need help. 1982 300d turbodiesal
I love my car but the only gauge that works is the gas gauge. The brake light is always on. Air conditioner doesn't work. Car doesn't turn off when I pull out the key so I have to open the hood and manually turn it off. Trunk opens once in every one thousand tries. Sometimes locks are funny. How do I fix it?

When's the last time you changed the blinker fluid?
That's alot of problems, most common for these cars. She can be saved.

Owner of 1982 300d turbodiesal
I wish I lived near you. I live in California. Yes, you are all right it isn't a gas gauge. My diesel gauge is the only one that works. The light is the light that is illuminated when you normally go to drive but leave the e-brake on. I have not changed the blinker fluid since I got it about a year ago from my dad. How would I go about repairing the vacuum system?

The search tool is your new closest friend.
Use it to find threads relating to your problems, you will find alot of useful information. I disabled my locking system, that ended my vacuum problems. I've also had a few fuses pop and kill my instrument cluster. Could be the ground as well. You need to change that blinker fluid as soon as possible. It is the number 1 killer for diesel engines.

Well, in terms of gauges...theres a great thread on removing the gauge pod...Id take a look behind there for broken or loose wires. Not to insult you but also check fuses...sometimes those euro fuses look good but have a hairline crack in them. The Gauges are relatively simple devices...if theyre bad, repairing or replacing shouldnt be a mind-blowing task.
Alright, now we have the IN-Famous engine shutoff problem. The Merc Diesels relied heavily on vacuum for functions...including things like shutting the car off, locking the doors, and brakes...this is where you go to Sears and get yourself a Mity Vac if you plan on keeping this car a while! (trust me, its a great investment)! The vacuum pump sounds like its working because I assume you can stop fairly easy so lets isolate the shutoff valve! Diesels need their fuel shutoff becasue they dont rely on a spark for their life...therfore, Merc used their vaccuum pump to literally "suck" the fuel valve shut. This is a brown vacuum line on MY car but it may be the same on yours...if you wanna try this...disconnect one side of the line and literally "suck" the valve closed with your mity vac or your mouth. If it doesnt hold a vacuum...bad valve ($35 on this website)...if it does hold vacuum...try to isolate the circuit that may be leaking. Look for cracks in lines, broken lines, worn out rubber boots, or missing lines all together! Do a search for threads here, visit the DIY section or visit Diesel Giant.com for a great list of DIY tutorials with color pics for your car. I BELIEVE you have the vacuum pod on your car...its by the fuel tank...if this is leaking it wont hold the vacuum needed to unlock or lock all your doors...also a vacuum leak in the system would drain the vacuum from this. Dont forget to make sure your locks are clean too (also, a great thread for the cleaning of these locks). Search around...we all have seen these problems! |

hey we are in the same boat with my 1984 300D
brake idiot light wont go off only gauge is the fuel gauge and ha i'm rockin better than you my speedo will occasionly work and i do have a slightly cool AC not worth a damn in OKlahoma. and my trunk opens smoothly. and today my car started the no turning off thing so if i come across any information or solutions ill let you know, I know how you feel but just keep in mind that "this too can be fixed" ive considered ripping out the whole gauge panel and replacing with good ol Auto Meter gauges

thanks a lot. All your comments have been really helpful. After I finish finals I intend to fix everything. Also do they have online manuals for mercedes or do you have to pay for them?

Which brake light are you referring to? The red one, parking brake on, and low fluid level, or the orange one, low brake pad wear indicator? A/C, normal. Engine not shutting off is a vacuum leak somewhere, or failed shut off valve. Trunk opening, depends on the lock position, does it open any time with the drivers door unlocked? Spray some lubricant in the lock, and work the key back and forth.

That is the red one. First thing to check is brake fluid level in the M/C.

A tool called a Mity-Vac, or something similar. Hook that up to various vac lines, see if it holds vacuum.
There are many, many lines to check, but start with the pump itself. You may be able to do a site search to help with different sections.
