300 tdi low coolant alarm

I'm wondering if anyone has any up to date information on how to go about this . All the threads I've read have been a good few years old.

Is it still the case of a Range Rover expansion cap with a custom circuit ?

If so now that these circuits have been out there a while , which has worked best .

Thanks in advance

Get the Madman. Lots of extra info like egt, txbox oil temp, oil press, water temp (almost realtime) & of course coolant level.
It already saved my engine with the coolant level warning.

I bought a low coolant alarm from Ebay for £ 25, it has a visual (led) and audible (buzzer) alarm, and a test button. I modified the reservoir cap to accept two copper rods to act as a sensor. Works perfect.
