What comes into the workshop is driveline work: the quattro system splitting drive front and rear, the propshaft and its support bearing, differential and axle seals, and a transmission that has usually spent its life in heavy stop-start miles. This manual covers the 2009 model year with the 4.2L V8 and the 6.0L W12.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e4.2L V8 GAS Naturally Aspirated\u003c\/li\u003e\n\u003cli\u003e6.0L W12 GAS Naturally Aspirated\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eTrims\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBase Sedan 4-Door\u003c\/li\u003e\n\u003cli\u003eL Sedan 4-Door\u003c\/li\u003e\n\u003cli\u003ePlus Sedan 4-Door\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe list above is carried from the same year's A8 quattro record, which covers the standard-wheelbase and long-wheelbase cars in one entry. That is a fair guide to the mechanical package, and on a driveline job it is fair right up to the point where length enters the equation: propshaft sections and their support bearing, rear brake and fuel lines and the harness runs beside them are specified to the body, along with rear cabin equipment and rear door hardware. Verify those against your own build data.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKnown issues on the 2009 A8 L.\u003c\/strong\u003e No recalls are on federal record for this model year. No complaints are logged with NHTSA for this model year. Driveline symptoms on a 2009 car are easy to misread. A vibration that arrives at a specific speed and disappears again usually points at the propshaft support bearing or its flexible coupling rather than at wheels or tires; a shudder under light throttle points at the automatic; a whine that changes with load points at a differential. Torn CV boots and seeping output and axle seals are cheap to fix early and expensive to ignore. Transmission fluid and pan service pays for itself here, and engine and gearbox mounts collapse quietly enough that people accept the extra harshness as normal. Everything the earlier cars are known for is still present: air suspension struts, compressor and sensors with their calibration step, front suspension bushings and bearings, chain tensioner rattle and cover seals on the V8, and coil, plug and access work on the W12.\u003c\/p\u003e\u003cp\u003eDriveline jobs on an all-wheel-drive car of this size go badly without correct sequence and preload, so the 2009 removal orders, tightening specifications, setting procedures, wiring layouts, capacities and intervals gathered here are the difference between a repair that settles and one that comes back.\u003c\/p\u003e","brand":"FactoryManual","offers":[{"title":"Default Title","offer_id":48892466331870,"sku":"AUDIA8L2009SRM","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/4113\/8910\/files\/9324153798878.png?v=1788107232","url":"https:\/\/factorymanual.com\/products\/2009-audi-a8l-service-repair-manual","provider":"FactoryManual","version":"1.0","type":"link"}
