For information regarding inspection service, refer to ServiceNet, Maintenance Schedules for appropriate model year CONTACT CORROSION Contact corrosion Contact corrosion can occur if improper fastening elements (bolts, nuts, washers, etc.) are used. For this reason, only fastening elements with a special surface coating are installed. These elements can be recognized by their green color. In addition, rubber, plastic parts and adhesive are made of non-conductive material. If there are doubts as to whether parts can be reused, install new parts. DESCRIPTION OF WORK All switches, all electrical components, all displays and other operating elements: Checking function  Check following:  Lighting, headlamps, fog lights, turn signals, hazard warning flashers, taillights, rear fog lights, backup lights, brake lights, parking lights  Interior and reading lights (automatic shutoff on interior lights), illuminated storage compartment, illuminated ashtray, luggage compartment lighting, illuminated ignition  Warning buzzer for lights and/or radio left on  All switches in console  MMI function (radio, navigation, etc.)  Driver Information System (DIS)  Instrument unit with all displays, meters and lights  Two-tone horn  Windshield/headlamp wipers, headlamp cleaning system  Cigarette lighter  Electrical exterior mirrors (heated, adjustable, foldable)  Electric windows WARNING:  Only using original Audi A8 parts!  Accessories must be approved by Audi AG!  Damage due to contact corrosion is not covered by warranty! 2006 Audi A8 Quattro Maintenance Maintenance Procedures - A8 & S8 FIXYOURCAR 2:15:08 AM Page 3

Wheel bolts The adapter to loosen/tighten the anti-theft wheel bolts is located with the vehicle tool kit. NOTE:  Be sure to tighten wheel bolts in diagonal sequence to the following specified torque: Tightening torque Nm 2006 Audi A8 Quattro Maintenance Maintenance Procedures - A8 & S8 FIXYOURCAR 2:15:08 AM Page 4

 Place adapter with vehicle tool kit after completing work. Correct wheel installation  When installing wheels, you must observe the following points to ensure wheels fit securely:  Always tighten wheel bolts to the specified torque so the wheel bolt seats in rim are not deformed.  When installing a wheel, do not tighten first wheel bolt immediately (for example, with an impact wrench). This would prevent other bolts from centering rim properly when they are screwed in. Rim could then become loose, even if tightened to specified torque.  Before installing wheels, check for rust/corrosion in wheel bolt seats and contact surfaces between rims and hubs, removing if necessary. Otherwise, the wheel bolts can lose tension after installation and the rim can come loose. Battery manager: Deactivate transport mode Transport mode is for maintaining a vehicles startability (battery charge). Transport mode limits discharging of battery. If transport mode is activated, many functions are not available or have limited function, for example, CD changer is deactivated, radio is deactivated, etc. Deactivate transport mode using guided fault finding or guided functions.  Follow these steps in sequential order. Fig. 2: Connecting Data Link Connector (DLC) Wheel bolts 120 WARNING:  If the above points are not observed, wheels can come loose and the wheel bolt seats in rim can be deformed.  The deformity could be so small that you can't see it.  But even small deformities in the wheel bolt seats can prevent the wheel from fitting securely, so that it becomes looser and looser. 2006 Audi A8 Quattro Maintenance Maintenance Procedures - A8 & S8 FIXYOURCAR 2:15:08 AM Page 5

 The magic eye - arrow - gives information about electrolyte level and battery charge.  Three color displays are possible:  Before performing visual check, carefully and lightly knock magic eye with handle of a screwdriver.  This removes air bubbles.  Read "magic eye" color display. Battery sealing plugs  On batteries with visible min and max markings, electrolyte level only needs to be checked visually.  Electrolyte level must be between min. and max. markings.  On batteries where the outer min. and max. markings are difficult to see or the visibility of the electrolyte level cannot be guaranteed due to the opaque battery housing, the sealing plugs must be removed. Then it is possible to check electrolyte level by a visual inspection of the battery interior.  The electrolyte level must meet the inner electrolyte level marking (plastic bar). This corresponds to the outer max. mark. Color display Battery level Green  Battery is sufficiently charged Black  No charge or charge too low Colorless or yellow  Electrolyte has reached critical level, battery must be replaced! --> 27 - BATTERY, STARTER, GENERATOR, CRUISE CONTROL NOTE:  If the battery was recharged, that is, if it was charged while driving, air bubbles can form under the magic eye. These cause an incorrect magic eye color display.  If batteries are equipped with plugs for production reasons, these are covered with plastic film. NOTE:  If electrolyte level is too low, battery loses capacity (loses performance) because the cell plates dry out. If the cell plates are not covered by electrolyte, the plates and plate bridges start to corrode causing the function of the battery to diminish. After a while the battery does no longer function. The battery becomes useless. WARNING: If the electrolyte level is below them in. marking, the battery must be replaced! --> 27 - BATTERY, STARTER, GENERATOR, CRUISE CONTROL 2006 Audi A8 Quattro Maintenance Maintenance Procedures - A8 & S8 FIXYOURCAR 2:15:08 AM Page 8
