Got this from another forum and thought it might help with some of the questions

(Note: Some features may not be available or present on all models)

1) Remote Window Closure / Opening

After leaving the car, press the 'lock' on the remote, and keep it held down (on)....the windows and sunroof will close (only whilst you hold the remote button)

Conversely, pressing the 'unlock' on the remote, and keeping it held down will open the windows (but not sunroof)
Release the remote when they are at desired position!

2) Windscreen Wiper Access

The windscreen wipers are neatly tucked away when not in use for aerodynamics and safety.

To clean under them or change the blades is easy!

With the ignition key in 'off' position or removed, pull the wiper stalk down momentarily.
The wipers will wipe to 12 o'clock position and remain in that position.

After completing your task, simply repeat the wiper stalk action and the wipers will 'park' in the usual position.

3) Fuel Flap Release

The electric fuel flap release is inhibited if travelling at over 5mph (a guess)

4) Automatic Rear Screen Wipe

With your windscreen wipers activated in any mode, selecting reverse will cause the rear screen wiper to wipe once.

5) Headlamp Washers

Headlamp washers will only wash if your headlights are switched 'on' - at the first time you wash your windscreen, and then every fifth time your wash your windscreen (resets after ingition switched off)

6) Zone Climate Control Synchronization

if you hold down the AUTO button for three seconds, it will synchronize the temperature setting on both sides of the car to match that of the drivers side. When ever the driver changes his temp setting it will also change it on the passenger side, until a passenger changes their side.

6b) Zone Climate Control Degrees C to fahrenteit

Pressing and holding the Auto and Econ Buttons at the same time will swap the temperature from oC to oF and Visa Versa

7) Passenger Door not unlocking

If you press the unlock button more than twice in quick succession the passenger door ONLY locks itself, unlocks on the fourth, locks on the fifth etc.

Its a software problem that hasnt been rectified yet but its nothing to worry about

8) Coming Home Lights

The headlights only stay on for the 30seconds or so if you have put just taken the key out of the ignition. If you dont want them to stay on when youve parked up then lock the car, unlock and lock again.

9) Regards FSI owners mainly.

The higher the octane rating of the fuel the longer the FSI engine will run in FSI mode.

You see, when the FSI is running in 'Fuel Stratified Injection' mode it creates a lot of NoX (NoX - Very bad as far as emisions go) due to it being such a lean burn, so it has a NoX Cat which abrorbs the NoX, once its full the Nox probe (fancy lambda probe) senses this and the engine switches back to normal running and can safely clear the NoX out with the other gases through the main Cat so it can switch back into in FSI mode again.

The problem with octane levels is, and this is just an example depending on driving styles.

Out of 100 miles average :-

95RON - 90 miles normal, 10 miles FSI (lots of NoX made in FSI mode)

97+RON - 60 miles normal, 40 miles FSI (some NoX made in FSI mode)

Now regardless of what anyone says this is how the engine is built and as its more efficient in FSI mode VW always recommend the highest octane rating for this reason, they did introduce a 1.4FSI for the uk market that is made to run on 95RON fuel for longer but you want to see the size of the NoX Cat, more like a tanker. lol
