The thing I've noticed regarding the auto handbrake (I've got a manual gearbox) is that if I don't use enough accelerator pedal (IE, just the tiniest bit to stop the revs dropping when I bring the clutch up) it doesn't always release. I'm guessing, but it might be some sort of safety thing that it needs quite a positive input to release the handbrake.
Might be worth trying it with different amounts of 'vigor'. Admittedly I don't know how this would transfer over to a DSG (both testing and how much gas you need to give it) but may be worth a try?
With DSG, you just need the lightest of taps on the throttle pedal to release the Auto Hold, then if the gradient is suitable, the car will creep just like a torque convertor automatic.
We might be talking about slightly different things here - I'm focusing on the Auto Handbrake, not Auto Hold which (I think) work very slightly differently. Does it seem different if the handbrake is on rather than the auto hold? My Auto hold on the foot brake needs way less encouragement than my auto handbrake to release.
Maxie - I don't think you're wasting peoples time, hopefully we can help.
William - not got it yet, probably the new year now anyway as I'm away January-May so a little wait yet for me. Definitely getting one though.
