When the ABS on an Audi 80 2.0 E Quattro requires attention, choosing a sensor ring with an exact fit is vital. This category covers dedicated components for four-wheel-drive saloon...
The Audi 80 2.0 E Quattro is renowned for its dependable four-wheel drive system and robust build, but keeping its advanced safety systems working properly requires intact components at every corner. An ABS ring, also known as an ABS reluctor ring, is a small yet critical part of the car's anti-lock braking system. On an older classic like the Audi 80, these rings are exposed to road grit, moisture and winter road salt over many years, which often causes severe corrosion or cracking. At CVJoint24, you will find dedicated parts engineered specifically for the Audi 80 2.0 E Quattro, ensuring your car stays safe on the road in all driving conditions. Maintaining the drivetrain on a Quattro model demands components built with pinpoint precision so that power transfer remains perfectly balanced.
Our range is carefully selected to meet the exact technical requirements of the 2.0 E engine paired with the Quattro system. Because these cars frequently tackle harsh European winters, the materials used in our ABS rings are chosen to offer superior resistance against rust and corrosion. Replacing a defective ring promptly prevents annoying warning lights and ensures the vehicle's brake force distribution operates just as the factory in Ingolstadt intended.
The ABS ring is mounted onto the CV joint and supplies a precise pulse signal to the car's ABS wheel speed sensor via magnetic induction. As the wheel turns, the sensor reads the teeth on the ring to calculate the exact wheel speed in real time. If a ring cracks or rusts through, the signal sent to the control module becomes erratic or drops out completely. On a Quattro model this is particularly critical, as the electronics do not just manage braking; they often work alongside traction systems to balance power delivery across all four wheels for optimal grip and stability.
A fully functional ABS ring is therefore vital for both the brakes and any traction systems to perform correctly. Without an accurate signal, the car's ECU cannot tell whether a wheel is locking up or losing traction. This can trigger unwarranted ABS intervention at low speeds or cause the system to shut off entirely for safety, leaving you without anti-lock protection in an emergency. Consequently, this modest reluctor ring is one of the most critical safety components on your vehicle.
The most frequent sign of a failed ABS ring on your Audi 80 2.0 E Quattro is the ABS warning light illuminating on the dashboard, either constantly or intermittently. Drivers also often experience false ABS activation. This occurs when the ABS pump kicks in and pulses through the brake pedal during gentle stops at low speeds on dry tarmac. A cracked ring creates an irregular gap in the tooth pattern, misleading the computer into thinking that the wheel has suddenly locked.
A visual check, typically done with the wheel removed, will reveal telltale cracks or swelling caused by rust building up between the ring and the outer CV joint. As rust expands, it forces the ring outwards until it splits or rubs against the sensor tip. If you notice a scraping noise from the wheel arch that changes pitch with vehicle speed, the ABS ring may have come loose or deformed enough to make contact with the sensor, which will quickly ruin the sensor as well.
Selecting the right ABS ring requires close attention, as the tooth count and inner diameter can vary depending on the chassis number and drivetrain configuration. For the Audi 80 2.0 E Quattro, you must verify that the ring matches the dimensions of the outer CV joint where it is installed. Installing a ring with the wrong tooth count produces an incorrect road speed signal, preventing the ABS unit from calibrating properly and leaving fault codes permanently stored.
The simplest way to identify the correct part is to select your car by make, model and engine variant in our store. We have cross-referenced our products against original technical data so you can order with confidence without having to measure rusty parts in your garage. When fitting the new part, thoroughly clean all corrosion from the mounting seat on the constant velocity joint so the ring sits true and flat. Warming the new ring gently before installation allows it to expand slightly and then shrink-fit securely in place as it cools, guaranteeing a long-lasting fit.

Whenever a drivetrain component wears out, it is wise to inspect the neighbouring parts at the same time. By checking these matching pages for the Audi 80 2.0 E Quattro, you can quickly determine whether an issue stems solely from the ABS ring or another connected driveline part.
This is especially important on four-wheel-drive models, where vibrations, play and unusual noises can travel across multiple components in the drivetrain. Taking a moment to check related categories helps ensure you cure the underlying issue without overlooking adjoining wear.

The most common symptoms are an illuminated ABS warning light or the brake pedal pulsating during gentle braking on dry roads. A visual inspection often reveals cracks in the ring.
No, on an Audi 80 2.0 E Quattro you can usually replace just the ABS ring. This is a cost-effective solution provided the CV joint itself is otherwise in good condition.
The tooth count can vary depending on the model year and specification. The most reliable way to find the correct number is to select your vehicle's exact make, model and engine variant on our site.
It is primarily caused by corrosion. Rust builds up beneath the ring on the CV joint, creating outward pressure that eventually causes the hardened steel ring to crack.
Yes, because the all-wheel drive and stability systems rely on wheel speed data, an erratic signal from a damaged reluctor ring can disrupt system operation.
It requires removing the CV joint from the wheel hub. The new ring is then pressed or heat-shrunk into place after thoroughly cleaning the mating surface.
