I need your help please its making my head hurt trying to solve this issue with the alarm,
I have a C3 2010 A51 Model, ive had it for nearly four years, without any issues other than the norm servicing etc.
A few months back the Wiper Arms would not return to start position and would randomly stutter and stall halfway across the windscreen, now before this occurred i could hear water swishing about behind the dashboard , upon inspection the water scuttle box had at least 2 litres of water in it! i removed the wiper motor and arms so i could clear the blockage and let it drain out, it appears that the wiper motor had been sitting in water for quite a while and so i thought this was the cause of the wiper fault issues.
Then economy mode was displayed on dashboard !!!!!
I had not used the car for a number of weeks during lockdown so,
I replaced the battery that sorted that issue out.
Alarm is now randomly going off! the alarm is sounding but indicators are not flashing and wont turn off with keyfob,
i noticed when the car was running that the red interior sensor switch was illuminated constantly,
so i checked all the sensors for bonnet , doors, boot, interior sensors, all are working fine and alarm works with indicators flashing and turns off with keyfob.
I then took out the alarm siren unit a Delphi, opened it up as i found out they have a built in battery backup and after 10 years , the battery was fully charged and seemed fine, but i ordered another siren unit off a 3 year old DS3 , fitted alarm works fine.
But!! again its doing this random going off , sometimes for eleven times in a row other times singular,
all i can think of is that water has got into the main alarm module unit , but ive looked everywhere and cant find it, took lower dash off drivers side nothing , took lower dash passenger side nothing ,
Anyone know where its located? i checked where its located on a mk1 C3 but not in the same location on a mk2 , then wiring diagram states behind drivers side dash !
- Where is it located?
