At our Ulu Otomotiv shop in Kadosan, Ümraniye, we diagnose ABS faults based on computerized code reading, not guesswork. We pinpoint the real cause behind that illuminated ABS warning light (wheel speed sensor, wiring harness, ABS unit, or hydraulic pump) and only address the part that is actually faulty. With guaranteed workmanship and a transparent process, we restore your braking safety without replacing parts unnecessarily.
The ABS (anti-lock braking system) prevents the wheels from locking up under hard braking, helping you keep steering control of the vehicle. The system consists of wheel speed sensors at each wheel, tone rings (ABS rotors), an electronic control unit, and a hydraulic modulator pump. A fault in any one component triggers the ABS warning light on the dashboard. At Ulu Otomotiv, we start ABS repair with OBD computerized code reading rather than guessing at parts. We evaluate the fault code, live sensor data, and the wiring harness together to isolate the true source of the problem. Our service covers the entire process, from diagnosis to parts sourcing and installation, followed by a test drive and clearing the fault codes. Our goal is for your brakes to work flawlessly when it matters most.
If you notice any of the symptoms below, a prompt expert inspection is important.
A yellow ABS warning that does not go out when the ignition is turned on, or that comes on while driving, means the system has detected a fault and disabled itself. In this case your normal brakes still work, but the anti-lock protection is out of service.
If the wheels lock and the car skids when you brake hard on a slippery or wet surface, the ABS is not engaging. This is the most critical symptom of a sensor- or pump-related fault, and it lengthens your stopping distance.
When the ABS is working normally, you feel a slight pulsation in the pedal. If this feedback disappears completely during an emergency stop, or conversely you feel constant/unwarranted pulsation, it points to a wheel speed sensor or modulator fault.
The ABS, ESP, and ASR (traction control) all use the same wheel speed sensors. When these lights come on together, it usually traces back to a shared sensor or wiring fault, which we separate out with computerized diagnostics.
The ABS light flashing or throwing a fault as you slow down is usually caused by a wheel speed sensor that has become dirty or has the wrong air gap. With early intervention, this can be resolved without replacing the unit.
Damage around the sensor or tone ring can cause a rubbing or ticking noise while the wheel turns. These noises, combined with signal distortion, call for an inspection of the ABS rotor.

“On my Passat the ABS and ESP lights were on together, and another shop had recommended replacing the whole unit. Ulu Otomotiv hooked it up to the computer and showed me the problem was only the right front wheel speed sensor. Just that one sensor was replaced and the light went out. They saved me from an unnecessary expense.”
“When I noticed the car skidding under hard braking in the rain, I went to the shop in Ümraniye. They read the fault code, showed me the sensor signal in live data, and explained what they were doing as they went. On the road test I felt the ABS engage for myself. The transparent approach really inspired confidence.”
“At low speed my ABS light was flashing. I had assumed it was a unit failure, but they found the sensor and tone ring were dirty, and after cleaning and adjustment the problem was solved. Thank you for the guaranteed workmanship and honest diagnosis.”
