BMW 120D 2015 - Auto Tuner Query

[henson12345]

Hi,

I am just about to do a 120D 2015 plate and Auto Tuner suggests that I must click the drivers seat belt in before reading over OBD. Any reason this would be? First one I've come across that asks this!

Thanks

I think it secure for ignition to stay turned on...
