If you are not leaking fuel, then you can drive it without any detrimental effects at all. As others pointed out, it is the fuel moisture sensor, but it also doubles as a bleed valve, to get rid of any detritus or water stored in the fuel filter. I bleed mine the first weekend of each month - good habit to get into. One thing about those sensors - you don't know if they are not working until it's too late.

You also need to remove this when you change the fuel filter. Drain out the excess fuel and dispose of properly - don’t put it back in your tank. Also, don’t attempt to unscrew the sensor fully, until you unclip the sensor from the sensor wire, as you will not have enough play in the wire to accommodate the number of turns necessary to get it off.

When you change the sensor, follow usual safety precaution for working with fuel, and make sure the keys are not in the ignition, especially if you have electronic fuel injection (like on the TD5) - these self prime, and if that valve is off - they will keep trying to self prime, and you will wonder how much fuel fits into that little filter ;-)

The thread on them is also pretty fragile and will break if they are overtightened. This will lead to leaks and the possibility of losing all your fuel, I would replace it or keep a bolt with the same thread to plug it with prior to a big trip.
