A used OEM Audi battery positive fuse, factory part number 4B3937505A, also replaces 4B3937505 and 4B3937505C. This fuse connects the battery to the main electrical system; when it fails, the car may lose all power or exhibit no-start symptoms. Removed from a donor vehicle, it’s a direct replacement for Audi models equipped with 2.7L turbo, 2.8L, 4.2L NA, or 4.2L turbo V6/V8 engines.
