here is a page that I think better showcases what I may be looking for:

Last post by Drillbit_97 - 02 September 2024, 10:48 PMHello wow was not expecting quick reply... it appears you sent me a link to a W126 linkage page.. not sure how to navigate that site but the part I need is hard to find because from what I can tell it is only used on the 78-80 W116 300SD making it a real unicorn.

Test Drive / Re: My new (to me) 280se
Last post by Drillbit_97 - 02 September 2024, 10:42 PMwow really nice colour combo really like the interior... never really looked at the data card for my car can you link me the chart where you got the codes/meanings... 870: Electric seat heater for left front seat.... this one i didnt even know was an option for w116...
I always think of these cars as the built to work model even the w126 added motors to seats and stuff like that I find you set and forget those things its just one more thing to fail IMO. love the w116.

Mechanicals / 80s 300SD throttle linkage / r...
Last post by Drillbit_97 - 02 September 2024, 10:32 PMHello All I am new to the forum and happy to be here and collect info and contribute where I can.
I purchased a 1980 300SD about a year ago. It needs a lot of work but I did not want to shy away from it.
I live in canada so the winters are rough, I bought the car of the original owners son for $1200 Canadian (around 900 usd) bought the car not running but i was not worried fired up first crank
. it sat for about 12 years in the elements cleaned off a few times but never used for 12ish years.
as a result the linkage was solid so about 2 bottle of pen oil and 30 minutes of loosening and it is now back to working. I then drove the car for about a week small trips as a test trial and noticed one day a fuel leak. one of the lines was removed and I noticed that the linkage had this rubber that is basically gone at this point. I am unsure if that oil I was using burned it up but if I drive it now it will force the fuel lines off injectors. Have not really had time to spend to fix the car lately and admittedly haven't drove it since.
I was wondering if any of you know where I can get a replacement part, if you do not know what I am referring to here is a link to a form of what It should look like
https://forum.w116.org/mechanicals/1979-300sd-throttle-linkage-quesiton/
months ago I found a form with a diagram but I can no longer find it again... but I found what I wrote down as a part number from a print out : A 617 072 01 50 (Bushing)
The car has many other issues I need to address just to name a few:
water leaks/ seals (likely sunroof seal)
small hole in floor below driver seat (caused by water being trapped below seat frame)
Guage cluster issues (RPM,fuel already had to bypass POT for backlights)
Possible fuel sending unit...
relay glow plug circuit (worked for a while and became stuck on unsure if its cluster issue)
A/C + radio/extras
windows (regulators?
driver works, passenger half down, pass rear no movement, driver rear moves down but knocks on when at top... might not be an issue)
I think I can also buy another car a 74 (I think 280s) that I can steal a lot of parts off of interior wise, don't know if I should just spend a grand to buy that and not worry about finding some of these parts.
if anyone has recommendations for radio upgrades that would be great, want to keep it period so I was thinking of upgrading to the newer late 80's early 90s grand prix (simply for memory FM stations), or a period Alpine or Nakamichi if I could get one. also speaker brand that is not bassy.
my priorities right now are the linkage, floor, guage cluster. the rest can wait a bit especially as I have time till next summer now.
I am only 20 and I am a student and am working at a coop job and have other responsibilities so this keeps being pushed back and back. I just dont want to go another year without doing these repairs, even if I do one repair per weekend its progress.
Thank you for your time any reply is appreciated

Test Drive / Re: My new (to me) 280se
Last post by lowrange4wd - 02 September 2024, 07:19 PMNo, it's the standard fabric in the Moss green color. It's in pretty good shape for being 45 years old though. The dash has some cracks which I plan on addressing but not for a while. There are a lot more things that need to be addressed first.

Mechanicals / Diode and Resistor in Instrume...
Last post by mummyjohn - 02 September 2024, 06:51 PMI'm replacing the left-hand instruments (the ones that show the vitals) as my oil gauge leaks. The new one I picked up is almost identical. In these pictures you can see the original gauge (first two pics) vs replacement (final picture). Numbers printed on them are
What's interesting is that resistor + diode you see on the board underneath the gauge face; they are absent on the replacement unit. I circled them on the circuit diagram. Can't see what the purpose of this is...is it what makes the brake pad light glow dimly when the key's in position 2 but the car isn't started yet? I assume I can put this new gauge in there without losing anything important?

Mechanicals / right colours fuel pump relay ...
Last post by TD - 02 September 2024, 04:23 AMHi everyone,
I got a mercedes w116 450se from 1979 since half a year. It runs smooth like butter, but I got a slight problem. When the ignition is turned on, the fuel pump keeps on running. When I opened the fuel pump relay, it seemed like it was worked on. Now I doubt if the right colours are on the right spot.
Someone who knows the right order or, even better, has a picture of his/her fuel pump relay?
Thanks already!
