I have a 2000 E55 AMG VIN: WDBJF74J4YB133714

I'm looking to replace the two O2 sensors upstream and I'm getting conflicting information on which ones to get and wanted to know if anyone knows for certain which are the right ones. I'm looking to get bosch sensors with OEM connectors. Various parts stores such as autohausaz and pelican parts state I need the following:

Bosch 13642 - Left Front
Bosch 13798 - Right Front

However going to the Bosch website in putting in the vehicle information yields different results:

Bosch 16274 - Left Front
Bosch 16353 - Right Front

Any help would be appreciated.

That's HS---the correct part is 000 540 81 17 for both sides. FYI the 02 sensors are after the cat's

There are a total of 4 O2 sensors on this vehicle. There are two sensors before the catalytic converters, one for each bank. There are two sensors after the catalytic converters, one for each bank. The part number you listed is for the sensors after the catalytic converter.

First of all the sensors before the cats are not O2 sensors they are lambda control sensors and the sensors after the cats are 02 sensors---do you have any idea what you want,because you asked for 02 sensors---------and they are all subject to a VIN----so be careful what you ask for or go to a dealer for the correct information!

Yes they can be called lambda control sensors, but pretty much every parts vendor and person calls them O2 sensors. So you're in the minority there. I placed my VIN in my original post for helpful people to help me, and you're not being helpful.

Please go troll in someone else's post. How much does the MB dealership association lobby pay you to troll this board anyway?
