Hi,
My Audi a4 1.9tdi 2000w is not playing ball recently, the alarm does not arm,
i have the usual test to set it off, but to no avail.

I have to locate the alarm horn (to check it out) in the back but cannot find it.

Can anyone advise/help please, thanks in advance.

 

Assume you're across the pond so this may not help, but my alarm horn is in the back, on the driver's side opposite the central locking pump. Pull away the carpeting in your trunk and you should be able to find it back there.

 

Yep, i am across the pond in th UK, and my car is Audi A4 saloon.
Will have a look at w/e
Cheers
