On my 06 A8, I pulled my bumper cover off for the very first time on one of these but took some time for me to figure out and I checked the parking sensors for the parking aid and there are no broken wires or bad sensors. The only code I got is this,

01625 - Front Parking Aid Warning Chime (H22)
009 - Open or Short to Ground
Freeze Frame:
Fault Status: 01101001
Fault Priority: 3
Fault Frequency: 1
Reset counter: 39
Mileage: 121743 km
Time Indication: 0
Date: 2012.03.23
Time: 11:59:57

I'm 80% sure the front speaker/chime is bad because I clear it and keeps coming right back and I csn only get sound from the rear. Where is this little parktronic speaker located?? Ok thank you in advance.
