Have had an E250cdi sport for the past couple of days and whilst its a great cruiser, and its clear that Mercedes have gone old skool with their build quality (at last), the car has a very disconcerting, and in the right situation downright dangerous, habit of providing no response to light throttle applications from standstill.

If you want to manouvre at parking speeds from rest, press the throttle lightly and nothing ! At least 2 seconds lag before the engine responds, so you press harder to elicit a response and of course then the car wakes up and jumps..... same if you're trying to pull out from a junction... simply unbelievably bad throttle mapping.... I haven't looked on the benz forums but is this a one off on my car or a known issue ?

Car was a 2010 with 6000 miles.... I simply can't believe Mercedes signed this off or owners are not up in arms about it... whats the story here as its unacceptable on a Daewoo let alone a £40k new car?

Is it the same with the autobox in S mode?
Yep it is. I pretty much only drove the car in S mode as C was too lazy with its gear selection for my, er, spirited driving !!

I did try it in manual but not for parking manouvres, only when on the move.

I had a CLS350cdi grand edition a few weeks back which didn't have this problem (its engine was also faaaar nicer than the 2.1 unit !)

Well that's a bit odd as there have been loads of complaints on the MB forums about the 350 autos, which have a 7 speed box. I can't recall seeing anything on the 4cyl/5speed box.

Take it to a dealer and tell 'em it's dangerous.
Interesting. Hmm.... suprised there has not been a recall about this given its so prevelant.

Why not try taking it to your local dealer and get them to check and see if there is and actual fault or not.

The dealers recieve frequent software updates from germany for engine and gearbox control units which can make a significant to the way the cars drive.

At least then you will know if there is an issue with the car or its just the way it is.
Indeed I would if it was my car, but I just had use of it for a few days. Thought it very peculiar for a 2010 car to have such an issue tho so wondered if it was a wider-spread / commonly known about problem
