Looking around in the engine bay of our '11 Countryman All4 I noticed a couple of things have been unplugged (prior to our ownership).

First is what looks to maybe be a vacuum hose coming off of the sensor on one of the hoses coming off of the airbox. I have two questions regarding this. What is the sensor called, and where does the other end of the line go?

The other is what I assume is the coolant temperature sensor. Does anyone know where the connector for this should be, or have a wiring routing diagram so I can narrow down where the connector branches off from the main harness?

Any and all help would be appreciated!

First thing is a blind plug, not used.
Second thing is probably the result of a retrofit as I recall. Not 100% on this, a search will find it.

Well, back to the drawing board then. Was hoping either of these may solve other issues.

Thanks though.

Blink plug and conversion for the updated thermostat, so they dont use the old plug and someone put a bunch of sealant on the hold sensor housing so it would not leak.
