    Found THIS under the hood today... wtf?

    Did a quick check under the hood this weekend and discovered this wire “chewed” right at the damn sensor (or whatever it is).

    Cant’t seem to find it on oem.com; what is this sensor for and what is it called? Assuming it has to do with oil.
    I’m not sure how far back I’ll have to go to replace this wiring.

    Looks like the wiring harness is factory sealed along with multiple other leads... and the sensor doesn’t seem to have enough for me to solder it back on.




    Wire appears to be chewed, but I don’t think it was.

    Not sure if soldering would change the performance of that sensor either, might be a waste of time.

    Any help, I mean ANY light that can be shed on this, would be greatly appreciated!!

    Soldering or crimping isn't a problem, it's just a switch. Try opening the connector if there isn't enough left.

    It is the low oil pressure sender.
    The dealer sells wire "pigtails" with the various connectors(inside the plug) to repair this. A tool is needed to release the old wire. Seems you are also missing the rubber sealing boot. http://bmwfans.info/parts-catalog/E3..._contacts_elo/
    Or, you could simply splice an entire plug sourced from a wrecker. This style plug is used in many places on many BMW (and other) cars, mostly using both of the two wire positions available.
    Send me a PM if you have trouble sourcing, I have lots of this stuff.

    Okay, I just pulled it off. Doesn’t look like it comes apart, but I haven’t investigated that closely yet.

    Now I’m getting it... thanks.

    I need to release that “catch” on the inside of the plug-within-the-plug and back out that female connector, then solder a wire to it. Then reverse the procedure, and solder the other side to the existing wire harness.
    The light bulb came on as I was reading your reply! Didn’t realize the pin connector wasn’t a permanent part of the plug. Lol

    Must be a squirrel with a Toyota back ground. My cousin’s tundra’s wiring was chewed up as well because Toyota had used an eco friendly soybean formula on their wiring insulation which attracted rodents
