Audi TSI DSG

In late 2008, an all-new seven-speed longitudinal S tronic version of the DSG transaxle went into series production (Volkswagen Group internal code: DL501, parts code prefix: 0B5), led by Audi transmission design engineer Mario Schenker. Initially, from early 2009, it is only used in certain Audi cars, and only with longitudinally mounted engines. Like the original six-speed DSG, it features a concentric dual wet multi-plate clutch. However, this particular variant uses notably more plates — the larger outer clutch (for the odd-numbered gears) uses 10 plates, whereas the smaller inner clutch (driving even-numbered gears and reverse) uses 12 plates.Another notable change over the original transverse DSGs is the lubrication system — Audi now utilize two totally separate oil circuits. One oil circuit, consisting of 7.5 litres , lubricates the hydraulic clutches and mechatronics with fully synthetic specialist automatic transmission fluid (ATF), whilst the other oil circuit lubricates the gear trains and front and center differentials with 4.3 liters of conventional hypoid gear oil.This dual circuit lubrication is aimed at increasing overall reliability, due to eliminating cross-contamination of debris and wear particles.It has a torque handling limit of up to 600 N·m (440 lb·ft) and engine power outputs of up to 330 kW (450 PS; 440 bhp). It has a total mass, including all lubricants and the dual-mass flywheel of 141.5 kg.
This was initially available in their quattro all-wheel-drive variants, and is very similar to the new ZF Friedrichshafen-supplied Porsche Doppel-Kupplung (PDK).

Ok, tämä koskee vain niitä Audeja joissa kone pitkittäin. Ei siis koske ainakaan A3:sta ja A1:stä. Mites päin kone on nykyisissä A4:issa?

Eipä kyllä kiinnosta

Ei kummoinen mutta sillä vaan pärjättävä - perusperhedieselillä.
