I have an E36 96 328is coupe... and it has an alarm.. However most tell me the car should beep twice when locking.. and once when opening.. HOWEVER.. mine has.. and has always.. (been over a year now).. beeped 4 times when arming.. and once when opening..
BEEP BEEP BEEP BEEP... on arm.. no change in tone or speed... indicators light up with the beeps...
BEEP.. same as the arm one.. but only once.. indicators light up with the beeps...
My alarm fob says... Sigma AC38
Is it working correctly?
