Hi
would appreciate if someone could help me identify what this is. Just noticed it this morning. It’s cold here in London. I popped my bonnet of my IS 250 to check screen wash level only to notice this white residue on the bonnet catch or lock. I am going on a long journey for the Christmas break, and am now worried about it. I thought it was a coolant leak and have checked that this is not the case. So I don’t know what it is. Thanks
