Ghost Wipers

This bulletin applies to BMW models 2-Series, 3-Series, 4-Series , M3, M2 and M4 produced from march 1, 2015. The windshield wipers may intermittently switch on by themselves and can no longer be switched off despite action of the switch.

An internal software error in the SZL (steering column switch cluster) may be the cause. BMW recommends replacing the SZL. Note that the SZL does not require programming after replacement.
