This page covers the 2012-2018 Audi A6: 2012, 2013, 2014, 2015, 2016, 2017, 2018. Other years live on the main Audi A6 wheel bearing page.
A 2012 Audi A6 wheel bearing follows the ring length rule up front. That rule stops in 2018, when the front has no documented listing.
On a 2018 car, match the front to the old part or run the VIN. Do not carry the 2012-2017 front rows forward onto it.
Year by year
2012 through 2017 share the same front split: 513301 for 15mm, 512574 for 19mm inner ring length.
The rear stays at 512557 for that same six year stretch.
2018 breaks the pattern: the rear moves to 512598, and the front is matched to the old part or the VIN.
A table that changes shape at the end
Six of the seven model years share one clean set of listings, front and rear alike.
The seventh, 2018, is the outlier: a new rear number and a front gap the earlier years do not have.
Cars built before 2012 are covered on a separate table rather than this one.
Diagnosing an Audi A6 wheel bearing
- Listen for the noise. A worn bearing usually growls or hums, and the sound tracks road speed, not RPM. Wheel bearing noise on turns covers the pattern.
- Rule out the tires. Uneven tread wear can sound like a bad bearing. Tire noise or wheel bearing helps tell them apart.
- Check for play. With the wheel off the ground, rock it top and bottom to check for looseness. How to check a wheel bearing walks through it.
- Measure the front on a 2012-2017 car. Pull the old bearing and check the inner ring length before choosing.
- Match the old part on a 2018 front. With no documented number for that position, use the old bearing’s markings or the VIN.
