kscarrol and alohalc, regarding starting in 1st or 2nd in D mode: Count your shifts starting in D mode. I'm sure I get 5 usually. Maybe it depends on how much throttle we use, as someone else suggested.

Whether in D or DS mode, the transmission will operate in this manner.? Downshifting to M1 while in DS mode will eliminate the hesitation, although manual intervention at every stop is unsatisfactory for most of us.
All versions of the E39 automatic transmission (Steptronic, non-Steptronic, 4-speed, and 5-speed) did this as well.? The difference is that the E39's downshift operation from idle was much quicker and nearly imperceivable.? The E60's downshift operation from idle is slow and noticable.? Adjusting the idle may help to mask the hesitation, but the problem remains.? The issue exists within the ZF 6-speed or the transmission programming.? Perhaps someday we will know the exact cause.

[/quote]The vehicle will start in first gear regardless of accelerator input or the transimission mode (D ore DS) selected. Again, the automatic transmission resides in second gear when the vehicle is stopped and at idle. The exception is when manually selecting M1, M2, or M3.
Put the Steptronic transmission in M1 and pull away. You will notice an immediate differrence with no hesitation.

[/quote]Understood. However, I have not noticed the hesitation in DS mode, only in D mode.

I got my car back. Here is what is going on.
- hesitation is still there BUT when i put the transmission in DS or just manually select M1 there is no hesitation whatsover.
- s/w has been updated to 13.3 I-Drive is noticably faster booting up and when browsing through options now. It feels like i-drive has been installed correctly this time.
- now it takes about a split second to start up the car when the key is turned. must be this new s/w version. it used to be instantenious.
- nav says "next road" now
- steering wheel feels tighter at slower speeds now.
that's all i can think of right now. if you have any questions let me know.
and yes, i am glad i have my 545 back. i still love it and would buy it again over MB or Japanese any day.

[/quote]the dealer told me that everything has been fixed. i really didn't notice any hesitation the day i picked up the car so i thought it was all good.
I'll be calling my advisor and ask him about this.

I had a 7 series loaner recently and experienced the delay from stationary. The explaination to me was that the car goes into a quasi neutral when stationary and when you hit the gas it needs to engage the gear first before moving off.
The gear engaged is first not second it's just the engagement delay that is being felt.
As a matter of interest my 530D always starts in 1st unless you are in steptronic manual mode and you come to a stop in which case the box defaults to M2.
The difference in feel between starting in 1st or starting in 2nd is so big that there is no doubt as to weather you are in 1 or 2.
