When, a car has a bad battery, charging issue or hasn't been running for awhile, you can have a couple of issues, a non start being one of them. It is possible, that the immobilizer; is kicking on or the throttle body alignment settings, have been lost. You might try a hard reset of the ecu; as low voltage, can "confuse" the ecu and cause, the immobilizer to kick on. Hard Reset: remove the the positive and negative battery terminals; touch them together, for a number of seconds and reinstall. Also, a throttle body alignment procedure; might be needed, to get things back to normal, working alignment settings.

Beyond that, a scan for trouble codes (preferably with a vw specific scan tool; like VCDS by Ross Tech); might be a way, to rule out any specific trouble codes, that might give you a clue as to possible other issues (immobilizer problems; typically, throw a vw specific trouble code).

Basics, such as: ignition spark, fuel pressure and compression, shouldn't be overlooked. Another common problem, is old gasoline (benzine, petrol, etc); can lose its normal combustibility and cause a no start issue. Using some start fluid; sprayed into the the intake hose off of the airbox, can be a quick way, to rule that out. If it start and runs fine; while squirting combustable fluid into the engine (starter fluid, carb/intake cleaner, etc), then poor fuel pressure or bad fuel, could be a issue.
