a few questions - PeachParts Mercedes-Benz Forum

a few questions hey guys i'm new. i have a 240d. i just spent about a million dollars in the shop on it, but some things still are wrong. first, it idles really rough and when i start it, if i don't give it gass immediately, it turns off. it also turns off sometimes when i stop. I thought it was a block heater issue, but i don't think they came on these models. It is possible that the last owner just never got one because he lived in texas, but it's pretty hot right now. any advice? thanks

What did you have done? Your problem could be a million different things.
Post what you had done to it in the shop and what kind of shop it was. I only go to MB specialists when I absolutely have to. These cars aren't very well serviced by regular mechanics for obvious reasons. __________________

'06 Ducati S2R800 14k(sold) obscure starting prob the first thing about starting sounded like glow plugs but after it is warm that should not recurr. so how much have you driven it? enough to be sure the fuel is good? did you change both fuel filters? also did you use fuel conditioner and algaecide?

why do you think the starter is going bad? __________________

..I also have a 427 Cobra replica with an aluminum chassis. the problem isn't to start the car; i can do that with a little effort. the real issue at hand is that the car turns back off. i don't know if it stalls or what. it only does it when it's cold, but even after i pull out and get to the first stop sign it turns off when i stop. What do you mean your car doesn't have a tach?

Your vehicle should have an idle speed adjusting knob to the left of where the steering coloumn passes through the dash. I don't think this is for use in warm weather, really, but I suppose you could try cranking it up some and see if your engine still cuts out.

Have a reputable MB shop check the compression on your engine.

It's possible your engine is just getting really bad compression and this is the reason it cuts out at idle. __________________

300SD (parts car) Is your temp gauge reading in the 80C to 100C range after 5-10 minutes of driving?
Your engine may also be running too cold because of a bad thermostat. When I first got my 300cdt form my dad, the thermostat was corroded so much that it stayed open all the time. __________________

300SD (parts car) my model and year doesn't have a tach on the dash. the temp is good also. i think i know what know you're talking about, but i don't know which way to turn it. if i have the car running at idle and turn the knob, will i hear the speed change?
