Hi,
The early 300 SL suffered from dodgy HT leads and spark plugs if not regularly maintained, the problem with Mercedes Benz though is that the cars have so many features that it is almost impossible to diagnose without seeing the car. Some things to try (in this order) are : - Spark plugs, Ht leads, remove and clean Distributer Cap, replacement of HFM sensor (common fault), if none of these help then faults have been known in throttle valves and fuel pumps/filters

Happy fault finding

SOURCE: S430 Mercedes - Front end shaking at 55+

It sounds like you have either a broken steel belt in your tire or a worn out idler arm in your steering assembly. Other causes may be a bent wheel, a flat spot on the tire or worst case your brake rotor / wheel hub may be loose. If the rotor / wheel hub is loose you may have severly damaged wheel bearings. Good luck...

SOURCE: a/c fans wont blow

If the fuse is blown for the blower then there is a short, that is not an answer, go to the blower and check to see that the blower motor connector has 12 volts to it when the blower is set to high speed on control, if it does then u need a new blower motor, if it doesn't then the control switch is defective or the blower motor speed control resistor is defective.

SOURCE: mercedes s430 wont start car wont shift out of park

is check engine light on or visit workshop displayed on cluster while engine is running. If so there is a electrical malfunction-although if the linkage is disconnected from the trans to the throttle the gear recognition switch would send an implausible signal and set a code. this code is not a priority code and may not set the light right away. A lot of times one of the linkage rod retaining clips falls off. Look under the car and you will see a rod that attaches to the shifter box arm and to the transmission neutral safety switch(manual valve) arm. It may actually be resting on the ground. If not look and make sure it is secure. Next there is a slot on the shifter wood where you can put a flat blade screw driver in and release the manual shifter lock. Your owners manual will describe how to do this. Depending on what failed the vehicle may be in what is called limo home mode where the trans does not shift out of second gear and the throttle is not very responsive. It will give you the opportunity to move the car to a safe location possibly even a repair shop. The shifter boxes are are a sealed unit with no replaceable parts. They are slightly expensive and require an s.d.s. machine to replace because they must be programmed and version coded. I hope I have been helpful

In cold temp,heater motor do not run


you mean low heat. at all ducts with full fan speed and blows hard,
here is the correct order.
1: engine at 180F or more holding, a absolute must.
2: fan runs at full speed on HIGH, (sounds like it)
3: fan actual blows (felt) at full speed, to any vent, try all vents.
4: now heat, will happen, if not, the dampers are closed or wrong.
damper can be complex on newer cars,they have motor controlled damper servos';

is this just blower fan dead? problem. on high, if yes say so.

My fan won't blow hot or cold air unless i'm driving fast on the interstate


Sounds like your heater blower motor is not functioning properly. At high speeds it's probably drawing air in from the outside then through the vents (defrost, etc.). If blower motor sounds like it's running, then maybe the squirrel cage (heater fan blade) is not spinning and in need of repair or replacement.

There is no heat or cold air blowing through the vents when turned on.There is cold air coming through when the car is travelling fast but there is absolutely nothing when the car slow right down or stops...


Sometimes this is caused buy a vacuum problem. It is not opening the door to let your air in at a slow speed. The doors are opening at high speed due to the air pressure from the outside air. Make sure that the fan is runnig by turning your ignition on but not starting the engine. Turn the fan on high and see if you can hear it. If the fan is running then take you car to a mechanic you trust and have them check the vacuum going to the door.

that model of mercedes did come out with daylight running lights meaning that when the key is on the headlights come on at a lower wattage. and if your bulbs keep blowing i would have the wiring checked out.
