That beeper is behind the in dash player and very difficult to reach. You need to pull the head unit out. Because of this location it sounds like a 3D sound effect and difficult to trace to put a tape on it. lol.
Al quoz has good workshop behind MOE, drive around and see which one you like. There are plenty there. In my advise, dont become regular with one workshop, try new mechanic every time as this way gets you better service and competitive pricing.
