MAP sensor nipple broke inside the manifold?

The nipple broke inside the manifold. It's an 2.2 Diesel

Yep, that is a tough one, the engine might process it, or it will get stuck inside the combustion chamber or hold a valve open. You said you have been running it, how does it run? If it's okay, I think you are safe but there is no guarantee because it might be stuck in the intake somewhere. The good news is it is plastic so you might be in luck.

No, exactly like normal, a little better because of the new MAP sensor.
Smelt burned plastic smell for like 5 minutes. I drove 2 hours today as well.

If it fell into intake and it is not there then do not worry about it, it will go through the engine and not do much harm if any as it is plastic anyhow. Just replace the map and if it has a rubber gasket replace that as well if it does not come with it. Here is the location of the sensor in case someone needs it. Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.

What another of your experts said, but maybe it's different because of the car.

Sounds like you are good to go then. Let me know if you have any other problems.

Hey, I've been driving it now from September - December 1, and haven't driven it now for December 1 to January 15, since I'm outside the country,

Do you think my worries are over or it could still be inside the manifold? Thanks

it is hard to say but since you have been driving it I would say you are okay.
