Question about 2001 Mercedes-Benz C-Class

1 Answer

2001 mercedes c240 has a really rough start but when the car almost dies I turn the car off wait 3 seconds and it starts perfect. Next comes the issue with having to warm it up before driving anywhere because it will not go over 15 to 20 mph. How do I judge what the real problem is. It feels like the car is not getting its correct intake of gas or pressure to give it gas.

Gasoline- thank you. Warm up is not an issue like diesel is. Sounds like the choke is is either wide open or over choking. With the engine cold, remove the air cleaner and note where the plate is at the opening of the carb. If it is wide open then without touching anything else and engine not running, step down on the gas pedal and see if the choke plate reset itself to restricter the carb inlet. If it didn't, then take some WD 40 and spray the linkages and the rod ends holdin the choke plate.By hand work the plate and linkage holding the gas open at the carb. Then set the plate to wide open and do the gas pedal thing agan to see if choke sets itself back to restricting the carb intake. If it does, start the engine and as the engine warms upm the choke plate should start opening on its own and you are off and running. Roitine question. Is your air cleaner clean? If the choke plate needs adjusting. get back to me. K? Good luck Remember to press the gas pedal down once before cranking. That sets the choke for cold start. Hope this helped you Good luck Note, the WD40 won't hurt anything but avoid spraying with engine running or when engine is hot..

2001 c240 battery/alternator - visit workshop light


This is normally a low voltage from the alternator condition. Hook a voltmeter to the battery and note the reading. Should be 11.6vdc to 12.2vdc. Start the car, after a minute or so it should be around 13 to 14 vdc., if not then the alternator may be bad

Doesn't start on first turn, by 2nd or 3rd starts. Idles rough.


Battery should be around 12V the alternator puts out 14V. Sounds like a fuel problem, leaking injectors or injector's O-rings. Weak or faulty fuel pump, clogged fuel filter, faulty fuel regulator. Try this, when starting the car while cold. Put the key all the way to the ON position, wait five to ten seconds then crank the car to start. It should start the first time the longer you give it the more fuel pressure there will be to start the car.
