Provided you have the ALH engine, the thread in the link above is the definitive guide for troubleshooting power/driveability issues with your TDI. If not, it should still provide some good information for future troubleshooting.
Hint: start by replacing air filter and all vacuum lines, then remove and clean intercooler (if more than 150mL of oil, inspect turbo shaft bushings and seals), then clean intake manifold and intake ports, then disassemble/clean VNT turbo actuator and vanes. And of course, pull codes with VAG-Com.
