Can I remove a user and reset with Orbit?

[x119]

Under IHU there is a routine control "IHU Factory reset" - I've had no reason to try it; but I can't see why it wouldn't work here. 

You can definitely delete the key in Orbit. 

I'm guessing that doing this will void the warranty right ?

I can’t see how. Car doesn’t have a memory of what’s sent over DoIP. These are just diagnostic commands.
