Auto Hold/Parking Brake

[Bill_the_Bear]

Sounds like a whole lot of faf for an extra 1,400 smackers!

Cambridgeshire is flat seems unlikely I'll ever have to park in a tight space on a hill.  In 10 years I think I've only ever done this once while visiting someone.  However, if you live on a hill and have no off street parking it might be an issue for you.

What we do have in Cambridgeshire is the A14 on which I do my commute.  I spend about 50% of the time in stop start crawl, and the commute is about 90% of my week day car use.  Near the end of a commute my left foot is sometimes pretty sore.  For me, DSG and ADC are the way to go without a doubt.  If I'd gone manual I'd be regretting it a week in.

Talk of the devil... just had an alert email at work: incident at M11/A14 junction.  Great.

If you need to press the button to disengage the auto hold. On the tiguan ive got a button and if i need to roll back or forward i just press it to turn the auto hold off. People are getting carried away with this. Its easy, non obtrusive and a great piece of tech.

Yeah I hear ya' Bear, just raggin'   If we're in a lot of stop-start and commuting, I'd have gone DSG as well mate.

I have auto handbrake and hill hold on my  audi Q3 s tronic never had any problems  rolling back on hill starts , even if you disengage hill hold assist the car still stays there for a while .
or you can just engage the auto handbrake to stop you rolling  back which automatically disengages when you press the accelerator as long as your seat belt is fastened ,
. I think having both just complicates the issue ,and as said before you have to put it into park before the key comes out , on keyless I presume you cannot turn the engine off until its in park

Been following this thread with interest, I wonder if anyone can clarify something for me.

I've seen mentioned about the Green hand brake indicator appearing (instead of normal red one) when the auto hold is engaged and that you could take your foot off the brake and the brake lights remain on.

Is the auto hold then using the brakes or a hand brake?? (all be it, the hand brake is a button press in this new GTI not a handle).

I ask because I have "hill hold assist" in my current audi and it has a conventional hand brake. When I stop on any kind of upward incline I can take my foot off the brake and the car stays in place (no hand brake manually applied) and when I pull off, once it hits bite point it releases the brake (effectively like lifting off brake pedal) and it moves off nice and smooth. So my auto hold is using the brakes to hold the car in place not the hand brake (as im not manually applying it)

I've seen suggestions in this thread that when you get to your destination you just stop and the brake engages and you can get out the car and away you go?? Which to me seems to suggest the auto hold isn't keeping the brake pedal pressure applied, but rather its putting the hand brake on and off all the time, but if that's the case then why do the brake lights stay on if its the handbrake that's holdint it?

If the auto hold is just keeping the brake pedal pressure applied, surely when you park up you would click the hand brake button and not just get out etc?

Thought I'd chime in, if you don't mind an interloper.

The handbrake may be an electronic switch in the car but underneath there's still a mechanical system applying the brakes. In this case though it's using electric motors to apply the brakes. Personally I hate this idea as there is more complexity and hence more to go wrong. And a computer is hooked up to it all so who knows what could happen.

I believe Auto hold uses the ABS unit to maintain hydraulic pressure in the brake lines until you drive off, so from a mechanical standpoint is a separate system to the parking brake. I also believe this is the mechanism used with the DSG hold function. It is far safer than a traditional handbrake as braking force is applied to all four wheels and thus you have twice the redundancy.

As for failure, a traditional handbrake fails "off" when the cable snaps, so the electronic parking brake is no different. I'd guess there is the possibility of it failing "on" which could leave you stuck, but it depends on the motor and mechanism as to whether this would happen.

I don't understand why some of you are getting worked up over this 

Joe gti and mcmaddy have explained its a piece of cake, if you're so concerned why did you order the car, you knew it came with the system.  I get you want to alleviate any worries but until you get your own car from the dealer going over and over it ain't going to help you.

Take a chill pill, be  when you get you're car you'll have is sussed in no time.......just saying

totally agree. couple of weeks reaching for the non existent hand brake and you'll all forget what the worrying was about. next you'll be asking about the intermittent blip of the brakes when your driving that primes the discs and pads  oh just so you don't panic you can't feel a thing and the car does everything for you

I love new technology so i'm really looking forward to it along with the keyless entry

I thought it was more discussing than worrying.  I like discussing.
