The Audi S5 gearbox is at the heart of one of the most compelling sporting variants of the A5 coupé. Launched in 2007 with a V8 engine, four exhaust outlets and a 6-speed manual gearbox, the Audi S5 has since evolved: from 2017, the S5 (5F) in sportback, coupé and cabriolet forms adopted an 8-speed automatic gearbox. The transmission plays a decisive role in both the driving pleasure and the performance of the car.
To help you get the most from your coupé, EDEN BOITES explains the role of the gearbox, the characteristics of those fitted to the Audi S5, the maintenance it requires, and what to do when a fault arises.
What does the gearbox do?
The gearbox is essential to the car's operation — without it, nothing moves. Connected to the drivetrain, it converts engine revolutions into wheel rotation and allows you to select the ratios that govern the power delivered. Changing gear alters the meshing of the cogs and transmits a new level of power to the driveshafts and, in turn, to the wheels.
The characteristics of the Audi S5 gearbox
The Audi S5 is generally fitted with a 6-speed manual gearbox, as on the 4.2 FSI quattro 4x4 version. The latest generation, however, offers an 8-speed automatic gearbox. The Audi S5's V8 produces 354 bhp at 6,800 rpm and sprints from 0 to 100 km/h in 5.1 seconds. Fuel consumption, on the high side at 12.4 l/100 km, drops to 10.8 l with the automatic gearbox. To compare the two types of transmission, see our guide on the differences between a manual and an automatic gearbox.
How do you maintain the Audi S5 gearbox?
To prevent wear-related problems, the Audi S5 gearbox requires an oil change every 60,000 kilometres or every 4 years. A gearbox running low on oil deteriorates very quickly and can lead to costly repairs. A service is also recommended between 15,000 and 30,000 kilometres, or at least every 2 years. Don't forget the timing belt, which should be replaced at around 90,000 kilometres.
When should I repair the Audi S5 gearbox?
Several warning signs should put you on alert, particularly while driving. A crunching noise when changing gear or a gear becoming stuck are tell-tale symptoms. They generally point to a clutch fault, worn gearbox cogs, or insufficient lubrication. Acting on these signs promptly with a quick diagnosis will prevent the damage from worsening.
How do you repair the Audi S5 gearbox?
The repair begins with removing the gearbox. On the Audi S5, the engine block sits particularly far back and the front wheels are pushed well forward to balance the weight distribution, so an extra pair of hands is often needed. On a manual gearbox, you should then check:
- the driveshafts, their gears and lubrication;
- the synchro rings, whose teeth must remain well-formed;
- the bearings and pinions, for any signs of corrosion;
- the oil seals, which should be replaced if worn.
This initial inspection will tell you whether replacing a few parts will suffice or whether the gearbox on your S5 needs to be replaced entirely. If in doubt, consult a professional — only they can confirm the true condition of the transmission. Fans of similar sporting models in the range will find our guides on the Audi S4 and the Audi A5 equally useful.
Frequently asked questions about the Audi S5 gearbox
Which gearbox does the Audi S5 have?
Depending on the generation, the Audi S5 is fitted with either a 6-speed manual gearbox or, on the most recent version, an 8-speed automatic gearbox.
How often should the Audi S5 gearbox oil be changed?
An oil change is recommended every 60,000 kilometres or every 4 years, with an interim service between 15,000 and 30,000 kilometres.
What are the signs of a failing Audi S5 gearbox?
A crunching noise when changing gear, a gear becoming stuck, or a loss of power often indicate worn cogs, a clutch problem, or insufficient lubrication.
Should I repair or replace the Audi S5 gearbox?
It all depends on the diagnosis. Limited wear can be addressed by replacing a few parts; more serious damage warrants an exchange unit, which is safer and often more cost-effective.
