Spotted something weird over the last few days. I park on my (flat) drive each evening, put the handbrake on by going into Park, pressing the brake pedal and holding the park brake button up for about a second. I get the usual whirring for a second and all seems normal.

Now I notice in the mornings that I turn on the car, put my foot on the brake pedal and move into Drive, it seems to put the hand brake on a bit more! Even though I still have my foot firmly on the brake pedal, it seems to do this. So when I do then put the parking brake off, it has to fully unwind from the "extra brake" position.

I guess if I change my order of things to: "foot on brake, release hand brake, move to Drive" then it doesn't do this. I suppose it's upping the brake pressure to ensure that even downhill, when I release the foot brake (in Drive but handbrake still on), the car won't move?

Has anyone else noticed this? Or am I the only one in the world to do things in this particular order? :)

Errr I'd never noticed to tell the truth! I do exactly what you do, and I've never really listened to what it does, I have to reverse off my drive rather than go forward. I'll listen next time :)

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.

OK, I have been listening to mine, and assuming the car is powered up, with the handbrake on, then when I put it in gear (D or R) there is a short whirr from the brakes, then when I either pull away or let the brake off manually there is a long whirr as they release. That short whirr could be one of two things; either adding an extra bit of tension to resist the movement of the programmed 'creep' when you put it in gear, or some sort of 'pre-arming' ready for releasing.

Ah, so it's not just mine then. I think it's adding the extra bit of tension (like they recommend when leaving it on a steep hill), as it then takes longer to disengage than it normally would. Thanks!

So you don't get a little whirr when you go from N to D or R after starting up with the handbrake on?

I do, yes - I put my seat belt on before moving out of P (bad habit not to IMHO?); also the car should never really be in N anyway, should it? I can't think of a reason why it should exist at all, really, except for towing.

A hypermiler will use N on a downgrade that is not steep-enough to use regen without slowing unacceptably. So rather than having the accelerator down lightly to keep regen off they can move to N. That said, it's a considerable pain to do, and so realistically I must agree that N will only realistically be used for towing.

I could not let this go by without checking :) And I can confirm my 2012 gives a little whirr when I go from N to D or R after starting up with the handbrake on.:D

Thanks Gary :)

Using N in the way mentioned above is rather dangerous as you shouldn't be shifting in and out of N while driving; while I agree it's not as dangerous as putting a manual car in neutral and coasting, you are still moving through the gearbox's settings when you should be concentrating on driving, and it means (more importantly) you cannot suddenly accelerate out of trouble because you're not in gear. A good hypermiler will use the accelerator pedal to achieve the same effect...

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.

Always assuming you have your seatbelt on. Doesn't work if you don't. Can get messy. (No personal experience thank goodness). I love this feature and am very disappointed that the change to a foot operated handbrake in the Mk2 means that it is no longer available, AIUI.

Frankly I think the electric handbrake is a ridiculous anachronism. On a car where everything is optimised for using minimum power, to replace a time-tested simple mechanical system with something that uses power and could therefore stop working at some point is plain stupid. I've no idea why car manufacturers started doing it - just like forward-opening rear doors (which are impossible in tight car parks), it deserves to be consigned to history's dustbin.

All just my humble opinion of course :)

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.
