pharmoun Posted November 6, 2024 Share Posted November 6, 2024 I have had my 2013 1 Series for many months and have consulted various garages, including BMW, nevertheless no one has been able to resolve the issue of the horn ringing upon unlocking the vehicle. The horn emits two loud noises when the automobile is opened after a period of being locked. No warnings are present, and the vehicle is generally in excellent condition. Do you have any recommendations? Quote Link to comment Share on other sites More sharing options...
coolguy Posted November 6, 2024 Share Posted November 6, 2024 Requires coding implementation. It seems that someone programmed it to function in that manner; typically, they emit a sound upon locking unless there is an indication that the vehicle is not secured. Carly, BimmerCode, or BMW software diagnostics will resolve the issue. Quote Link to comment Share on other sites More sharing options...
pharmoun Posted November 6, 2024 Author Share Posted November 6, 2024 I suspected that would be the situation, although I had visited other garages where I was informed they had never encountered this problem and were unable to provide any recommendations. Thank you for the recommendation! Quote Link to comment Share on other sites More sharing options...
coolguy Posted November 6, 2024 Share Posted November 6, 2024 I just had a thought. A fault code scan may be advisable, since I am uncertain if the alarm activates upon locking the vehicle. Does the clown's nose illuminate after locking? Quote Link to comment Share on other sites More sharing options...
pharmoun Posted November 6, 2024 Author Share Posted November 6, 2024 It occurs just during the car's unlocking process. Quote Link to comment Share on other sites More sharing options...
KWILB Posted November 6, 2024 Share Posted November 6, 2024 Verify if an indicator or light has been left on. Quote Link to comment Share on other sites More sharing options...
pharmoun Posted November 6, 2024 Author Share Posted November 6, 2024 No lights or indicators are activated, and the vehicle is entirely powered off when I secure it. Quote Link to comment Share on other sites More sharing options...
