Checking and Replacing Fuses
The various electrical circuits are protected by fuses. Fuses that have blown will have metal strips that have burned through.
Note
- Before replacing a fuse check that the key has been removed from the ignition and that all the services are switched off and/or disengaged.
- Do not repair fuses and never replace a blown fuse with one that has a higher amp rating. This can cause damage to the ele ctrica l system and a fire.
- If a new fuse burns out again after short ly have you have installed it, have the electrical system checked by your authorized Audi dealer.
