Alarm Problems

[Nickdaw]

my alarm has just started to go off at night for no reason that I can see. It’s the factory fit one from new. How does the interior sensors work, all is okay if I push the button on the door puller. Just wondering if any one else has had any problems.
Thanks

Mine started doing the same a few nights ago. Cant see any reason for it, never happened before

Snap I wonder if it’s anything to do with the heat? I’ve had no trouble for 2 .5 years

Will do

depending on the factory alarm its either:

volt drop/lift & tilt/doors & bonnet pin switches/interior ultrasonic s that will trigger the alarm.

the b-pillar switch disables the ultrasonics. for that key cycle.

if you have access to any diagnostics kit the last 5-10 alarm activation's are logged in the BCM for "false alarm diagnostics"

ie VCDS/Autel/Verus-D10


as @Pauly says above check for critters, make sure all the doors & windows are fully closed and check that all the door locks are functioning properly.

this is where the ultrasonic sensors are >

Thanks will have a look when I get home

Few people locally have had moths setting off car alarms.

My new t6 kombi alarm has been going off it’s driving me crazy. Where is the siren located so I can rip it out!!!!

 

[Dellmassive]

Have you tried pressing the ultrasonic disable button on the a-pillar to see if its these that are setting it off.

Also alarm events are logged if you have VCDS?

Or you can call out VW ASSIST to do a scan.

Or book it into VW for a diag


Welcome to T6F by the way.

Hi thank you for the welcome
The b pillar button works ok but is of little use - as when the children get something from the van they obviously don’t use the b button Anyway what a stupid place to put the button and what a stupid idea altogether. VW should at least provide a button on the key with the £40,000 lump of noise!!!
I wonder if I can get the alarm removed or permanently disabled.
Great idea - vw assist - I will call them tomorow for a scan and see if they have any ideas.
Thanks again for that idea

As @Dellmassive says VCDS it out.

Lol..... oops.

If its ultrasonic related, you can put a bit of tape over the sensors to disable them until you get the problem fixed.

Double press the lock button on the fob.

@Cliffspost, Or you could just double press the “lock” button on the remote, if that’s not too much trouble

 

[Salty Spuds]

Double press the lock button on the fob.

Oops, crossed in the post

 

[Tourershine]

What does double pressing the lock button do? (just to save me getting out of bed to look)

 

[Loz]

It has evolved and there was a whole topic on this but, it disables the volumetrics, jacking sensor and deadlocks the same as pressing the b pillar button.

A good reason to fix the alarm, because the temporary workaround leaves the van without deadlocking. (apart from taping over the sensors)

Personally I would empty a can of fly spray in there to start with.
