I have a 98 (S) 156 V6 which has working central locking but does not appear to have an alarm???

Is this likely, or is it more likely that someone has disconnected it in the past, I expected to find that when I use the remote central locking the indicators would light up to confirm locking/unlocking but all that happens is the car unlocks.

Any ideas/advice welcome.

Cheers

ALL UK spec 156 came with a factory fit alarm as std

The lack of flashing indicators doesn't mean there is no alarm.


Lock the doors with the remote, then open the door using the key in the lock (NOT the remote), then with will find out if there is a working alarm.

Is there a red LED on the panel that also has the central vent on top of the dashboard?

Could be the alarm has failed and/or it's been disconnected. It's inside the front n/s wing, so the plastic inner wing shield has to come out to get to it.

If you have a friendly local Alfa/Fiat specialist they can check the alarm by connecting the car to the Examiner diag system.

I took the n/s wheel and inner wing shield off to get to the alarm, found this a bit of a pig to do, but then my abilities are limited!!!!

For some reason the alarm had been disconnected?????

I have reattached the connector and after two days, so far it seems to be working fine. I am just waiting to find out why it had been disconected, I will probably find out that it goes off erratically!!!!

Thanks for the advice guys :thumbs:

It's surprising what you can do if you try ...

It's either an erratic problem, which means you and the neighbours are most likely to find out on a cold wet night in December around 3am! ;) or the fault drains the battery. Either way, unless you check youll never know. Or it's unrelated to the alarm unit and could be the internal sensors or something. Some people don't check things thoroughly and go for the first thing they can think of. :(
