For me, they were a decent amount longer than my original ones. They should work the same as your previous ones, unless the wiring is incorrect. Also, if you’re replacing your exhaust as well and mismatch catalytic converters (high flow for example) you might get a CEL related to the oxygen sensors.
Black wire goes to black wire, gray goes to gray. Then there are 2 white wires which doesn’t matter which one you connect to which because they’re both heater wires to heat up the sensor.
Thanks for this. There's still one big question. Why the customer has to make the wiring in the first place? I bought two lambda censors. Post-lambda has the connector and everything in one piece. Pre-lambda.. you have to cut and build it yourself. What is the idea behing this bs??
Lol no clue. I’m thinking because it’s a universal sensor it’s easier for them to make it this way and let us do the work. This way they can work for multiple applications.
@@josephkessler7222yup. Cheaper for us and them. Getting OEM sensors for bmw is expensive for no reason, cause I can just buy the universal sensor and splice it myself. Takes a bit of time but you save hundreds.
$60 for the universal ones you wire yourself. $170-260 for the Denso that is plug and play. So people wanting to replace 2, could save $200 buying a "universal" bosch set that youd have to wire yourself.
So I didn’t have a CEL prior to doing this because I didn’t drive the car until I was finished with some work. After doing this I drove for a couple hundred miles and got a CEL for an O2 sensor code. I was out and about so I drove another couple hundred miles with that CEL, and then cleared it. So far it hasn’t came back. It’s been about 100 miles since I cleared it.
@@josephkessler7222 thanks. Sometimes people are reluctant to buy this type of Bosch universal sensor (02), despite that Bosch has been well known for its supplies for Bosch spark plugs and the like. Normally this type of Bosch universal sensor would be suited for the pre-CAT sensor type, because of its wire coloring codes which are very important that must match to the old 02 sensor wiring harness adapter. Did you experience any poor fuel economy prior to the 02 sensor not being at good level?
@@ulf-dieterkoepp7865 I only replaced them due to an aftermarket exhaust moving the catalytic converter further away from the original location. I had to use these to extend the O2 sensors.
Only person with a video to do this.
My colors are different.
Are the white wires neutral wires, so irrelevant if you mix them up?
wait, these two white wires you have, does it matter which one you connect? or is it irrelevant?
Irrelevant, just make sure the black is connected to black and grey to grey.
Is longer or shorter cable as compared to orignal sensor, will affect any functioning?

Is it black white and gray and white or how does it go ?

Did it really eliminate your error code - either P0420 or other code?
