"63" engine hesitation

I started a thread on the E63 board regarding my car when I give it gas...off idle....there is a slight hesitation. Come to find out....quite a few of us E63 guys have that issue. Just wondering...are any of your vehicles having the same issue,,,since we have essentially the same engine??? The hesitation occures just off idle,,,when you stop or slow down,,,and then give it a little gas.

Haven't noticed that in 3,000 miles. Is it there from day 1? AS

Some of us got the hesitation when we had our transmissions/engines re-flashed....some like mine, has been since the car was new....we have a good idea that its ECU related, but for you guys not to have it and we do is strange........like I said,,it happens just off idle when you come to a stop,,,and then accelerate,,there will be a slight bog,,,then it just jumps as it catches on........

No hesitition on mine. I'd suggest you reset your ecu by turning ignition key to second position with accelerator pedal to the floor for twenty seconds, then don't restart the car for a few minutes. This should reset the ecu. This has worked numerous times for me on other AMG cars.

Thanks for a helpful suggestion, however, we have tried that...and it does not work. There was a flash that was done to our engine that somehow gave our cars an off idle hesitation. So somehow it does not affect the BS, or the CLK63, but it does ours.....hmmmmm!!
