u mean off engine dee then the number of seconds still keep fluctuating ah?
if thts the case i think your timer sot dee lo...coz even if its auto mode,once u turn off the ignition key n take your keys out,the number displayed on the timer will start counting down mah,after u take out the keys dee no way the number can go up somemore one,it will definitely count down
if the number goes up n down like fluctuating after u've taken out the keys,i think something wrong with the timer lo
under warranty then go claim warranty lo
otherwise ask if any of retailers like KSP or N1 got provide serivces to send back for repair lo
hope this helps :)
