As title really. INPA works OK, at last; I can read fault codes for various modules, it shows the real-time brake and clutch switches yadda yadda.
However, the "ignition" circle is black when connected and turns white when the ignition is switched on, the opposite to the expected behaviour. Is there any reason for this?
Also, how do you get it to dump all faults in the memory? I saw this done by my friend (who works for BMW) but I can't find the option. In particular he found some alarm faults last month, which we cleared, and I'd like to see if they ever reappeared. I can't see the alarm module in the menu although the immobiliser module has no faults stored. This is a fairly minor thing since I rarely lock the car at night - it lives in the garage
There was only one fault I found by going through the various modules; the duff PDC sensor, but that is now replaced so I cleared it.
