About this part
The 2H0927807A ABS sensor pair is a brand new genuine OEM rear axle wheel speed sensor set for the Volkswagen Amarok 2H pickup, covering the left hand sensor 2H0 927 807 A and the right hand sensor 2H0 927 808 A. Both units are active Hall effect sensors built by ATE, part of the Continental group, with a two pin D shaped connector, a moulded mounting arm with a single fixing hole, an O ring sealed probe body and a short captive lead that clips back into the rear axle harness. The laser marking on the connector housing reads 2H0 927 807 A or 2H0 927 808 A together with the ATE production number 10.0711-6251.3, and the VW roundel is moulded into the plastic. These are the sensors bolted to the rear wheel bearing housings, where they read the magnetic encoder ring integrated into the wheel bearing and report rear wheel speed to the ABS and ESP control unit. They are fitted across the Amarok range from 2010 to 2022, on 2.0 TDI, 2.0 BiTDI, 2.0 TSI and 3.0 TDI engines, in both rear wheel drive 4motion and single axle drive form, as well as on the platform and chassis cab variants. When a rear wheel speed signal drops out, the dashboard normally lights the ABS and ESP warning lamps, traction control and hill hold are disabled, and the cruise control may refuse to engage, which is why these sensors are one of the first checks on an Amarok with a persistent ABS fault.

What you receive
This listing is for one pair of two sensors. You receive one 2H0927807A sensor for the rear left side and one 2H0927808A sensor for the rear right side, exactly as shown in the photographs. The two sensors are mirror images of each other, with the mounting arm and the lead exiting on opposite sides, so a single sensor cannot be fitted to both corners. The tiered pricing below applies to 1 pair, 5 pairs and 20 pairs respectively, which suits independent workshops and fleet operators that keep rear axle sensors on the shelf for Amarok maintenance. If you only need one side, please contact us before ordering so we can confirm which corner you need and quote the correct single unit.
The front axle of the same vehicle uses completely different sensors, listed as WHT003856, WHT003857, 7H0927803 and 7H0927804. Those front sensors are not included in this pair and are not interchangeable with these rear sensors. The pair is supplied as the two bare sensors with their moulded O rings and connectors; the fixing bolts, wheel bearing encoder rings, harness repair sections and any ABS control unit are not included. VW generally specifies a new fixing bolt and a clean mounting bore whenever a sensor is removed, so have those to hand before starting the job.
What an active wheel speed sensor does and why it fails
Reading the magnetic encoder ring. Unlike the older passive inductive sensors that generated their own sine wave from a toothed reluctor ring, this Amarok sensor is an active Hall device. It is supplied with a regulated voltage from the ABS control unit and switches its output between two current levels as the alternating north and south poles of the magnetic encoder ring, sealed inside the rear wheel bearing, pass the tip of the probe. Because the output is a clean square wave at a fixed amplitude, the ABS unit can resolve wheel speed down to walking pace and can even detect the direction of rotation. That low speed accuracy is what makes hill hold, traction control, electronic differential lock, trailer stabilisation and the 4motion coupling respond correctly on a pickup that is often driven on loose surfaces.
How a failing sensor shows up. The most common failure is a break in the two core lead where it flexes beside the trailing arm, or water tracking into the connector after a pressure wash or a winter of road salt. That produces an intermittent open circuit and a wheel speed signal that vanishes for a fraction of a second, which the ABS unit logs as an implausible or missing rear wheel speed signal. The driver sees the ABS lamp, the ESP or ASR lamp, sometimes a parking brake or hill hold warning, and may feel the ABS cutting in unexpectedly at low speed because one wheel appears to be stationary. Cruise control and the speedometer can also be affected where the instrument cluster takes its speed from the same wheel speed data. Corrosion at the sensor tip, a swollen or cracked O ring, a loose fixing bolt that lets the probe lift away from the bearing, and a damaged or demagnetised encoder ring on a cheap replacement wheel bearing all produce the same family of faults, so a live data comparison of all four wheel speeds during a slow road test is the quickest way to separate a bad sensor from a bad bearing or a harness problem. Typical fault codes are recorded as a mechanical or electrical failure of the rear left or rear right wheel speed sensor, but a scan alone cannot tell you which of the sensor, the wiring or the encoder ring is at fault.
Why replace the pair. Both rear sensors on an Amarok share the same mileage, the same exposure to mud, water and salt, and the same harness routing. If one has corroded through, the other is usually close behind. Replacing both sides together avoids a second breakdown a few weeks later, keeps the signal amplitudes matched at both rear wheels and removes the risk of an intermittent fault on the opposite corner confusing the diagnosis. It is also the cheapest way to buy them, which is why this listing is offered as a pair rather than as individual sensors.
