Help Accessing FRM module in INPA
2006 e92 and I have i think a rear levelling sensor issue causing my headlights to go into a fit .. constantly going up and down,
INPA throws code FRM 9CB4 , how can I access this module to see the real time values ?
It doesn't appear that the module is available from the menu ( searched high and low).
The reason why I would like to see real time data is because the 9CB4 error has been evident on my car for many months and only recently in the heavy rain have the lights gone mad.
Any help on how to access it would be appreciated. These sensors are around £100 so need to be sure !
