I had my head off recently for head gasket replacement and took all the injectors off. There is a special copper washer under the injectors. Not sure how easy they would be to get out. I do know that they are concave and have to go in a certain way.
Don't panic about injectors!
DO get new bottom sealing washers of exactly the right sort. Just dig the old washers out and clean out the recesses absolutely free of dirt or oil.
Old washers CAN be restored by annealing. Heat RED HOT and dunk in ice-cold water. Do this twice to each injector. This SOFTENS copper.
VERY GENTLY side the washer up a fine sharp DEAD FLAT file twice each side turning 90° between slides. This takes the shine off the washers.
Refit with coppergrease lightly applied to all the bits copper washer and all. Torque down as Landy recommends. Check torque regularly (daily) for a week.
Find someone with a Hartridge injector tester (I have one!) and get the injectors tested for pressures, spray patterns and leakoff.
At such a low mileage they should be perfect, and good for half a million miles more.

I got mine from bearmach for my 200tdi along with the 8 washers for the leakoff pipes.injector seat washer x4 part no ERR4621 - £0.20 each and leakoff washer part number x8 part no ERR1304 - £0.22 each.not sure if the washers are the same on the 200 and 300tdi's.Also not the end of the world even if you've got to get them from the dealers at that price.
Do not replace injectors, just have new nozzles fitted and calibrated, the workshop reconing the injectors will have the washers. Also worth replacing as mentioned earlier the 8 little washers on the leak off tubes and for what it costs the tubes as well (just buy a couple of foot of pipe).
