This bulletin applies to BMW vehicles produced from March 1, 2015, to June 2019. This includes 2 Series, 3 Series and 4 Series vehicles.
The windshield wipers may switch on by themselves and can no longer be switched off despite activation of the switch, due to an internal software error in the SZL (steering column switch cluster).
The correction involves replacement of the SZL. The SZL does not require programming/coding after replacement.
