The short version
- A 2015 Audi A3 wheel bearing at the front is either 512566 or 513379. The outside diameter of the old bearing decides which one, not trim or drivetrain.
- The rear is 512336 on front wheel drive cars, or 512566 on quattro cars built in 2015 or 2016.
- 512566 does double duty as a front listing and as the 2015-2016 quattro rear listing. Match the position, not just the number.
- 2017 quattro cars have no documented rear listing. Match the old part or run the VIN.
Audi restarted the A3 nameplate for 2015. The front wheel bearing on this generation splits by a measurement, not a trim level.
A 2015 Audi A3 wheel bearing at the front is 512566 on an 80mm hub or 513379 on an 85mm hub. The only way to tell them apart is to measure the old part.
The core numbers
Front hubs measuring 80mm outside diameter take 512566. Hubs measuring 85mm take 513379.
The rear is 512336 on front wheel drive cars. It is 512566 on 2015-2016 quattro cars, the same number used at the front elsewhere in this range.

This page covers the 2015-2017 Audi A3: 2015, 2016, 2017. Other years live on the main Audi A3 wheel bearing page.
A 2015 Audi A3 wheel bearing at the front is not decided by trim or drivetrain. It is decided by measured outside diameter. Put calipers on the old hub before ordering 512566 or 513379.
512566 is not exclusive to one position on this car. It is the smaller diameter front listing, and separately, the 2015-2016 quattro rear listing.
A 2017 quattro car has no rear listing in this range. Match the old part or run the VIN, do not reuse the 2015-2016 number.
Year by year
2015 and 2016 share every row here: both front diameters, the front wheel drive rear, and the quattro rear. 2017 drops the quattro rear listing. That position falls to the old part or the VIN while the rest of the car keeps the same numbers.
How this range differs from the earlier A3
This 2015-2017 car replaced the numbers used on the 2006-2008 Audi A3 wheel bearing page. None of those earlier part numbers carry forward.
Diameter measurement matters more here than drivetrain by itself. That is a different split than the drivetrain based rule on the older car, see drive type and wheel bearings.
Diagnosing an Audi A3 wheel bearing
- Pull the old hub. A 2015 Audi A3 wheel bearing cannot be identified from year and trim alone.
- Measure the outside diameter. An 80mm hub takes 512566, and an 85mm hub takes 513379.
- Confirm the drivetrain for the rear. Front wheel drive cars take 512336, and 2015-2016 quattro cars take 512566.
- Check the model year on a quattro rear. A 2017 quattro rear has no documented listing, so match the old part or run the VIN.
- Listen before removing anything. A failing bearing on this car often growls at speed, see wheel bearing noise when turning.
Common questions
What wheel bearing does a 2015 Audi A3 use?
A 2015 Audi A3 wheel bearing at the front is 512566 or 513379 by measured outside diameter. The rear is 512336 on front wheel drive or 512566 on quattro.
What wheel bearing does a 2017 Audi A3 use?
A 2017 Audi A3 uses the same front numbers as 2015 and 2016. The quattro rear has no documented listing that year, so match the old part or run the VIN.
How do I know if my A3 front hub is 80mm or 85mm?
Measure the outside diameter of the old bearing directly. Trim level and options do not reliably show which size is fitted.
Does the quattro A3 use the same rear bearing as the front wheel drive car?
No. Front wheel drive cars use 512336 at the rear. 2015-2016 quattro cars use 512566, which is also a front listing on this car.
Why is there no 2017 quattro rear wheel bearing number?
The catalogs do not carry a 2017 quattro rear listing. That position is not documented, match the old part or run the VIN.
