beeping on start up
 

Hi i wonder if some one could help me.I have a uk 2001 petrol/lpg chrysler grand voyager.Today when i put the key into the ignition i get a beep then when i start the car i get 3 more beeps about 2 seconds after that i get another 3 beeps.It is not the normal warning chime for no seat belt/low fuel it is a actual loud beep .The car starts fine and drives fine.The malfunction indicator light stays on untill engine is started and no other warning lights are on all levels are fine.Also no codes are stored via checking with the key
Many thanks
Dave

Just a update I know why I got no replys as it wasn't the car beeping it was my lpg system
