evening all. we have recently had a new witter removable tow bar fitted to our car for our introduction to caravaning, its an audi a4 avanti towing a bailey gt60, the problem i have is it keeps blowing relays on the indicators so they dont work on the caravan,
its now happened 3 times in total on both sides even today when i towed it for 3 miles.!!. the company who fitted it are now saying it must be a fault with the caravan, hard to believe as its only 3 years old.?. can anyone help with what i should do next or
has anyone had similar probs. many thanks
