[Vwdiesel] IDI vs TDI injectors

[Val Christian]

Can anyone speak about servicing TDI injectors, vs. VW IDI injectors?
I was looking under the hood of my TDI wondering whether the injectors
are rebuilt and tested the same way.  All these years I havn't canabalized
a hydraulic jack yet, but perhaps I could convince myself if it would
also benefit me on the TDI. 

Has anyone serviced both types of injectors?

Thanks.
