The stability control light may also come on since it works with the ABS system to stabilize the vehicle by applying automatic braking to individual wheels. Therefore, when the ABS light is on, drive with extreme caution and fix the issue as soon as possible.
But in case of wet or snowy conditions, or when braking hard, you may lose steerability of the vehicle. What this means is, you can brake normally with moderate braking in dry conditions. The braking pressure from the master cylinder to the brake calipers is undiminished. When the ABS light illuminates in the instrument cluster of Z4, the ABS system is disabled and the braking system acts like older traditional braking system. If the fuse is blown, replace it with a new one with the specified amp rating.

Check the owners manual of your vehicle or the fuse box cover to find the exact location of the fuse for the ABS system. Blown fuse or bad relayĪ blown fuse or bad relay can cause the ABS system to stop functioning. When the ABS light comes on due to an underinflated tire, the low tire pressure warning light may also illuminate in vehicles equipped with TPMS (Tire Pressure Monitoring System).

When the speed difference between the wheels is detected by the control module, an ABS fault code is triggered for the speed sensor of the wheel with low tire pressure. The diameter of the wheel is reduced when its tire is underinflated, this causes the wheel to spin faster than other wheels in the vehicle. Low tire pressure in one of the wheels of BMW Z4 can cause the ABS light to turn on. ABS control units are fairly reliable and typically last at least 100,000 miles. Connect a diagnostic device to your vehicle to read the code. A malfunction in the ABS pump can cause the ABS light to illuminate in Z4, and a fault code is stored in the memory.
When you brake hard at high speed and the wheels lock, the hydraulic part of the unit actuates the valves to reduce hydraulic pressure to the brake at the affected wheels. The ABS pump, also called Hydraulic Control Unit (HCU), consists of an electronic and a mechanical-hydraulic part. Check the condition of the brake pads and rotors, also see if there is any sign of fluid leak under your vehicle and on the wheel hubs. The three common causes of low brake fluid are worn brake pads, worn rotors, and a leak in the system. But it is important to further investigate the reason for low brake fluid level. In case the brake fluid level is low, topping it off should turn off the ABS warning light in Z4.
