Ahhh - its summer again.
Since the Beetle doesn't have a temp gauge I'm looking at either fitting a one or some sort of monitor so I can tell how hard its being pushed cooling-wise on hot days. I'd rather have the option of turning off A/C etc and sweating it out if things are getting too hot than not knowing until too late and cooking the engine.

On a couple of my older vehicles I've got Engine Watchdog TM2 monitors ENGINE WATCHDOG TM2, Engine Temperature Sensor and Low Coolant Alarm
I mainly like the settable alarm and am OK with just knowing how much hotter than normal the engine is (rather than needing to know exact coolant temp). Also like them being non-invasive and therefore no extra connections to leak etc.

With the Beetle being a lot more modern, I'm guessing the ECU already knows what temp the engine is. Is there a simple/cheap way to tap into that and display it - perhaps with some aftermarket bit of gear etc? Its the 1.6 petrol engine if that makes a difference.
