Saying goodbye to my 300e today. What a great piece of machinery it is. 250k miles on the clock. Still runs like a new car. I'm donating it to a veterans organization that helps our current and past service members. Thank you for all your videos. They've been extremely helpful.
@@MMWA-DAVE we are moving from Idaho to Pennsylvania. Wife retired yesterday so we are free. I am in need of a pickup truck. I wish we had access to holdens here.
Thank you for your lessons to teach maintenance and repair of a 1991 Mercedes 300e, and we hope if it is possible to translate what is explained into Arabic
Did one on a mates BMW, Same deal and it was leaking through the switch and out around the pin. Surprisingly for a BMW is was fairly dry underneath lol
Would you please, comment on what size copper crush washer, you used on oil plug. I have the 92, 300e 2.6l I read some use a copper washer with rubber in inner diameter. So, far I have 14×20×1.5 Copper washer. With no rubber in inner diameter. Would, appreciate your help... Thank you, for all your great videos, have learned, a lot from you!!
i just buy the recommended crush washers when ordering the filters from FCP euro. I ordered a bunch with my new sump plugs too. Have never put a lot of thought into them as havent had any issues. If you are having leaking issues and battling with leaks and experimenting with washers, the problem is almost always either the plug or the sump itself.
@@MMWA-DAVE where was it leaking from in your case? I am in the process of dealing with the same thing myself and i am debating if i should just change the two o-rings or just buy the whole sensor and be done with it.
@@arismidos4326 the plastic core that has the electrical pin on it, has an o-ring around it and is staked in, ie never meant to be removed. This is where the leak comes from commonly. This makes the sensor a throwaway item unfortunately. You might be lucky and it be just the outside but this inner one wont be far behind if it is.
Now an interesting scenario happened to me.After fitting the new part putting some new oil i woke up with a leak it looks like its comming from the part where the connector goes in the pin but its hard to say...Any ideas
@@MMWA-DAVE Well ill just order a new hella unit.I dont like that I have to take the oil out again but still better than a leak...Does the rubber o ring do anything than sealing the connector to the sensor because that part on my connector is missing (its broken) until i find a new/used one.
the o ring that is leaking is the one around the staked in plastic pin housing. You have to drill out the stake points then resecuure it some how to do that. it wasn’t designed to be disassembled
this was used on the m104.980 when first came out, it was replaced by the plastic cap on later versions. The plastic cap is all thats available now as far as im aware - it is whats on the new housing i bought for my red car.
This is very standard practice when OEM’s sell parts in their own boxes. They are the same parts MB sells but they are not allowed to display the MB logo or part number. MB makes very few parts themselves, most are made by third parties, ie Hella in this case makes this part for MB.

Glad that it has gone to a good cause and hopefully you will be back in another benz in due course

Hi MM, did the same thing last year, got the sensor for $60 from MB when I was in spain the year before. It was a nice find

Thanks, nice video again!
Hello, where is the oil pressure switch located? I couldn't find it or does it only have the oil level sensor?
Hello, is it possible to replace the switch without draining the oil?
It might be possible if the car was lifted only on one side so the oil was away from the opening. I cant confirm this though as I have not tried it.
ok thank you. I will try @@MMWA-DAVE

What is torque nm for screw oil sensor
Got a w124 94 it's stuck on limp mode any tips?
Why didn't you replace the o-rings on the sensor?
because that’s not where the oil leaks out from.

it sounds like you have a faulty new part. I have also seen this too,

How many kilometers have you traveled with this oil please?
would have only been a couple thousand kilometers. But its been in there for a year.
@@MMWA-DAVE ok bro, thanks
@@MMWA-DAVE Do you have social medias to communicate with you?
Could a bad oil level switch cause my engine oil level light to turn on and off?
Yes. If you are certain the level is correct and the pressure is good.
Theoretically, couldn't you just replace the seal ring ? It's not criticism, it's a genuine question :)

@@MMWA-DAVE I see, thanks for answering
Never seen a filter cover like that in a w124

@@MMWA-DAVE M102 W124's use screw on type filters (as does the W126 300SE)
@@apexantiquefineartmerchant4419 yep i know. I also repeated this exact job on the blue 300e immediately after completing my m104.
Oil looks like new.
it was quite smelly so heavily contaminated from fuel from all the cold starts and short drives i do. Unfortunately everywhere i go is close by
hahaha why did hella sells the original mb part , but grinds op off the mb logo and part code ? how strange ! LOL
