It is upto normal operating temperature now unlike the previous photo..
Wonder if being a manual makes a difference..set a slower idle?
TIS says "Idle speed control
For idle speed control, the Digital Engine Electronics (DME) control the following factors:
Air mass (via Valvetronic and electrical throttle-valve actuator)
Injected fuel quantity
Point of ignition.
The set engine speed when idling depends on different conditions, for example coolant temperature or power requirement of the auxiliary components."
I assume no error codes when you looked?
