Oxygen Sensor Mystery

Hello gents.

Wondering if anyone can explain the following:

I drive a 2011 535i xDrive. The dealer indicate the part number for my Bank1 Sensor1- O2 sensor (P0133 OBD code) according to my VIN is: 11787596908 (520mm length).

I took my car to an independent shop and they said the supplied (520mm) sensor was too short!?! I picked up the O2 sensor that was removed from my car, then took it to BMW; the part number of the O2 sensor removed from MY car was 11787589476 (740mm length). The BMW department said that this part number doesn't match my VIN!?!?!? They indicated it's for a BMW X4?

Any thoughts why my 535i would require a longer O2 sensor than would correspond with my VIN? I'm the second owner, but I don't think any exhaust mods have been done.

Here's the three part numbers: (photos attached are the three pieces respectively)

1787596924 (740mm) or Bosch 17008
11787596908 (520mm) or Bosch 17015
11787589476 (740mm) - BMW X4

The longer 11787589476 was also used for the F11, European model.
Which engine versions do you get in Canada? The US or EURO?

I would just go back to the factory setup.

I guess that's the problem. I can't go back to original, the shop is saying the OEM part number is too short? Used your link. I'm the U.S. market apparently.

I'm concerned the reason is was getting the P0133 (bank1 sensor1 error) is because the wrong O2 sensor was installed?

Check out the VIN specific part number.

If I'm not mistaken, even the connectors look different.

Here is an engine with the short cables:



and here is a longer one (same engine but different car and turbos)

Yeah that's the wrong engine.

The F10 535i has the N55. I think the image you posted is the N54.

Yes, fixed it. But the arrangement is the same. The longer sensor cable doesn't go straight up to the top of the valve cover


In fact, I may not posted the wrong engine. I have fond many references to that. Engine is N55 but different turbos and exhaust.

Um.. not really, why are you saying it's the same engine when it's not. You have one N55 engine photo and a N54 engine. But we can't see any of the O2 sensors on the N55?

Why are you saying you MAY NOT have posted the wrong engine? You clearly have a N54 and a N55 engine. The layout is very different. Pre-cat O2 sensors on the N54 come right off the exhaust header, on the N54 they are pretty much right on the Cat.

In my first picture you can see the Pre-cat bank1sensor1 because it has the silver heat shield and is poking out of the cat. In image 2, there's a N55 cat with the pre and post Cat O2 sensors. In image 3, you can see the bank1sensor pre-cat O2 sensor sticking out of the front of the cat.

THIS is a N54 exhaust manifold. See how the o2 sensors are plugged in right there! Very different than the N55.. not sure why you keep trying to say they're the same with different turbos. It's the different turbos/valvtronic/etc which makes a N55 different than a N54.

Funny that you got so angry about it.
Why would that matter if I'm wrong?
Multiple websites referred to these pictures as N55. Possibly they were wrong including me. However there is a twin turbo version of the N55 too.

I'm not mad. But if you don't know what you're talking about... what are you trying to prove? You're celebrating stupid and propagating it... no one comes here for misinformation!?

You are wrong. There's no "if".

I was wrong and I'm just not afraid to admit it, that's all. And usually try my best.

That blows my mind!

O2 sensor for the X4 has been installed. No problems thus far. $350 for the O2 sensor, $280CDN in labour (2hrs).
