I'm trying to fix a longggggg overdue parasitic draw with my 07 type-s. Disconnected HFL + XM unit but something is still killing the battery. The circuit in fuse #7 (backup acc) seems to be the problem.
But readings from a dtc scanner show B1225 (An open in the in-car temperature sensor circuit). From what I can see in the schematics there is nothing that shows an temp sensor... I have not touched the MICU unit (05-029)

Anyone know the location of the in-car temp sensor? And is it part of fuse #7's circuit?

This thread may help alittle as it gives a diagram of the HVAC.

I want the say the sensor is located below the key towards the footwell area.

I believe the part thats circled in the pic is the in car temp sensor.

Thank you. Found it and saw that it was in place but disconnected. I reconnected it and lets see if that was giving me the problem.
But I am doubting it. I don't know too much about electricals but how would a disconnected component give me a short unless that wire was somehow not grounded properly. I don't have my multi meter on me test at the moment so waiting to see if it kills my battery...
