Why is your post header “Immobilizer”? Not all us (me) know what a “a3” is. Post this for the less “hip”. I know Audi had a model A4 is this a clue? Give a description about what does or does not happen when you turn the key (normal warning light activity,cranks in “start” position,that kind of stuff) I would think the CD player/radio would come up in a “locked” configuration after battery disconnect,“safe” mode has me wondering. Tell us about security system,factory or aftermarket,with remote,does it have a “valet” mode? ---

I believe the A3 referred to is a VW but I don’t know about the fsi sport , I believe it is a Touareg, I would guess that is a European model. ---
