Hello brains trust.
Having bought a car manufactured this century (2001 scenic rx4), I find myself without any engine diagnostics and will probably find in time such a device is needed.
I'm hoping it wont be, but bugger me if I'm going to pay someone else a stack of money to do a simple diagnostic so I'm asking if anyone here has any good ideas about what units are good and what units are to be avoided.
I've become accustomed to having real time monitoring of sensors on the 80/90's renaults with the XR25s, and on my fuego with its built in PC, so a basic fault code reader will probably not be what I'm after.
Any suggestions or advice???
