Mk5 VW Jetta, Sportwagen, and Audi A3 TDI forum
I can find videos for the golf that have the big black box (with a battery that goes bad) inside the right fender, but not for this car.
I think the right siren is 5c0951115.
It looks like just a horn, no battery or anything thats likely to go bad, but mine's not working.
All my doors lock...
