I wouldn’t even bother with INPA, leave installed on laptop and download ista instead. Get a k-dcan usb lead and use ista instead just have to do some tweaking of files in edibas bin to get it working.
I have ista now that works spot on with e91 and e90 but still cannot get INPA to work.

Assume you have the instructions for setting up a connection, if not have a read of this.
Other than that I can’t offer much help as I am clueless with IT stuff,deepcdiver assisted me when I was having issues setting mine up for e series vehicles.

If ista connects ok then it should clear the air bag fault, what happens when you try to clear it?

Very odd as ista reset airbag fault on my 2010 e91 no problem, it was a self induced fault though as I unplugged some wiring. Are you sure the airbag fault is fixed and it’s not just immediately returning after codes cleared?

I do as it says then click the cancel button, ista then goes through the motions and clears code

I've replaced the airbag entirely! I had read about the bracket causing grounding issues and was careful upon installation to try to get it right, unfortunately I only read about the problem, there weren't any pictures showing the issue.

When you say do as it says then press cancel, do you mean go through the test procedure telling it you've replaced what it says and that everything is ok and it'll then go through the reset process? Because when I try to reset through the individual module it happens suspiciously quickly, like as soon as I press the button it says it has reset it. That doesn't seem like enough time to actually do it so I wonder if it isn't behaving as expected?

Battery is charged now, been for a decently long drive so I'll try the above tomorrow and see if it manages to reset the bloody light??! Thanks again for your help!

I tend to read all codes and then do clear all rather than do individual modules,takes a bit longer but seems to work fine.
When it prompts to take key out do what it asks,click cancel on the pop up that closes and behind that is a progress bar that completes. Turn ignition on again and rescan faults should be clear. Well they do on my e90 and e91 anyway.
