Test Drive / Re: Just bought a 450SE ;D
Last post by ptashek - Today at 03:30 AMWelcome to the gang. She looks like a fine specimen, nicely done! Now to your questions:
- power windows are generally iffy on this model; this is due to poorly designed window regulator mechanism which over time bends itself out of shape; pre-death it typically emits clicking sounds as the gears jump; yours might have a motor problem though - can be fixed/replaced with some patience; should be covered by the service manual
- lumpy idle - I'd start with the quickest adjustment, which is the idle screw just under the air filter snout. If that makes a difference on a warm engine, the next thing to check is the AAV as already mentioned - they have a tendency to get stuck open if the car hasn't seen much use; once of the car testing and fixing it is easy: https://forum.w116.org/mechanicals/is-my-aav-in-order/
- no velour - I'd call that luck! Unlike on the W126, on the W116 velour is of terrible quality. On my W116 velour was worn to bare threads at 60k miles.

Mechanicals / Inside door hinge rotated and ...
Last post by 1980MB300SD - Yesterday at 11:15 PMHi,
I was greasing the inside hinge where the pin is, and I accidentally rotated the inside hinge to get grease in and seem to have locked it. I was of the impression that this was pure fluke. So I went to the other rear door and slowly moved it to see if it does the seem and it got locked too. This is so silly of me.
Does anyone know how to move the hinge back to its original position? Both my doors don't shut and I hope that there is a simpler solution than taking the door panel out and seeing if I can move it back to its original position.
Any help is greatly appreciated!!

Interiors & Exteriors / Re: Rear glass
Last post by HJSFNASDFJA123 - Yesterday at 10:51 AMFinding replacement auto glass can be a challenging task, especially for older models. If you haven't had any luck with local sources, you may want to consider contacting specialized auto glass shops that deal with vintage or rare car models. Additionally, online forums and communities dedicated to vintage car enthusiasts may be a helpful resource for finding a replacement rear windshield. While importing new glass from overseas may be costly, it may be worth considering if all other options are exhausted. However, I would recommend reaching out to a trusted auto glass specialist for advice on the best course of action. Good luck with your search! For anyone in the Fort Collins area looking for window repair services, be sure to check out https://www.cracksandchipswindshieldrepair.com/. They offer high-quality and affordable auto glass repair and replacement services.

Mechanicals / Re: Glow Light Still Flashing ...
Last post by amilio - Yesterday at 10:13 AMHey all, thanks for the replies
My car came with the newer style pencil plugs stock, before I replaced them this past December (with BOSCH plugs), they had last been done in 2009. I'll look at the wiring, and I will have any shop I take it to check the glow plugs for functionality. I would do it myself, but the car is currently in my sister's care back while I am in Washington DC. These plugs are wired in parallel as opposed to the "in-series" wiring of the loop style seen in the link.
As far as a fuel issue, I'm not sure what the issue would be. There aren't any issues with fuel delivery after startup and the glow plug light flashing after an attempted start leads me to believe that it's an issue with the glow plug system, as the relay seems to be detecting some sort of anomaly still. That said, if there are any specific fuel issues that might lead to this behavior, I am happy to troubleshoot them. My primary and secondary fuel filters are relatively new.
This behavior also seems to be somewhat random; the start up yesterday morning was rough, but then after sitting for several hours during a cool day, it started as normal. I've never had electrical issues with the car before so I am hoping this is isolated to the glow plug system.

Last post by TitanBenz - 30 March 2023, 10:33 PMQuote from: daantjie on 30 March 2023, 10:04 PMWelcome, nice findBased on model year this should be KJET.
Sounds like you have a lumpy idle which can be a myriad of things unfortunately.
Start simple and make sure you have no vacuum leaks. Also how old is the fuel in the tank? KJET needs pristine fuel to run right. Any gunk in the tank and fuel lines will leave you pulling your hair out.
Could also be the auxiliary air valve stuck open, a very common problem leading to overly lean hot idle.
Might just need the idle screw adjusted or the mixture at the fuel distributor but usually these can mask other issues so best to start simple.
Hi Daniel,
Thank you for giving me somewhere to start. Will start investigating and put up a post in mechanical subforum, and I guess go from there. Cheers!

Test Drive / Just bought a 450SE ;D
Last post by TitanBenz - 30 March 2023, 08:30 PMHi everyone,
I usually hang out in the benzworld forums, I am an avid car enthusiast with 1x W126, 2x W140, 2x W220, 2x C215, and 1x W221's. I have finally added a W116 to the family and will probably be in here asking questions and getting acquainted with it all. Purchased her the other night... a 1978 450SE with 107,000 km's on the clock. Needs a clean as has been sitting in a garage. Was quite dusty... but it rained and washed it all away. I can now put some photos up. Will detail her over the weekend.
- Car surprised me as it has no rev meter, just has a big clock (haven't seen this before, is this normal?)
- Only has a driver side door mirror, no passenger side mirror (Can I retro fit one?)
- Has a navy-blue checkered fabric interior, wasn't aware this was available on the 450 (always wanted velour but will have to make do).
- The rear driver side window won't go down and there is no motor noise...
- Aircon compressor doesn't have auxiliary belt connected, so need to investigate why.
With the engine, when it's cold everything is fine, but once it warms up the revs are low and idle is lumpy. Yet when you accelerate everything is fine. Anyone have any info on how to adjust/ fix this?
Looking forward to learning about the 116 from you all and thank you for your assistance in advance.
Thanks
