These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

As title suggests really. Twice int he past week my alarm has gone off for no reason, 2am this morning and it's bloody loud! Need to get it sorted. Any advice on where to start I'm terrible with vehicle electrics, in fact electrics in general. Any help duly appreciated

POST 2Original post

Does the system set properly and do you have a Durametric?.

POST 3 / ORIGINAL POSTEROriginal post

Seems to yes. Locks and get a small beep about a second later to confirm - I presume they all do this, I'm sure my C4S did. Also I can open close windows and sunroof from the fob with no issues. Unfortunately no, don;t have a durametric - if I did would this show an error code leading me to the source of the issue? Thanks for your help

POST 4Original post

Hi Jon, Hope you're still enjoying the car despite the current prob....! What is condition of battery? Do you keep it on maintenance charger when not using it? Mine went flat once, windows dropped, spoiler raised, alarm went off.... not ideal if you were parked in an open space & it rained..... If you have had any of the above 'symptoms' could be a voltage drop & alarm senses the detection!! hth Paul

POST 5Original post

As Paul says, first thing to do is check the battery voltage. Failing that, it is most likely to be the interior monitoring sensor, or possibly the tilt sensor. A diagnostic check would show what is wrong, as it records faults, and the alarm events, and would tell you what set it off.

POST 6 / ORIGINAL POSTEROriginal post

Car is driven everyday with no other signs of battery but will get that checked out first before a diagnostic - cheers for the info PS - Yep still loving the car, by far the best car in terms of driving that I have had, every journey is fun and still not bored of the speed!!!!

POST 7Original post

Jon, I only get a beep if something is not closed properly or I 'double' click the fob to turn off internal movement sensor! Regards Paul

POST 8Original post

Aftermarket satnav. The installer probably grounded the earth wire, instead of isolating it.

POST 9 / ORIGINAL POSTEROriginal post

Cheers Paul that's interesting. Do you guys think this beep is indicating an issue on lock that could be causing my alarm to play up?

POST 10Original post

A single beep is not a system fault condition. It is caused by an open compartment, lid, door, radio contact, etc. if it were a double-beep, that would be an indication of a system fault. Did it start happening immediately after your Sony system was fitted? Edit: the beep won't be anything to do with the false alarms.

POST 11 / ORIGINAL POSTEROriginal post

Always behaved this way, and I am 90% sure my C4S did?!?!?!

POST 12Original post

Single-Locking and unlocking should be silent. I would get a diagnostic check done.
