Changing my 5th gear to a higher ratio for increased fuel

I recently changed the nozzles on my 02 and lost 4mpg.  Instead of changing the nozzle back because, I don't have them, I was wondering if I could just change my 5th gear?  I was wondering if anyone has any info on this either way????  thanks buck

 

Coolant Temp Sensor

My temp gauge dropped all the way down a few times during my drive home, then eventually didn't move.  My heat was working great so I am assuming its the sensor. 

It appears this is a fairly common occurance, for me it started at 167k, not bad.

I found a great writeup at http://www.inmud.co.uk/page28.htm

For reference sake I am replicating it here with my own notes.

Tools needed to change this sensor:
A small flat blade screwdriver and 10 30 minutes of your life

Parts needed:
Temperature sensor :    VW  059919501A
Rubber o-ring:                VW  N90316802
Spring clip:                     VW  032121142
Up to 1 litre of G12 coolant plus distilled water.

You can get the parts very cheap if you do a search online rather than going to the VW main dealer.  Fairfield VW total cost was about $35 at the time of this writeup, although I already had extra coolant.
Let the engine cool for as long as you dare, you can still burn yourself after a few hours but it's up to you.
Release the pressure at the expansion bottle.  I squashed a radiator hose and resealed the cap to put the system under a small amount of vacuum

Project 44 How to Flush the Brakes On a 2003 Jetta TDI


VW recommends the brake fluid should be flushed and replenished every two (2) years or twenty-four (24) months. A technician at a dealership uses a machine to do the job in ten (10) minutes at a cost of $129.00. You don't have such a tool, but you can fight back.

Antenna Gasket Repair

Evidence of water that has stained the headliner (in back) is usually caused by a defective antenna base mounting gasket. The gasket is made from a soft material that will crack and deteriorate. This usually happens within three (3) to five (5) years of the vehicles life.
