A constant ABS light on your G11 usually points to a wheel speed sensor or its wiring. Here’s what to check first, likely causes, and whether you can keep driving safely.
Why the ABS Light Stays On in Your BMW 7 Series G11
When the ABS warning light stays lit continuously on your G11, the system has detected a fault and disabled itself. In most cases, the culprit is a wheel speed sensor – either dirty, damaged, or with a broken wire. These sensors sit behind each wheel hub and tell the ABS/DSC module how fast each wheel is turning. A single bad sensor is enough to keep the light on.
