Home › Vehicles › Audi › Audi S3 Wheel Bearing Part Numbers
The short version
- The Audi S3 wheel bearing chart splits by bearing outside diameter, not by trim or engine.
- 2015-2017 front bearings come in two versions. 512566 covers the 80mm outside diameter case, and 513379 covers the 85mm case.
- The 2014 front 80mm case uses a different number again, 513262. The 80mm row changes at the 2015 model year.
- 2014-2017 rear bearing is 512566, the same number as the 2015-17 front 80mm case. It does double duty at two positions.
Audi did not split the S3 front bearing chart by trim level or engine code. It split it by the outside diameter of the bearing case. One resulting number turns up twice on the same car.
Audi S3 wheel bearing quick reference
Measure the bearing outside diameter before ordering a 2015-2017 S3 front bearing. 80mm cases take 512566, and 85mm cases take 513379.
512566 also covers the rear position across 2014-2017. The same part number can be correct at two different corners of the same car.

Two front bearings exist for 2015-2017 S3 models, split by outside diameter rather than by trim. Measure the old bearing, or match the part already on the car, before buying.
512566 is not a mistake when it shows up as both a front 80mm bearing and a rear bearing on the same S3. Confirm position, not just the number.
Shared hardware with the Audi A3
The S3 rides on the same platform as the Audi A3. The A3 chart carries the identical 512566 and 513379 split. A shop stocking for one car has effectively stocked for the other.
Audi’s wider lineup, including the A4, uses its own numbers. Treat the A4 as a separate chart even though the badges look related.
See the full Audi lineup for related charts across the brand’s other sedans and hatchbacks.
Quattro duty on the S3
Every Audi S3 trim runs through the quattro all wheel drive system. Drive torque routes through the front hubs as well as the rear. That added front load is one reason to confirm the exact outside diameter.
Audi’s other quattro performance models, like the S4, do not get a dedicated wheel bearing catalog line the way the S3 does. The S3’s own documented split is the exception, not the rule.
Diagnosing an Audi S3 wheel bearing
- Listen for a load sensitive drone. A bad bearing gets louder under cornering load as weight shifts onto the worn side.
- Rock the wheel at 12 and 6 o’clock. Play with the brake released points at the bearing rather than the suspension.
- Watch for a wheel speed sensor fault. The S3 hub integrates the ABS sensor, so a failing bearing can set a code early.
- Measure the old bearing outside diameter before ordering. Confirm 80mm or 85mm rather than assuming from trim or year alone.
- Match position as well as number. 512566 appears at both the front 80mm case and the rear, so note where the old part came from.
Common questions
How do I know if my Audi S3 needs the 80mm or 85mm front bearing?
Measure the outside diameter of the bearing removed from the car, or match the number stamped on the old part. Trim level alone does not tell you which case your S3 has.
Does 512566 fit the front and the rear of the same S3?
Yes, but not by coincidence. It is the correct number for the 2015-2017 front 80mm case and separately for the 2014-2017 rear.
What front bearing does a 2014 Audi S3 use?
513262, a different number from the 512566 that covers the 80mm case from 2015 onward. Do not carry 512566 backward onto a 2014 car.
Does the Audi A3 use the same wheel bearings as the S3?
Yes. The A3 chart carries the same 512566 and 513379 front split, since both cars share the same platform.
Are all Audi S3 wheel bearing numbers the same across quattro trims?
Yes. The catalogs do not split by trim level, only by bearing outside diameter for the front position and by one number for the rear.
