My 807 HDI doesn't start in very cold weather. I have read somewhere that there is a problem on these cars that when cranking in cold weather, there can be a voltage drop to the fuel system I think it said. This seems correct because if I release the key momentarily before I would expect it to start, it will start. The battery is the correct amperage and turns the engine over fast enough and for a long time if required so I am reluctant to fit a new battery as the fix suggests. If someone knows of this problem and the system that is effected, I would really appreciate the info because I would like to look into the possibility of fitting a DC-DC converter to up the voltage slightly. Wiring info would also be great, Best Regards, Robert.
I had a problem with my car not wanting to start in the cold. It was then I learned about CCA (cold cranking amps). I lived out west and had never heard of cca. You said your amperage is correct so this is prob not your solution. I purchased a battery with high CCA and my car starts every time now. Last week it was below zero and it dragged a bit when I first tried to start it but then started. The higher your CCA the better. Cost a little bit more but so worth it.
Testimonial: "Thanks for your rapid reply and I will look into the CCA for the car. Best Regards, Robert"
My 1997 Mercedes c230 won,t crank it will turn over and fire once and I will have to try it again , I have replaced fuel filter fuel pump fuel relay an fuse replaced crank sensor none make difference
SOURCE: Engine won't start. Dash lights flash rapidly when key turned.
the battery says 12 volts but may be dropping to 4 or 5 under a load...i would suggest jumpstarting the car and see what happens.the battery should read in the high 12 volts and not less than 9.5 under cranking. the dash lights go out on your car when starting,and the alarm will go off ,and disable the ignition if the voltage is too low in cranking the car because the computer will shut it down and activate the anti theft.....check your battery posts are tight. best of luck
SOURCE: mercedes E300 turbodiesel, 1999, is poor to start
Yes sir , you have a failing valve, soon it will snap in two....please have your head checked. You can do this yourself by placing a long-handed screwdriver , business end down to each cylinder while pressing your ear to the handle(while engine is running)...you will notice a definite difference when you hit which cylinder has the bad valve. Also makes sure the egr valve is clean and your exhaust recycle valve is not stuck.( located in the crossover pipe)
