i have a 1997 c 200 and when the fob is pressed to lock the doors the hazards continue to flash this fault is intermitent the siren does not go off just hazards
any ideas
regards cyril

 

sounds more like a faulty sieran you have....

 

no you missunderstsand naz if you activate the alarm by leaving the windows open and putting your hand in the siren sound and the hazards flash,
but when you just want to lock the car with the fob,it locks the doors and the hazards flash a couple of times like it should do,then for no reason the hazards start to flash very fast but the siren does not sound, and they will continue to flash until you open the car with the fob,
also when the fault is present if you get out of the car and dont lock it after a few seconds it locks its self and the hazards start to flash again

ok lets do some checks.do you have a flip key as in when press the botton the key flips open if do have,for a start change the batterys in the key fob,after change of battery slot key in to ignition on positionpess lock button on the key for 6 seconds then switch off lock car and un lock see the results let me no hw u get on

 

thanks for reply naz
no its not a flip key,its the triangle shape,but i have noticed because its been dry the last couple of days it hasnt done it so i am wondering if its water ingress in the siren because i believe it sort of controls everything so i am going to look at that, i believe its under the n/s/f wing ??

yes very common if it as any water on the siren it does play up and the sirens are not cheap, ithink they about £80.00pls
