Can anyone help or advise. I own a 2010 Zafira and have had a tow Bar fitted, by the dealer I bought the car from. Due to the proximity of the Tow Ball to to the 2 inner sensors the reversing warning buzzer beeps. I know I can turn this off but I feel there must be another way to solve this problem so that the revering sensors can be used. I can't believe I am the first to have had a Tow Bar fitted to this model. The only way I am currently solving the problem is to remove the Tow Ball when I'm not towing, but tis does mean removing and replacing quite frequently.
