I saw something similiar on a 2000 TDI Beetle and I
tested all kinds of things and after much research
ended up replacing the temp sensor on the head that's
for the controller.

But I'm not sure that it actually helped. I had a
problem with the EGR valve being all caked up.

Just something to look at. It's on the backside of the
head on the drivers side of the engine, if memory

Good luck,
