It is on the passenger side right behind the washer fluid fill tube. You can follow the fuel lines (look like 1/4" black tubes, some are clear) from the injector pump to it. It is a caniser a bit bigger than a normal looking oil filter and sits between the washer bottle and the metal that forms the wheel well. It is held in by a screw type clamp about half way down the cylinder. Probably isn't the fuel filter unless there is air in the lines to the injector pump or they didn't bother to fill the fuel filter up with diesel after putting it in. There is not a fuel pump in the tank in these cars so everything is sucked up by the injector pump and it needs to be primed properly.

Fill the filter with ATF, if no diesel fuel is handy. The T section with double o rings and a hair clip was removed, pour ATF in the resultant hole until it was full. Remove the clear line from the filter to the pump by disconnecting it at the filter. With a thin tube fill the line with ATF fluid until no bubbles remained. Reconnect the clear line to the filter. The car should start immediately.

Best thing to do is a fuel pressure test, the car does not have to be running to do the test just turn on the key. You can rent the pressure tester at auto zone.

Should be mounted the same as a 2005. On the inner fender, above the right-hand wheel arch, in front of the windshield washer tank. Pull the retaining clip that secures the control valve to the top of the filter assembly. Pull up the control valve and its hoses, away from the filter. (1) To drain water out of filter: At the bottom of the fuel filter, loosen the drain plug, while holding a container underneath the filter to catch the diesel fuel and water. When you have drained the water, and diesel fuel is now draining -- stop! Twist the drain plug closed, pour a few ounces of fresh diesel fuel in the top of the filter. Use a new O-ring when reattaching the control valve to the filter top. When the vehicle is running, check for any leaks. (2) To replace the fuel filter: start where #1 above begins, disconnect the fuel control valve from the top of the filter; mark the other two fuel lines with tape and disconnect them (they may be attached with spring clamps that you will need to cut -- replace them with screw-type fasteners, see instructions below); remove the fasteners and take the filter and mounting bracket from the vehicle. Loosen the bracket and remove the filter. Fill a new filter with fresh diesel fuel (you don't want to try to turn the engine over to fill this filter -- you may burn up your starter) and install it in the bracket, then reattach the bracket to the vehicle. Attach the control valve with a new O-ring and secure the hoses with screw-type clamps. When the vehicle is running -- inspect for any leaks. Hope this helps -- these are instructions out of the 1998 - 2005 VW manual. Should be no different for the 2006.

PROCEDURE TO CHANGE FUEL FILTER
1) open the drivers side door pull the hood release.
2) lift up the hood, ideally your car has been off for a few hours so it's not too hot under tehre.
3) look to your left there's a cylander with four hoses coming in and out of it. (two in, two out)
4) pull the mickey mouse looking pin from the two hoses that are in the back. the little circular thing should pop out with a little bit of effort.
5) look inside the fuel filter, doesn't it look gross? Aren't you glad your changing it? (most of the time it's going to look gross even if it's in good shape
6) Pull the squeeze clamps back from the other two hoses (the front two)
7) carefully pull those hoses away from the fuel filter (they both will probably have a little gas in them)
8) unscrew the phillips screw to the right of the few filter and remove the fuel filter'
From here you can try just draining the water from the filter and seeing if that solves your problem or you can replace the fuel filter.
9) the most important thing is to remember to put some diesel inside the fuel filter before you start your car other wise it'll be alot more difficult to start.
10) put everything back in place and start your car.
You'll probably have a little difficulty at first , but if you just keep cranking it (don't be afraid diesels are tough!) the car should start in less then 2 minutes. Obviously use common sense here but it shouldn't be too bad.
