HI,

My daughter's '04 A4 turbo Quattro is doing something weird. When locked with the key or the remote, after a few seconds the car starts a high pitched PEEP PEEP PEEP for about 20 seconds. Seems to lock and alarm ok. I searched the internet and Audi forums and my local German race shop had no ideas either. Only thing I could find is that the alarm may have a separate battery and it needs replacing?

here is the sound

Any ideas?

 

My buddies older Jetta did something similar to that and we traced it to the car battery being bad. .02

 

Car battery seems to start ok but will look into that. thanks!
