OK. This is the solution. Get rid of the feature by disconnecting the wee wire on the battery.
Simples. I did it v shortly after getting my 7.5. Never looked back.
Ooohh.... I didn't know this was possible..? I haven't looked at the battery, is it obvious which wire to disconnect..? Does it throw up any fault lights etc or affect anything else...?
There is a thin wire connected to the side of the battery. Just slide it out of the tiny socket and tape up the wire and socket to protect from damp. This is a “ battery condition” connection which also works the S/S.
From time to time you will briefly get a “ stop start disabled” message on your digital dash. It appears randomly and disappears v quickly.
There is no downside to doing this cost free improvement. Don’t like it any more? Just reconnect the thin wire. Apart from unplugging the Soundaktor, it’s the best, and cheapest, thing I have done to the car.

Let me know how you get on.....
