Sorry guys another question. Having never had a car before with keyless access, I'm debating if this option is worth the £425 Audi are asking for it ? For those of you that have it, how does the locking / unlocking actually work and what are the keys like (i.e. do they still have a pop up blade for emergency use ?) Also, how do things like convineience headlights (leaving home lights) work with this. With the standard locking, as soon as you press unlock on the keyfob the Autolights come on (if you have them), but on the comfort key, when how do the lights know when to switch on or is there a button on the key (anyone have a picutre of the comfort key by the way) ?