Part number confusion: rear axle sensors, not front axle sensors
Four very similar numbers, two different axles. Please read this before ordering, because Amarok ABS sensor listings are frequently bundled together. This pair, 2H0927807A and 2H0927808A, is for the rear axle: 807A is the rear left sensor and 808A is the rear right sensor. The front axle uses WHT003856 and WHT003857, also catalogued as 7H0927804 and 7H0927803. Those front sensors have a different probe length, a different mounting arm, a different lead length and a different connector position; they will not bolt into the rear bearing housing and must not be substituted. Many marketplace listings sell a four sensor kit that mixes both axle types and print all eight numbers in one block, which is the single biggest cause of buyers ordering the wrong corner. Fitment is by the number laser marked on your original sensor and by which axle it came off, not by the vehicle model name alone.
Left and right are not the same part. 2H0927807A and 2H0927808A are handed mirror parts. The moulded fixing arm and the cable exit are on opposite sides so that each sensor reaches its own harness clip without strain. Fitting a left sensor on the right corner will either leave the lead stretched across the brake hose or point the mounting arm away from its boss. Confirm the suffix A on the original unit: earlier catalogues also list the base numbers 2H0927807 and 2H0927808 without the suffix, and the A index is the version fitted to the production Amarok covered here. If your original sensor carries one of the ATE service numbers 24.0711-6251.3 or 24.0711-6252.3, or one of the cross references AS4856, AS4855, 84.1476, 84.1477, 116 165, 116 166, SS20035, SS20036, 23824, 23823, GBS2515 or GBS2516, it belongs to the same rear axle application.
Active sensor, no air gap adjustment. Because this is an active Hall sensor reading a magnetic encoder ring rather than a passive reluctor, there is no air gap to set with a feeler gauge and no toothed ring to clean. What does matter is that the sensor seats fully in a clean bore, that the O ring is sound so water cannot reach the encoder ring, and that the encoder ring on the wheel bearing is undamaged and fitted the right way round. A bearing installed backwards, or a cheap bearing with a weak magnetic ring, will give a plausible but noisy signal that no new sensor can fix. If a fault returns immediately after fitting a new sensor, check the bearing encoder ring and the two pin supply voltage before condemning the part.
Installation and diagnostic notes
Fitting. Work on a level lift with the ignition off and the parking brake released. Support the vehicle safely, remove the rear wheel, unplug the sensor connector and unclip the lead from its retaining points along the trailing arm before undoing the fixing bolt. Clean the mounting bore thoroughly, because grit or rust scale will hold the probe proud of its seat and change the signal. Lightly lubricate the new O ring, push the sensor fully home, tighten the bolt to the VW specified torque without overtightening the plastic arm, then route the lead exactly along the original clips so it cannot chafe on the brake hose or be stretched at full suspension travel. Reconnect the plug until it clicks. Repeat on the other side, then refit the wheels and torque them to specification.
After the mechanical work. Clear the ABS fault memory with ODIS, VCDS or an equivalent VW Group capable tool. Take a short road test with live data displayed for all four wheel speeds and confirm that both rear values rise and fall together from walking pace upwards, with no dropouts over bumps. Most Amarok ABS units will extinguish the warning lamps by themselves after a short drive once all four signals are plausible, but clearing the faults first avoids an old stored code being mistaken for a failed repair. If a steering angle or ESP basic setting was lost during diagnosis, perform the calibration as directed by the scan tool. Diagnostic and coding labour are the responsibility of the fitting workshop and are not covered by the parts warranty.
Physical specification. Active Hall wheel speed sensor pair for the rear axle of VW Amarok 2H, two pin D shaped connector, 12 V supply from the ABS control unit, moulded plastic body with a single bolt fixing arm, O ring sealed probe, approximately 42.5 mm sensor length and roughly 0.1 kg per sensor, so about 0.2 kg for the pair. Brand new, factory tested for output signal and insulation, supplied in protective packaging. Confirm the part number and the axle position on the original unit, or send us the VIN, before ordering.
Fitment
Fitment is by the number laser marked on the original sensor, the axle position and the engine code, not by the model name alone. This pair suits the rear axle only. Use this table as a guide and check your VIN or the old part before ordering:

Brand new genuine quality 2H0927807A and 2H0927808A ABS wheel speed sensors, twelve months warranty against manufacturing defects covering the units as supplied. The warranty does not cover damage from a corroded harness or connector, a contaminated or reversed wheel bearing encoder ring, an overtightened fixing bolt, a stretched or chafed lead caused by incorrect routing, or diagnostic labour. If a part arrives faulty, send us photographs and the ABS fault scan before returning anything.
Wholesale
Tiered pricing for 1 pair, 5 pairs and 20 pairs is shown below. Independent VAG workshops, pickup fleets and agricultural users usually order these sensors in pairs because both rear corners wear at the same rate and a matched pair removes the risk of a repeat failure on the opposite side. Ask for a combined quote if you also need the front axle sensors WHT003856 and WHT003857, rear wheel bearings with encoder rings, fixing bolts or ABS harness repair sections for the same job; we price mixed orders together and can hold stock for repeat workshop orders.
