Well, there you go.

The passenger side sensor is for heated key locks/washer nozzles. It has nothing to do with OBC temp and does not need to be hooked up. It's also a totally different style sensor if you want to fix that one too.

Here's a shot of the driver side obc temp sensor wiring.

"Unplug it and see what happens" would be the easiest test before "anyone else knew how to!".

I would like to repair that one as well. Would you mind sharing a picture of it as well?

Sure. Make sure you're standing strong or are sitting down, this is revolutionary...

First of all I never had to fix mine, but besides that, ever heard of the BMW ETM? Electrical Troubleshooting Manual?

It has listed every wire, pin, connector, its color(s), junction point,
number in connector, and ...location.

It's the BMW Bible everyone should have. I never had the need to ask anything electrical related, it's all written in detail right there.

Regarding the OBC temp sensor as it's known in the ETM, it tells me it's component "B21", has two pins on connector "X770" and has a brown/grey and brown/orange wire and is located on front left of car. There is also a pic of its location.

Back to you.

What are you talking about? I never wondered about that for a single moment in time. Why would I even do that?

You really think I care if I'm being like or not? It's literally the very last thing I would care about. I'm not here to be liked. What would that even gain me? Exactly, nothing.

Why would you care if I wonder about it? Which I don't?

Having said that, I answered the guy's question, in detail. So what's the problem?

You seem like the person who just never can be pleased. And I don't need to be part of the Bray-Wes bro'ship.

WAIT... you mean no one appreciates him constantly reminding everyone how much he knows about the intimacies of a 28 year old OBC?

I believe when asked about alpine white SMG cabrios, Adrian Van Hooydonk himself simply said "They were the reason I was born."

Those ten examples are the sole reason the ETK was even created. BMW knew the act would serve a higher purpose. The Vatican even went to great lengths to ensure the system ended up in the hands of those deemed worthy and will continue on for generations, should M_Parallel fail to achieve immortality.
