Thermo Time Switch

I'm trying to find a new Thermo Time Switch, p/n 043906163a.

I've tried all the usual suspects with no joy.

Is there an alternative part, its the one with a brown plug 14mm thread and operates 38degrees for 8secs
Mine currently only fires for 1sec

Bosch Part # 0280130214

try in the parts wanted section or see if someone is breaking an engine, thats where I found mine.
