That's EOBD, and I'd also like to know what that means for diesel engines...
The joke is, while my Euro 3 ALH engine doesn't have a readiness code, it does support EOBD.
I can then display the throttle valve angle... and see the accelerator pedal potentiometer

.
There's also a calculated value for engine load, expressed as a percentage. What exactly is being displayed for that value on the VP-TDI?
Is the voltage applied by the control slider somehow scaled as a percentage?
PS: Air mass in g/s can also be quite interesting; it gives you a completely different "feeling".
