Why's my Audi A5 parking sensors not working?

A bad mmi fuse causes the parking sensors to stop working in the AudiA5. In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.But should You drive a car without a fuse Absolutely not. Vibrations would cause electrical arcing between fuse leads and its holder terminals. This would result in higher current flow through the fuse resulting in fuse blowout. So make sure all of Your fuses are working as they should!
