horn going off when lock car

**mate** · 24th March 2015, 03:44 PM

hey guys

is my horn supposed to go beep when i lock the car after having the bonnet open?

or is there something wrong with my alarm?

Alarm beeps because bonnet is not shut properly, or a least the limit switch which tells the alarm the bonnet is closed is faulty.

oh ok so if the switch is faulty how is it knowing the bonnet was opened in the first place?

Mate,
The same happens with my D2a, if I lock the car using the remote key fairly soon after closing the bonnet (or if any door is not properly closed).
However, it seems to me that if you wait longer (don't know how long, but say, 15 minutes or more after closing the bonnet) before locking, the alarm does not sound a beep.
Try it and see what happens for you.
Cheers,
Andrew

My L322 does that due faulty bonnet switch bracket. I pulled the plug on the switch. I found the bracket holding the switch had some wear allowing the switch to move a little.

Hi rar110,
Did you manage to make any modification to the switch bracket, such that the alarm now does not sound when you close the bonnet and then lock up?

After you close the bonnet, open and close a door and you may also find the horn then does not beep when you lock the doors.

Not yet. The plan is to cut some thin alloy sheet the same shape as the top of the bracket and sicaflex that to the bracket. The model after mine has a steel bracket so it must have been identified as a weakness.
