If your Tdi auto had EDC (Electronic Diesel Control) which is likely at that age, then yes, it will need a remap rather than manually tweeking the injection pump.
The way to tell is to look and see if you have a bowden cable operated throttle pedal or a 'fly-by-wire' electronic one.
My '98 is the same, auto EDC but I found after doing several of the mods reccomended on this forum she runs loads better:
1. De-EGR
2. De-Catt downpipe
3. Regular changes of air filter.

from start to finish
remove the four screws from the power valve on top of the pump ( squarish plate with brass cover in centre ..big screwdriver very tight) The top of the plate will spring up...notice how far it rises on top of the spring.(say 7mm) Remove the cover. Then you will see a black diaphragm..if you want with tippex mark its positon relative to the casing and then remove the diaphragm (lift edges and pull up) remove the spring underneath (do not move the trottle when the diaphragm is out !!) at the bottom of the cavitly you will see a toothed wheel. You need to screw this down to reduce the lift in the top plate to about 3mm ( 7 - 4 =3 ) Wind it down with the edge of a screwdriver
Don't understand the last bit of this can any 1 help? How many clicks should I turn the wheel or how many degrees, many thanks
