2003 Jetta TDI vibrates above 35 speed
With 180k I would change the engine mounts. They are about the only thing that would dampen engine vibration and noise (assuming that the engine is running ok). There is likely one or all weak or broken. Normally when you have a vibration at speed then it is going to be driveline or wheel balance.

There is no throttle body on a TDI, but continuing to crank you engine with no fuel pressure will absolutely fry your pump and/or injectors (An '03 could be either an ALH or a PD engine, - different fuel injection systems, but same disastrous result in either).
Here's my .02:
DO NOT let a VW dealer touch your TDI. They commonly throw parts at it until the problem either goes away or they throw up their hands and say "I dunno". Either way, people routinely waste a boatload of time and money with no relief when taking their TDI to a VW dealer.
Go to TDIClub.com and look for a trusted TDI Guru near you (there's a list by state) and have one of these guys look at it. They're very helpful and more knowledgeable than 95% of VW dealers.
Good luck.
2003 VW jetta speedometer stopped working and the
The speed sensor that is under the trans. mount on the driver side sends the shift points to the computer telling it at what point to shift. The sensor that actually controls your speedometer is in the back near the firewall. It is tall and should have a silver heat shield over it. However, the problem that you have described sounds more like an electrical short or a wire grounding out somewhere. I would check for wires getting pinched under the steering column in the dash since things quit working when you are turning. Also check the wiring behind the instrument cluster. Elecrical problems can sometimes be complex and hard to find but with some due diligence they can be solved. Hope this helps.
