Alongside the 4.2L V8 sits a 6.0L W12 that fills the engine bay differently, reroutes cooling and accessory drive, and pushes far more routine work into the service position with the front end drawn forward. This manual covers the 2005 car with both engines and keeps the two apart wherever the procedures diverge.\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\u003eL Plus Sedan 4-Door\u003c\/li\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 trims and engines above are drawn from the same year's A8 quattro record, which lists both wheelbase lengths together, and the L Plus entry in it is a long-wheelbase designation rather than a separate mechanical package. The long car shares its powertrain and running gear with the standard-wheelbase version, so engine and transmission procedures carry over unchanged, but rear cabin content, rear door and window hardware and wheelbase-dependent parts should be checked against your car's equipment record before you order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKnown issues on the 2005 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. On the shop floor the work splits by engine. W12 cars concentrate on access and ignition: twelve coil packs and plugs, a misfire that has to be traced cylinder by cylinder instead of guessed at, an intake assembly that comes off for a surprising amount of routine work, and cooling components buried behind it. V8 cars bring the familiar cold-start chain tensioner rattle and oil weeping from the chain cover and cam adjuster seals. Both share the air suspension, meaning leaking struts, a tired compressor, ride-height sensors and the calibration that follows any repair, along with front control-arm bushings, wheel bearings, and Tiptronic service that is worth doing on time even though the fluid was sold as a lifetime fill.\u003c\/p\u003e\u003cp\u003eTwo very different engines under one body shell is exactly the situation where a year-correct manual earns its keep, and this one carries the 2005 removal sequences, tightening specifications, wiring layouts, capacities and intervals for the V8 and the W12 without blurring them together.\u003c\/p\u003e","brand":"FactoryManual","offers":[{"title":"Default Title","offer_id":48892433563870,"sku":"AUDIA8L2005SRM","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/4113\/8910\/files\/9324153536734.png?v=1788107210","url":"https:\/\/factorymanual.com\/products\/2005-audi-a8l-service-repair-manual","provider":"FactoryManual","version":"1.0","type":"link"}
