Help...just bought a very nice 39000m v reg slk this weekend, but the red light on the towing/alarm switch is on all the time. Also I may have made the problem worse by holding the key fob down for a long time time expecting it to close the windows before locking the car. (mistake!) Now the alarm does not sound when the car is locked, but the flashers do not stop, even after 20mins or so......any ideas?
