pipe, but prior to the catalytic converter. Probably visible from the engine bay. Hope that helps
These $19.99 eBay O2 sensors are made in China and have spotty Quality Control. The old saying "You get what you pay for" applies. Don't put cheap motor oil or O2 sensors in your car - you will regret it.

Correction has 4 sensors 2 on bank 1 and 2 in bank 2

jo S are all 4 sensors the same part?
So to be clear the ones he replaced in this video are the 2 downstream sensors not the upstream?

You did a very good job of explaining the process. Now I'm going to try it on a 04 MB E500 4matic
Dremel to the rescue! Thanks for the tip
Thank you so much man I didn't even know that E320 had to CO detectors period man you are the bomb thanks again
Excellent video !
I will be attempting this 1st thing in the morning.
Was that the problem?? Did
your light stay off?
So how are they holding up?
He did this so class my guy used a fork lift lol not bad lol but now I know how to change this sensor
Great job mate
Did it run rough
Graat video!!!
would it be same on S320cdi. and is it oxygen o2, sensor 1 bank 1?
M MT did you get this sorted? My e250 is showing p0426 catalyst temp sensor bank 1
Dean Fletcher i believe the codes are same. Must be same sensor. Just need to crack on. Thanks

Absolutely 👌
Nice job ;-)
Half the time I couldn't even see what this guy was doing
Donot look ssfe
