Question about 2000 Volkswagen Jetta TDI
On way to work noticed significant loss of power w/ no noticeable event preceeding. Hard to maintain 60mph on minor inclines and drop down to 50mph on moderates. Revs up to 3100rpm on moderate inclines w/ little acceleration response. Have I lost my turbo or dropped a cylinder or something like that?
Not mechanically inclined.
If all checks out good on the turbo, could be Cat. Converter. Does the car have a lot of miles? Are you getting a Code"engine light"? if so, take to an auto parts place to read code, should do it for free.

Major loss of power suddenly is probably limp mode. This is a very common issue with high mileage TDIs. The ECU will pull boost to "protect" the engine from what it thinks is a potentially damaging situation. The most common cause for this is degraded vacuum lines, a faulty N75 valve, or stuck VNT turbo actuator.
Since this happened suddenly, I'd suspect vacuum lines or N75 valve. Stuck actuator is usually progressive and not sudden. Secondly, if it is limp mode, you should have a check engine light. The codes that will reveal can help pinpoint the issue.
I'm not going to tell you this will be cheap and easy to fix, but it really is a minor issue. If you're not mechanically inclined, it's time to get this to a trusted TDI mechanic in your area. Check out this google doc to find a mechanic close to you:
