Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Reported cause

After lots of research I determined it was the alarm module which was buried in one of the wheel arches.

Couldn't get a new siren unit, so they removed it, replaced the tilt sensor, so the alarm sounds via the horn now.

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

Hi all, I had trouble with my alarm after hand washing the car, the alarm went into a mind of its own and kept going off constantly, but could start and drive it with the alarm going off. Car went into Indy, they said battery in the siren was old and low, and that the tilt sensor was corroded. Couldn't get a new siren unit, so they removed it, replaced the tilt sensor, so the alarm sounds via the horn now. £800 later. However, picked the car up and the alarm is still going off randomly, it stops with the key fob, which it didnt do before, but to stop annoying neighbours ive disconnected the horn. Any ideas or recommendations to look at?

POST 2Original post

I had a similar problem with another of my cars, a 2007 Audi TT. After lots of research I determined it was the alarm module which was buried in one of the wheel arches. Anyway, long story short, when I went to order the part number from a company called LLL Parts in Europe, a message came up to say exactly the same part was available for Skoda & Porsche, with the former costing less money than the Audi version and the latter more. So I took a risk about bought the Skoda version. It fitted perfectly and the intermittent random alarm stopped. So might be worth a look - the Skoda part number was 1K0951605C

POST 3Original post

Is there any dampness under the passenger seat? That's where the alarm control unit is located, at the lowest point of the floor. A blocked drain can cause water to spill over into the car, and it collects at this point. Other than that, get a proper diagnostic check done. Someone who knows what they are doing will be able to read the last 10 events that caused the alarm to go off. Also, did the indy code the tilt sensor out of the system? Is the car battery in good health? Low voltage will cause all sorts of electrical gremlins, and the alarm system is often the first to start playing up.

This is a source reference. Confirm exact model applicability in the original material.
