C205 (2017 Coupe) - Alarm horn goes off when I switching the heating fans on
Hi all, my car has recently developed a weird issue where if I switch the fans on e.g (demist windows, etc) a horn goes off every 20 - 30 seconds, the reason I say alarm horn is because this particular horn, sounds different from when I lock the car, and also when I press the actual horn. I know I'll need to do a diagnostic, just trying to see if anyone has seen this issue before and if it was resolved.
