We talked about this before, but I now have a picture to make my question more clear. Any Bosch experts out there??

I removed my '98 E320 MAF sensor - There are apparently three parts to it other than the internal electronics. These are:

- External electronic part mounted on a u-shaped wire - Is this the thermistor for temperature measurement?

- Flow through cavity with shiny plate inside - Is this the hot film? There is also a drain hole on side.

- Dead-ended cavity near bottom - hard to tell, but there appears to be two wires one behind the other - perhaps connected to hot film? What is this for?????
