ABS & ESP Repair
ABS, ESP and BAS lights usually arrive together because they share the same wheel speed data. One sensor takes all three out.
Signs you need this
- ABS, ESP and BAS warning lights on together
- Speedometer dropping out or reading erratically
- ABS activating on dry roads at low speed
- Cruise control or lane assist disabled by a fault
How we approach it
We read live wheel speed values while the car rolls, which identifies a dropping sensor immediately — far more reliable than a static resistance check. Where the fault is the hydraulic unit or its control module, we handle the repair or replacement plus the SCN coding and bleed it requires. Corroded sensor rings on rear hubs, a common problem on coastal cars, are checked at the same time since a clean sensor reading a rusty ring still fails.
What the job includes
- 01Live wheel speed comparison while the vehicle is driven
- 02Wheel speed sensor and reluctor ring inspection
- 03Sensor replacement including seized sensor extraction
- 04ABS hydraulic unit and control module testing
- 05Module replacement with SCN coding and factory bleed
- 06Post-repair function test and warning light reset
Common questions
Is it safe to drive with the ESP light on?
The brakes still work, but stability control and often ABS are disabled — which matters most in exactly the emergency situations the systems exist for. Get it looked at promptly.
Why did three lights come on at once?
They share inputs. A single failed wheel speed sensor disables ABS, and ESP and BAS depend on ABS, so all three report a fault. One repair usually clears all of them.
