E34 ice warning bong - how to stop?

[skeggysteve]

I'm asking for a friend who has recently brought an E34 525 and due to global warming the low temperature warning sound is going off all the time.

Is there any way to stop it, some sort of button press thing or do you just have to live with it?

Or where is the bong noise coming from so I/he can cut the wires!

Thanks in advance.

Thanks for the quick replies.

I don't know if it comes on once or bongs all the time.
Like I said I'm asking for a friend.

I'll pass on all usefully information.
