Hi, I am a new member to Audi and have recently purchased an A4 Avant 2.5Tdi. The horn does not sound right but cannot find it. Please can you help me locate it. I know it is at the front of the car. I also know you press the centre of the steering wheel. This may have been a topic before and I am sure someone will have the answer. Please accept my appolgies for going over old ground. Many thanks.
