Hi,

I bought C230 in Feb 06 and recently noticed that down****ing of gears is not so effecient. Once speed go more than 40 mph and then drops to 20 mph and if I want accelerate then car doesn't have enough power because gear stays at high level.I found this by shifting gear to manual mode.

I took car to dealer and they have resetted the whole software who controls the gears part but no help. Now I am told that new software si going to come and then they will put that once it comes from MB factory..

It is so surprising that such kind of s/w needs upgrade etc.....

Anybody faced similar problem???

I appreciate any any commencts and help.

Thanks,
Bjosh

if this 230k is an 01 or later, i'm afraid you're in the wrong forum. try the W203 forum.

as for the kompressor. i have a 230k and I've not had such problems, but if they've reset the ECU, sounds like it'd have to be a more mechanical problem than computer.

I'm so sorrry, but WELCOME TO DRIVING A MERCEDES! LOL! I have the same problem in my w202 as well as all the w203's I've driven. What you need to do is learn to drive your car. I don't mean this as an insult. What I'm saying is that you need to learn how to punch the pedal just right after slowing/cornering at lower speed to get that proper downshift. To help with this, I drive in "S" mode 95% of the time. It will help with the ease of getting the car to shift. I think out of all of them, the 2006 w203 is the worst with this problem because of the 7g auto trans. they put in it. I personally am not a big fan of it.
