Am I correct that the MAP sensor for a 2001 Passat TDI 130 is the sensor in the plastic inlet pipe at the back of the engine, held in by 2 screws and connected with a 4-pin plug?

I ordered a replacement from the local dealer and they've given me a plastic housing that fits into the inlet tract and has the MAP sensor built in. They also say I have to return the old version (exchange).

I want t be sure before taking it back and telling them it's the wrong one.
