Can VW change/remove the bong when the outside temp (OST) drops below 4dec C. As it is driving me potty. Picture this, driving enthusiastically and then all of a sudden hear this bong. "Whats that!" I wonder. I slow down and look at the dash, and see the OST has dropped to 4 dec c. Do I really need to be told. Sorry I digress. So is it possible to either remove the bong or have it set at 0 dec c?
