e430 frnt parktronic dead
 

The front parktronic dispaly is showing no life whatsoever.

Using carsoft i saw the front sensors all reacting - so they are OK.

Can someone help me with the working sysytem -s pecifically,

what enables the or disables the system i.e. as afar as I am aware it uses the front left abs related wheel speed sensor - so as i do not have an ABS fault that is surely OK.

I get absolutely no display 9have tried a second hand unit as well.

Is it possible the unit has been disabled from displaying and or does one have to programme in the replacement of the front dashboard display?

Once again - seen the sensors pickinp and displaying distance but no lights on dashboard front display - even at start-up,

any help in how to diagnose greatly received
