Activated "Trim Line Mode" help please.

[Shane2jz]

I have kept noticing recently that when parked on level ground that my E53 looks a little lower on the left rear.

Last year I had some hassle with rear sensors and replaced them and never looked into calibration, something I read needed to be done. So had some spare time today and ran INPA to see what was possible in terms of setting up the level. Instead of that I have activated "trim line mode" and I am unable to unactivate it now.

What is Trim line mode? I have googled it and mainly comes up with links to "Transport mode", I have seen this ans in the same sub menu as trim line mode. Currently I have Trim line mode showing a black dot and Transport mode showing a white spot, so ppresumably only trim line mode is active at present.

I was thinking like most other functions in INPA it would be a toggle of the same F key but seems not. Telling me to wait at least an hour, do I need to wait ans try to disable it again? Any help apreciated, thanks.
