Gearboxes

Gearbox	Audi code	Used with	Notes
6-speed manual	0DJ ML322-6F / 0CS ML402-6F	1.4 TFSI 150PS, 2.0 TFSI 190PS, 2.0 TDI 150PS, 2.0 TDI ultra 150PS, 2.0 TDI 190PS, 2.0 TDI ultra 190PS	Manual is listed only on front-wheel-drive four-cylinder models in this PDF.
7-speed S tronic	0CK DL382-7F / 0CL DL382-7Q	2.0 TFSI 190PS, 2.0 TFSI quattro 252PS, 2.0 TDI 150PS, 2.0 TDI ultra 150PS, 2.0 TDI 190PS, 2.0 TDI ultra 190PS, 2.0 TDI quattro 190PS, 3.0 V6 TDI 218PS, 3.0 V6 TDI quattro 218PS	The 0CK is the front-wheel-drive version; the 0CL is the quattro version.
8-speed tiptronic	0D5 AL552-8Q	3.0 V6 TDI quattro 272PS	The PDF reserves tiptronic for the 600Nm 3.0 V6 TDI quattro. SSP 644 identifies it as the AL552-8Q quattro gearbox.

The B9 uses the newer DL382 gearbox for the 7-speed S tronic models. On European-market B9 cars, the ZF 8HP automatic is only used with the 3.0 TDI 200kW engine.

Quattro systems

In this 2017 UK guide, quattro is available only on specific higher-output automatic models. Do not confuse TDI ultra with quattro ultra: in this PDF, “ultra” refers to efficiency-focused diesel models, not the later quattro ultra drivetrain branding.

quattro model	Power	Gearbox	Gearbox code	Notes
2.0 TFSI quattro	252PS	7-speed S tronic	0CL	Petrol quattro model listed across Sport and S line.
2.0 TDI quattro	190PS	7-speed S tronic	0CL	Four-cylinder diesel quattro option.
3.0 V6 TDI quattro	218PS	7-speed S tronic	0CL	V6 diesel quattro option.
3.0 V6 TDI quattro	272PS	8-speed tiptronic	0D5	Highest-output diesel quattro option, listed on S line.

Front-wheel-drive models in the PDF include the 1.4 TFSI, 2.0 TFSI 190PS, 2.0 TDI 150PS and 190PS, the 2.0 TDI ultra variants, and the 3.0 V6 TDI 218PS.

The brochure describes quattro as automatically distributing power between all four wheels according to grip. It does not list the mechanical centre-differential details, so confirm the exact drivetrain hardware from the VIN, PR codes or factory build sheet when comparing individual cars.

ETKA gives a useful clue about the hardware. For the 7-speed S tronic, gearbox 0CL is listed with a self-locking centre differential, while 0CJ is listed as “ultra quattro” with an oil-filled four-wheel coupling. For the 8-speed automatic, gearbox 0D5 is also listed with a self-locking centre differential. In other words, not every B9 quattro setup is the same: some cars use the traditional centre-differential quattro layout, while ultra quattro cars use a coupling-based system.

ETKA code	Gearbox	quattro hardware
0CL	7-speed S tronic	Self-locking centre differential
0CJ	7-speed S tronic	ultra quattro four-wheel coupling, oil-filled
0D5	8-speed tiptronic	Self-locking centre differential

Technical notes from SSP 644

Audi SSP 644 is a service training document for the A4 (8W). It is not a repair manual, but it has useful technical context that the sales brochure does not show.

Area	Useful detail
Body and aero	The A4 sedan has a claimed drag coefficient of 0.23; Avant is 0.26. Length is 4726mm and wheelbase is 2820mm. Boot volume is listed as 480 litres for sedan and 505 litres for Avant. SSP 644 says the body is 15kg lighter than the previous A4 (8K), using a mix of steels plus cast aluminium parts.
Fuel tank	Front-wheel-drive cars use a 40-litre tank as standard, with a 54-litre option. quattro cars use a 58-litre tank.
SCR / AdBlue	Diesel cars have SCR. SSP 644 lists two AdBlue tank sizes: 12 litres and an optional 24-litre version for longer range between refills.
Chassis platform	The B9 A4 is based on MLBevo. SSP 644 describes newly developed five-link front and rear suspension, with component design related to the Audi Q7 (4M).
Suspension codes	1BA is standard suspension. 1BE is sport suspension, about 23mm lower. 1BR is rough-road suspension, about 13mm higher. 1BQ is adaptive sport suspension with damping control, same ride height as 1BE. 1BL is adaptive comfort suspension with damping control, about 10mm lower than standard.
Service intervals	Flexible oil service is 15,000km / 1 year up to 30,000km / 2 years depending on use. Inspection service is 30,000km / 2 years. Cabin filter is 60,000km / 2 years. Engine air filter is 90,000km. Brake fluid is after 3 years, then every 2 years. S tronic oil interval is 60,000km.
Timing drive	SSP 644 lists timing belts for 1.4 TFSI and 2.0 TDI at 210,000km. 2.0 TFSI and 3.0 V6 TDI are listed as chain-driven with no scheduled replacement in the maintenance table.

Headlight types

There are three headlight types - Xenon, LED and Matrix LED.

PR	Headlight type
Standard	Xenon headlights with LED daytime-running lights
