What's the BMW fault code a0b5?

If You're getting an A0B5 fault code on Your BMW's diagnostics, You're not alone; this is a fairly common anti-lock brake system trouble code. Fortunately, it should be a fairly simple fix. In the meantime, nothing about it is catastrophic, so just try to get it addressed at Your earliest convenience. A0B5 indicates that Your have a fault with Your wheel speed sensor. Specifically, my information is telling me that it's Your rear-right wheel speed sensor, though You should double check this with Your own onboard diagnostics. The most common reason for failure is a faulty wheel speed sensor itself, but it can also be caused by a defective wiring harness or a deteriorated tone wheel.
