Audi Relay Boxes Parts and Q&A
- Q: How do Fuse Box and Relay Boxes protect circuits from excessive current flow on Audi A3?A:Fuses are set up to interrupt a circuit once a specific current level is surpassed as a safety measure to prevent damage to components and wiring in case of too much current flow, which is normally as a result of a fault such as a short-circuit. The fusebox is on the drivers side of the facia; it is accessed by unclipping the fusebox cover when the driver has opened the door with the positions of the fuses indicated on the back of the cover. Enabling the removal of a fuse, it is necessary to switch off the circuit or ignition and then extract the fuse out of the terminals, a blown fuse will have a piece of wire or be melted. Never use a fuse of a different rating, but it is always possible to replace them with the right rating. The bottom has a stamped fuse rating which is colour-coded. When the fuse keeps blowing, locate the cause of the inconvenience and then install the same fuse once more, because in this case, short to earth caused by insulation defects is probable. To circuits which have only one fuse, isolate the fault by turning on the circuits until the fuse blows once more, and have spare fuses of the appropriate value in the car. Further fuses and relays can be found in the fusebox high up on the left of the engine compartment, which has an unclipped fuse holder cover. To replace a fusible link, remove the negative terminal of the battery, unscrew the retaining nuts, remove the blown link, replace it with a new one, reconnect the lead, make sure that the retaining nuts go into place, replace them and install them again and fix the battery. A relay is a switch, controlled by electricity, which may turn heavy current on and off remotely, may have many inputs to control it, may have timer facilities. Another connection is that most of the relays are in the relay plate behind the driver side facia, and the other relays in the engine compartment fusebox. To gain access to the relays one has to take the lower facia of the driver side panel away. When a circuit operated by a relay faults, use the system to see whether the relay clicks when energised, in this case the fault is in the components or wiring of the system. When the relay does not energise it is possible that it is not being powered or is faulty and this can be tested by replacing it with a known good unit. To remove a relay, make sure that the corresponding circuit is switched off then pull it out of the socket and squeeze it back. The hazard-warning switch is provided with a direction indicator/hazard flasser relay.
- Q: Where are the Fuse Box and Relay Boxes located, and how can they be accessed and replaced on Audi 100?A:Fuses are found in the fusebox behind the end cover on the driver's side of the facia panel, with additional fuses, including automatic circuit breakers, located in the fuse/relay box in the rear corner of the engine compartment. More fuses can be accessed behind the front footwell side trim panels and the footwell floor plastic cover. To access the fusebox, open the driver's side door and unclip the end cover from the facia. For the engine compartment fuses, release the retaining clip and remove the cover from the fuse/relay box. Each fuse protects specific circuits, and to remove a fuse, switch off the relevant circuit or ignition, then pull the fuse out; a blown fuse will show a broken or melted wire. Always replace a fuse with one of the same rating, as indicated on the fuse, and avoid using a different rating or substituting anything else. If a new fuse blows immediately, investigate the cause, as faulty insulation may be the issue. Spare fuses of each relevant rating should be kept in the vehicle. Most relays are located in the fuse/relay box in the engine compartment or behind the driver's side facia storage compartment panel and footwell side trim panels. Access to the engine compartment relays is gained by removing the lid, while those behind the driver's side storage compartment require removing retaining screws and the panel. To access footwell trim panels, remove the trim strip and screws, with relay details available on a sticker on the rear of the panel. If a relay-controlled circuit develops a fault, listen for a click when the system is operated; if no click is heard, the relay may not be receiving power or could be faulty. Testing can be done by substituting with a known good relay, keeping in mind that while some relays may look identical, they can perform different functions. To replace a relay, ensure the ignition is off, pull out the old relay, and press in the new one.
