Damn it where's 7th gear when you need it?!
I'd say its not your battery as well if you can hear something from the starter motor! So does the engine turn over at all when you turn the key or nothing at all? Do you have vagcom to scan for fault codes? This will lead to any electrical faults that might be the cause. Is it tiptronic or multitronic? I know for instance the multitronic has a seperate ECU which is know to go up the spout sometimes, so you could be locked in gear effectively seizing the engine. You cant push start an auto so dont try that by the way!
