Hi, all you.
I?m user from a ?98 Disco 300TDI in Argentina. As you may know, diesels are more problematic in case of overheating.
The experience of some users is that temp gauge was not useful to give a warning.
So I developed a small circuit board that turns on "Check engine" light at instrument panel, and a buzzer. This PCB makes warning at low oil pressure and low refrigerant level, too.
Now my question is: only Land Rovers don?t have such type of warnings, or only a small number of cars include a complete warning system? (I refer me to models older than 2000) .

Greetings
