20 Most Recent 1985 Mercedes-Benz S-Class Questions & Answers


With the little information you provided, My first suggestion in s a faulty pick-up coil in one of the distributors. Because you are missing half of your cylinders, your problem is likely isolated to one of the two distributors. If the Cap/rotor are good on both, the pick up coil (or equivalent) in one of the distributors may be faulty and will cause all the plugs on it to not fire.

It sounds like a vacuum leak. Check all your air hoses. If there is a leak, the engine is getting too much air before the airflow sensor and after the start up boost of fuel to the engine (usually about 10 sec) the engine goes back to normal mode fuel delivery and the engine dies because the air to fuel ratio is too lean. You may have knocked a hose of or torn it when doing the service.

its not a fuse its the flasher relay they are located under the main fuse holder under the hood on the driver side they are square there should be three one for the fuel pump one for the electrical panels and lights and horn and the other is the one for the flashers your better off replacing them all since electrical parts are mostly the same age replacing one may fix that problem now but happens when one of the others goes out and your in the middle of no where in the middle of the night since your going to be replacing one its better to replace them all to save a head ache for later just the same as any car part like the radiator hoses if one is worn and leaking then the other maybe the same but has not formed a hole yet its always better to think ahead then to think about what is going on at the time of the problem just something to think about

Sounds like you have blown a hydraulic hose that operates the top mechanism. You will probably need to find a local mechanic that is experienced with hydraulic operated tops or a dealership. But check you owners manual. Most manufacturers have a manual way of operating the top to allow you to secure it until repairs can be made.

The dealer has some problems with these I think. Bad fuses and such. Check to see if the blower motor is getting power after you turn it on. Check to see if the resistor block (in series prior to the blower motor) is good.

It probably lost the rolling code, you need to find your owners manual and reprogram the system with your garage door opener, or the learning button on your garage door unit.
