The short version
- The 2009 to 2016 Audi A4 is ordered by measurement, and a 2010 Audi A4 wheel bearing front is either 513301 or 512574 depending on inner ring length.
- Later fronts, 2015 to 2016, add an outside diameter split, 512566 or 513379.
- Rears run one number, 512557, by inside diameter, for 2009 through 2015.
- 2009 fronts sit on a seam with the older body, so match the old part or run the VIN.
This page covers the 2009 to 2016 Audi A4, a body that drops year based logic almost entirely. A 2010 Audi A4 wheel bearing at the front is chosen by measuring the inner ring, not by reading a chart of years. The rear is more settled, but the front demands a tape measure or a VIN.
Audi A4 wheel bearing numbers by measurement
A 15mm inner ring length points to 513301. A 19mm inner ring length points to 512574. Both cover 2010 through 2016.
From 2015, outside diameter adds a further split, 80mm to 512566 and 85mm to 513379, with both listings running past the end of this body.

This page covers the 2009 to 2016 Audi A4: 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016. Other years live on the main Audi A4 wheel bearing page.
This body is ordered by measurement, not by year: ring length, outside diameter, and inside diameter all decide the correct number.
Measure the old bearing or run the VIN. Guessing between 513301 and 512574 for a 2010 Audi A4 wheel bearing is a coin flip without a measurement in hand.
Year by year
2009 sits on the seam with the earlier body. A carryover front number reaches into 2009. Match the old part or run the VIN rather than assuming it applies.
2010 through 2014 fronts split by inner ring length alone, 513301 for 15mm and 512574 for 19mm. The rear, 512557, holds steady across this stretch.
2015 and 2016 add the outside diameter rows, 512566 and 513379, on top of the existing ring length split. Model years from 2017 on belong to the next body, per the main model page.
A measurement based generation
Unlike the two earlier A4 bodies, this one leans on physical measurement instead of a clean year chart. That makes a tape measure more useful than a build date when a listing looks ambiguous.
The two earlier bodies use engine and drivetrain splits instead. See the 1996 to 2001 Audi A4 page and the 2002 to 2008 Audi A4 page.
Diagnosing an Audi A4 wheel bearing
- Pull the old bearing before ordering. Measure inner ring length and outside diameter rather than relying on the model year alone.
- Listen for a hum that builds with speed. This is the classic wheel bearing symptom on any generation of this car.
- Rule out the tires. Compare the sound to tire noise versus a wheel bearing first.
- Check for play at the hub. Follow the standard wheel bearing check with the wheel raised off the ground.
- Run the VIN on a 2009 front. The seam year needs a positive identification. Do not guess based on the model year printed on the title.
Common questions
What is the 2010 Audi A4 wheel bearing number up front?
A 2010 Audi A4 wheel bearing at the front is 513301 with a 15mm inner ring length. It is 512574 with a 19mm inner ring length. Measure before ordering.
What wheel bearing does a 2015 Audi A4 use?
A 2015 front may fall under the ring length split, 513301 or 512574. It may also fall under the newer outside diameter split, 512566 or 513379. Check both measurements on that year.
Why is this generation ordered by measurement instead of by year?
The catalogs document this body by physical dimensions rather than a clean year chart. A tape measure settles disputes a year lookup cannot.
Does the 2009 Audi A4 front use this body’s numbers?
Not necessarily. 2009 sits on a seam where a listing from the earlier body still reaches. Match the old part or run the VIN.
Is the rear bearing the same for every 2009 to 2015 A4?
Yes, one number, 512557, by inside diameter, covers the rear for that entire span in the catalogs we hold.
