Audi S3: Gearbox repair techniques

The S3 is also available as a Sedan: the 50 TFSI 300 Quattro S Tronic 7 Sedan is equipped with a seven-speed automatic gearbox. The Cabriolet version is available with an S-Tronic transmission or a six-speed manual gearbox. The Audi S3 is sometimes chosen in its Sportback version, as in the case of the Sportback 2.0 TFSI 265 Quattro BV6, which features a six-speed manual gearbox. 

S-Tronic is an Audi signature : a robotized dual-clutch transmission that enables automatic gear changes without torque interruption. It is available on most S3 versions from the second generation onwards.

Despite the sturdiness of the S3, the gearbox can sometimes break down: EDEN BOITES has some tips on how to repair it.

How do I change the transmission oil in my Audi S3 gearbox?

The role of gearbox oil

Gearbox oil has three major roles. Firstly, it reduces friction between gearbox components by ensuring effective lubrication. It also dissipates the heat generated during driving, preventing the transmission system from overheating. Finally, transmission oil helps to maintain the integrity of the seals, making the gearbox watertight.

Regularly checking the level and appearance of your gearbox oil can help prevent sometimes irreversible damage to your vehicle's entire transmission.

How do I change the oil in my gearbox?

Changing the gearbox oil is a relatively simple process involving the following steps: 

• Park your vehicle on a level surface;
• Locate the transmission oil sump under the car, near the engine;
• Place a drip tray under the crankcase;
• Carefully remove the housing after loosening the fixing bolts;
• Let the oil drain into the sump, clean the housing and replace the seals if necessary;
• After reinstalling the crankcase in its housing, remove the dipstick and pour in the correct oil for your gearbox;
• Now check that the oil level is between the two marks on the dipstick, and top up if necessary;
• Start the engine and let it run for a few minutes to circulate the new oil;
• Observe whether oil is leaking from the crankcase or dipstick;
• Drive smoothly through the various gears and notice how smoothly the gears change.

How to prevent and manage an Audi S3 gearbox failure?

Taking care of your gearbox

Whatever type of gearbox you choose, you need to drive smoothly to extend the life of your transmission system. This means paying close attention to your surroundings, so as to anticipate any acceleration or braking by other motorists.

For manual gearboxes, it's important to change gears according to engine noise and rpm, generally around 2500 rpm. Gentle handling of the gearshift and clutch pedal is also a good way of protecting your gearbox.

For automatic gearboxes, itis essential to bring the vehicle to a complete stop before engaging the Park or Reverse positions.

Identify signs of failure

The most common symptom of a gearbox problem is difficulty shifting gears due to heavy resistance at the gearshift. A burning smell or unusual noises are also typical of a transmission system failure:

• A dull whirring sound is a sign of worn bearings at the end of the axles;
• A cracking sensation when shifting gears indicates premature wear of the synchronizer rings;
• A whistling noise is often a symptom of low transmission oil.

Finally, if you notice a general decline in your vehicle's performance, such as a loss of power or a marked reduction in acceleration, don't delay in contacting a mechanic for a precise diagnosis.
