Hi mate...

Firstly I'm better with ISTA on this than INPA, but when I was playing around with it I made a similar mistake. I didn't read the explanation CLOSELY and got incorrect errors.

The software needs to generate offset values as all cars and components are different, or put another way, because it's measuring voltages in the ride height sensors it needs to know which voltage measurement is the correct one so it can raise or lower to the right point.

It then applies an offset value to get it there.

Read the calculation sentence again and follow it precisely. From memory it is the other way around to your calcs..... actual height (your measurements) minus the nominal height (INPA)
