Oxygen sensor information

[Jlaa]

Adding to the tribal knowledge here from @gsxr's original info:

000-540-29-17 / Bosch 0-258-003-236: Only for 1990-91 Euro models to B565713, not sold in North America - see post #35 for details)
000-540-26-17 (1992 USA model years)
000-540-45-17 (1993-95 USA model years)

.... However, Bosch also has a few sensors with the proper connector. None are exact replacements, but they are close enough to work just fine at less than half the cost of the OE sensors.

Bosch # 13429 (or 0-258-003-429) is available for approx $75-$100 USD. It has the 1992-style tip, and the wire is only slightly longer than the OE sensor.
Bosch # 13326 (or 0-258-003-326) is available for approx $75-$100 USD. It has the 1993-1995 style tip, however the wire is significantly longer than the OE sensor.
Bosch # 15058 (or 0-258-005-058) is available for approx $60-$100 USD. It has the 1993-1995 style tip, however the wire is significantly longer than the OE sensor. It appears identical to the # 13326 except for the addition of a corrugated heat shield at the sensor.

I have used the # 13429 on my 1992 500E and also my 1995 E420 (despite the difference in tip design, which I think may be irrelevant). Due to the limited clearance between the exhaust system, driveshaft, and transmission tunnel, I am concerned that the much-longer wire on the 13326 or 15058 could be a problem... the extra wire length would have to be tied up and out of the way so it doesnt touch either the exhaust pipes or driveshaft. On a side note, Bosch documentation indicates the # 13429 sensor has a longer life span, 100kmi (160k km). Im not sure what the life span is on the 13326 or 15058. Click here for some assorted Bosch technical documentation.

Note the length of the wire for Bosch #13429 is about 8" long versus ~5.25" for 000-540-45-17 and ~5" for 000-540-26-27.
Also note scratched off MB star and part numbers on the connector.

@Jlaa, note the 4-digit code stamped in the plastic connector. Looks like 0520? If so, that is either May-2020, or the 5th week of 2020. Recent production!

Thanks for the tips. Also ran into an oxygen sensor problem. The scanner began to swear. Then I saw that one of the four legs was broken on the connector. I ordered a new connector, I am waiting for them to be brought from Germany, I did not find a new one in Moscow. I will also immediately buy the bosch oxygen sensor itself. At the moment, there are problems with unstable engine operation. I will put everything in order and look for the reasons. Now it is hot at idle, it does not work stably, and accelerates poorly, as if not a 6.0 engine.
The distributor covers and runners are new Beru (they are praised for their quality, so they were bought when they were still supplied), the wires are Japanese ultra, the spark plugs are original Mercedes

Moderator edit: Additional replies to this post were moved to a separate thread (click here) because the engine operation problems should be in Troubleshooting/Diagnostics.

NOTE: The part number for the plastic O2 sensor connector, which bolts to the transmission tunnel, is p/n: 140-540-03-81 (for USA cars, and late Euro 500E). This sometimes gets damaged and the p/n is not in the EPC. If you break the rectangular rear cover, that is p/n 019-545-32-28.

I recently ordered the replacement plug as mine was broken. 140-540-03-81 was the whole thing, including the rear cover which did not need to be ordered. It only matters as 019-545-32-28 was a mere $3 but $10 in shipping.

Dear collegues. I have a s500 1994 w140 that originally has installed Part number 0005404517 oxygen Sensor. It didnt come Out good after replacing the catalytic converter. Can i use any of the Bosch Part Numbers that were mentioned at the beginning of this thread?-see Screenshot. I installed Bosch universal oxygen Sensor (025886503)that is stated as replacement for my original Mercedes part number. Unfortunately during driving i noticed the lh maximises enrichment correction. I checked with hhtwin and the Sensor Voltage is showing 0,1V, and Not cycling during engine idle. Fault memory Shows No Codes. I'm a Bit confused because my Original sensor hast lsh6 lasered in. The replacement Bosch part has lsh24? Does anyone know If that is the difference that can cause this behaviour? Any recommendations and help is appreciated. Thanks in advance

Yes. Those numbers in post #1 are all interchangeable / functionally equivalent, except for the wire lengths as noted.

Could be a defective sensor, incorrect wiring when spliced in, or a bad connection at the twist-lock. Not sure what's up there.

@gsxr,
Dave, Do we just order what comes up (2344057) when we punch in the order form?

@TerryA - yup, that is correct!

@TerryA - yup, that is correct!

I ordered one.

My Oxygen Sensor arrived today. Now what?
I don’t think I want to change it myself.

I’m at 143K miles in a 31 year old car. I do believe that it needs to be changed and I have no record of it ever being changed.

@TerryA - how much of a rush are you in?
If you are not in a rush at all (like nothing is wrong and waiting a year or two is no big deal … or waiting until something does go wrong …) then we are in the same boat. It will take me some time to move all my tools / quick jack over … at which point I would be happy to have you over for a “drop the catalyst assembly and replace o2 sensor party”

 

[gsxr]

FYI... no need to drop the cat pipe if the sensor isn't seized. But, you don't know until you try.

Hi, Thanks to this thread I ordered a new Oxygen sensor from Amazon, Bosch 13429 for my 1994 E500 http://www.500eboard.com/forums/showthread.php?t=824 Got the car on my lift, found the sensor, and WTF? How do I remove this thing? I don't think a regular 22mm wrench will work. -...

Thanks for the offer. I’m in no hurry. The car runs fine maybe not the best mileage but it’s been like that for a long time. I’ll wait. I don’t want to bungle the job and have to take it somewhere.

@gsxr,
@RicardoD made it look easy. Thanks for posting but I’m still going to wait. Jlaa has a lot of experience with Ricardo. We can fumble thru it together.

What an apt description. I specialize in fumbling through all jobs automotive.

I'm at 150K miles exactly, and am still on my E500's original O2 sensor. I have a factory spare, but have not needed to install it (yet). I did install a new O2 sensor on my M117, at 183,000 miles. Didn't specifically need it, but it was a proactive replacement as part of a Top-End Rebuild.

 

[emerydc8]

I said I would never order again from Rock but this deal is too good! Thanks Dave.

 

[Rouven036]

Got myself also one for the hoard stash. Arrived well across the pond.

@Beater400E @gsxr Thank you guys!! I ordered one aswell on Monday evening and it arrived today (in Germany!!). Now that‘s some insanely fast shipping right there… I am stunned.
