Check for a battery drain ie:trunk light or glovebox light staying on make sure all the door catches are closing properly spray the locks with wd40, Including the hood and trunk catches, check the radio is off properly, You made need to get a electrical drain check done by an electrical expert ? Hope this helps

Not sure what kind of mileage it has, but check your fuel filter. Check air filter too.

Sounds to me like a voltage regulator issue. This is attached to the alternator and monitors how much voltage is sent back to the battery. Any decent parts store should be able to hook up a charging system tool-most common is a Vat-40 and check the system. And they will probably do it for free. If there is an issue with the charging system, then try the voltage regulator first, as opposed to the alternator-there is quite a price difference I assure you. Let me know what you find.

pull the stereo unit out check the rear wires and the rear fuse some times there are 2 fuses 1 for unit its self and another for the amp if its still not working try another cheap radio if that works its the stereo if not there is something wrong with speakers probable worth just replacing head unit will work out cheaper

if its got one it should be at the back of the radio(sometimes inside. wish you well.

sender units ( you didn't bother to mention any specific one) send data to the ECM so that the engine/ transmission TCM can make the suitable adjustment to keep the engine /transmission in tune they will put lights on (ABS-TRACT control )when these sections fail

is your clutch springing back after pressing it? if not it could be your master cylinder or slave cylinder is shot.

In the winter mode it will not go no more than about 10 or 15 miles an hour. Take a look at the owners manual.

Hi Ray This is an unusual problem the gearbox change is controlled electronically so normally the first thing to do is get the vehicle plugged into a diagnostic machine ( this would also normally require a proper mercedes start diagnostic and not a cheap one at the local garage) But assuming it is electronic you have 2 choices the gearbox control module located in the car just below the gear change lever and the main electronic control located in the oil pan of the gearbox not so easy to access, Just a thought have you ever spilt a beverage such as coffee or soda over the gear lever area ? as I have seen this problem before with a lack of gear selection it had shorted the module, So I guess for the cheapest first stop I would locate a second hand module from the breakers yard and try this first it should be a easy DIY anything more will require some proper mechanical skills hope this is of some help, Just a last minute thought have you checked underneath for a transmission oil leak as the oil may just be low this model suffers with the "O" ring around the electronic plug failing and causing a leak its located on the right hand side of the box just above the oil pan at the front edge. Richard (mercedes technician)

first I would check all the parking lights , the other is there are 3 flasher units 1 for left side 1 for right and 1 for 4 ways

does it have a check engine light? You need to have it scanned and yes it could be a mass air sensor, dirty fuel filters and air filters can cause this too.

Sounds like you either have a Electrical Failure that is causing the Computer to not allow it to see the gears.. with a Mercedes, you are going to be hunting this down for a while unless you bring it to the Mercedes Shop. But their system is computerizes and will save you time and money in the long run... SORRY

Had the same issue on 2002 c320 . look at the fuse chart ,find out the fuse # that operate the radio and the cigarette lighter , you have three fuse boxes, engine compartment, driver left knee and trunk on left .find the fuse b compairing the char to the box , replace the fuse . DONE

hmm it could be that they over filled the oil or it bouced up to the sensor

Why not replace the battery ? If not the only other way is with the key on thr driver's door

traction control
The "ESP" system helps correct oversteer and understeer by breaking the inner or outer wheel as needed to get the car back on a straight path.
lets you spin tires

Turn it off with the switch Switch is on the turn signal post or on the steering wheel on most cars.

were talking about the key fob battery.right?? try holding both the lock and unlock buttons at the same time while pointing the key fob at dashboard/drivers side door area.give it at least 10-20 seconds and see if that resets it.

well for one its a mercedes, and two, better refill coolant

Most likely the thermostat is stuck/bad.
