Hi
I am a new owner of used Audi A4 Avant 1.9 tdi 2004 year. I was searching for anti theft alarm and immobilazer for my car, but I can not find any!The car does not make a horn sound when I lock him and I try to recode the adress 46 cent. conv. to add 1024 (to make a horn) to my code (06976-code of add. 46) without success! I make also a output test of same modul but there wasn't any option for alarm horn or test, only some locking and unlocking options. Then I was wandering about immobilazer and I couldn't find a sign on instrument cluster. I looked on owner's manual (which is in german- I do not understand a word!) and I recognized the symbol but on the plase of this symbol in my cluster is another symbol which I do not know what is it! I am sending a 2 pict of my cluster and I circled it.
Please help if somebody know what is the meaning of the symbol,is it a immobilazer?

 

i think that might mean low air pressure in one of your tires

 

isnt that for traction control. At least thats what it is on mine when it flashes or u turn off ur traction control that symbol pops up

 

oh and for the immboliZer see if its in your door panel maybe. drivers side where that cubby thing is. I dont know cuz i never seen the inside of an avant

 

Yea, that's exactly what that is. My boss's toyota has that exact symbol, which is for your tire pressure.

 

That's the low tire pressure warning. think of it as the cross section of a tire ballooning out at the bottom.
