500 SL R129 and R 320 CDI W251
Throttle response lag
Hey,
I have a 320 CDI, and have noticed one thing: If I brake say against a intersection, and then goes back on the throttle, I think it takes a very long time before the car starts to accelerate.... if you are driving along, and then step on it, it's quite quick. Anyone else have the same problem?

My GL does this a bit and it seems actually worse after the crankshaft position sensor was replaced under a recall.

My '06 R350 is doing the same thing. I find that if I have it in manual mode, then I don't have the problem, but in auto I do. I have taken it to the shop twice already, but so far all they have said was that my trans fluid was low and that the shift points were off.
I'm still having the problem, so I guess those were not the causes. Anyone else having this problem?

I have a R500 and it is doing the same thing. Also when you drive off in the morning, leave the accelerator @ 30 mph, as the speed slows and it changes gears, it will give you a jerk.
Well, my MB dealer reset the transmssion twice and then it works fine for 2 months. Then the problem comes back and now we are back to square one.
I am taking it in tomorrow and seems like they have to replace the transmission. If that happens, then I will return the car as lemon as it seems you all have the same issues too. I think the 7 speed is not working well with R Class.

BTW, I traded my 05 SL500 on the R500. The SL was having numerous electrical and trim problems that weren't covered by the extended warranty. I like the R because it is much easier to get into and out of for an old guy born in 1947. I autocrossed the R last summer and may do so this year as well, depending on the availability of money for autox tires and wheels.

Keeping it in manual (downshifting manually) as I decelerate solves the problem and I just go through the gears until back into auto. I think the 7G tranny still needs some work, but overall this is my only complaint against my R.
