Question moved to category.

It could be many things. Does the engine turn over, but doesn't fire? A flat battery is the obvious one. There is help and videos in the link.

ask your mechanic

May be unrelated, but could well be a vacuum hose was damaged or knocked loose. Check for loose gas cap too. Use a lenght of hose one end in your ear, other to poke around in engine bay to listen for vacuum leak. CAUTION don't stick hose in fan or other moving parts!

Runs good most of the time? Doesit matter how full the gas tank is? If the power is low how long doesit stay low? a second or two. or even less? when the power comes back on is it as good as ever? Are you talking about driving power or electrical power? the electrical power is made by the altenator and the pulley has a clutch that can go bad and the charge comes and goes. a good shop can change just the clutch. A bad battery can make the altenator clutch out so it doesn't fail charging a battery that won't charge. get the battery tested. Most auto prts stores can test the battery in the car for no charge. Engine power can be check engine light related, Is the check engine light on? Exhaust pipe bent closed or stopped up? oil change up to date? The oil can break down and sludge, when it does the engine starves for oil and partly seizzes. Low oil level can do it too. VW's are bad about sludging the oil does it more if the oil is'nt changed often enough.

dealer to reset trans control module

On the 2007 vw beetle there is an unlock screw that you have to turn a quarter of a turn to unlock the light assembly by using a 5 mm. socket.You also have to push down on the silver release bar and pull the light housing out at the same time.The bar is 3 in. away from the unlock screw,towards the fire wall.

Look in owners manual you can do this yourself very easily using ignition,milage reset button and clock reset button it's in the book cant remember which page

This is common problem with many vw's
Sounds silly but change the brake light switch under brake pedal.
Often solves the problem (about £8 for switch) will need the light turning out by diagnostic tool.
