Hi All,
My 993 C4 has developed an interesting issue since we've had mad rain here in London.
I the alarm horn goes off whilst driving down the road, it is constant rather than beeping. Also I have noticed that the interior lights decided to start flashing - This is nice and in keeping with the festive season.
Also the door locks are glowing red, not flashing in keeping with the alarm being activated.
I think that perhaps water has got in to a wiring system and it's shorting somewhere.
Will this disappear once the car dries out? Is this an alternator problem ?
The most important thing is this going to cost me lost of my hard earned cash to sort out?
Cheers
Sunil

I have seen / heard this before a few times and had something similar to this happen to me. Form what I was told, low battery power and faulty alternator can cause this. don't quote me on that tho as this was like 5-6 years ago for me.

Hi,
I would not be surprised by the low battery power as the car only get driven on the weekends.
I think I'll hook up the car to a trickle charger and see what happens.

Forkin' immobilizer!!! I had an issue with mine once and it would drive around with the alarm blaring, lights flashing, etc. It fixed itself and no similar problem since. Mine didn't have any battery or alternator problems.

It is incredibly loud, you should be able to find it. ![Wink](https://rennlist.com/forums/images/smilies/wink.gif)
It's under the car, toward the back.
Hope Bill doesn't mind my posting this pic he just posted in another thread, but the horn can just barely be seen at the top left of this pic, by the heater tube:

Hi,
Actually I don't think it's anything sinister after all. I think it's just the fact that the battery was really drained. I only drive the car on the weekends and last night the alarm went off as the battery died.
Can you circle the horn as I am too stupid to find it on the picture.
Cheers
