ABS rings for Audi A4 2.8. Always check the fit before ordering.
The most reliable way is to select your car's make, model and engine variant in our search filter. We then match the part's specifications, such as tooth count and diameter, against your specific car model.
On the Audi A4 2.8, you can usually replace just the ABS ring if the CV joint is otherwise in good condition. The ring is pressed into place once the mating surface has been thoroughly cleaned.
This can be caused by several issues, but a cracked or heavily corroded ABS ring is a very common cause. When the ring fails, the sensor cannot read wheel speed correctly.
It requires removing the CV joint from the wheel hub. Once the joint is free, the old ring can be removed and the new one pressed or heat-shrunk into place.
Besides the ABS warning light staying illuminated, you may experience erratic braking behaviour when slowing down. It is a safety hazard and will cause the vehicle to fail its roadworthiness test (such as an MOT).
In many cases, the warning light goes out on its own after a short drive once the system receives correct signals again, though clearing the codes with a diagnostic scan tool may occasionally be required.
