Just got an IID Tool and have been looking through seeing what is and isn't activated.
In the Car Config / Confirmed List / IPC Instrument Pack it states Towball not fitted.
Car has a Towbar and everything on the Tintent works and I get the Green Trailer Symbol lights up on the dash when plugged in.
Tempered to change the setting to Towball fitted but not sure what effect this would have.
Any advice ?

Does your rear fog & parking sensors disable when towing ?

Some potential clues on this thread about what the CCF setting might actually do.

Not checked this but will at the Weekend. Just playing at the moment and looking for info before taking the plunge and changing things.
Did find that thread on a search but wasn't any wiser after reading it.
Think I need to read it again
