Cant really say I have noticed but like Mike I reverse out of my driveway and it is a very slight slope. The vast majority of the time I just let the handbrake automatically disengage when I go to drive, either forwards or in reverse.

I don't remember hearing any additional whirr when pulling away in D or R. Just in D the back end drops slightly then the handbrake whirrs off.

My car does this too I have now confirmed so it looks like it is a TADTS.
I had not noticed before because my routine for setting off is:-
Foot on the brake, power up, release handbrake, select R or D, release footbrake and off she glides.
I tried selecting D before I released the handbrake and that is when I heard this extra whirr too.

You do realise that the electronic parking brake will auto release when you try to accelerate.

i.e. From parked (overnight) with handbrake on and car powered down, Get into car, foot on brake pedal, power car up, when ready move foot from brake pedal to accelerator and depress, electronic brake will auto release.

That makes hill starts VERY easy as it works anytime you have the handbrake on and want to move either forward or reverse.

Yes, I use the auto release when actually driving and at junctions any time I use the handbrake as it makes take-off quicker as otherwise you need to use the footbrake whilst you release the handbrake. But under these circumstances the car is already in D and so I had never experienced this additional whirr. It is only when I varied my normal procedure and selected D before releasing the handbrake that I heard it.
