Do you have the amazon link to the specialty socket used for the the torque wrench in this video?

Quick question: My 97 540i is not throwing any O2 codes, my CEL light is not on, and she's running great. I went to get California's wonderful SMOG and passed every thing except NO (PPM) at 15MPH. My question is could the pre-cat sensors be bad even though no codes thrown, causing this condition?
NO PPM? I have no idea what that means. Sensors can be bad without throwing codes... but I would Google around to see what causes that.
Hi guys, you guys mentioned to reset the ECU, how would I do that on my e39 540i (she's a '97) after I replaced all 4 of her o2's sensor.
You'll need a scanner or something to reset the codes.
If u don't have the tool, disconnect the battery overnight

how many cats this car has and where they are located? does it has 4 cats two connected to the manifold and two underneath the car?
There are two cats, one on each cylinder bank, located AFTER the headers and behind the transmission.
Any plans for getting a car lift? Suppose your garage might be on smaller scale of things, but it really makes jobs like these a breeze.
Not when I am about to move. Later in life I would love to though!
I just replaced the spark plugs and the ignition coils on my e39 and I got check engine and cat red flashing code and misfire on cylinder 8 with fuel cutoff😭😭 someone help please
Clear the codes and see what returns.
Is p0420 normally for post or pre cat? I have an 01 m5
According to a brief Google search, P0420 means "Catalyst system efficiency below threshold (Bank 1)". I would start by replacing the oxygen sensors on this bank. If the code returns, you likely need a new cat.
Does this cover P0131 and P0151?
Those look like generic oxygen sensor codes. I usually recommend replacing the O2 sensors at this point.
Guess ill do all 4, thanks for the video fellas
Hi I have a question. My Son gave me a 2001 BMW 540i. I had went to Walmart and when I got back in the car it didn't want to turn on. I tried and tried. But I had to get it towed. Two days later I went to go and start it up it crank up but I smell gas and the check engine light came on. It seems like when it gets hot it shuts down. I went out today to start it and now the check engine light is off.
did you get help
Can you please tell me how to fix this problem. Thank you so much
Fix the oxygen sensors? That's what this video is about.. please watch it.
Lolz. Really, my face hurts. Anyway, thanks for the awesome video, as always.
Spud wrench gets them out pretty easy.
It seems like the correct sized open end wrench would work, no need to spend money on a single use tool.
Nice narrative, but you really should wear some eye protection.
Dude you skip the most important think to mention wich one is babk1 sensor 1 an sensor 2 and bank 2 senser 1 and 2 👎 this video is not really helpful
Bank 1 is the passenger's side cylinder bank (left when facing engine from front of car).
lol my whole bung fell off randomly at the weld. Rip
Same, lol!
