WLE3 Workshop campaign Replacing 12V vehicle electrical
system battery
Page 1 of 4
Version 1
Overview
Due to a manufacturing error, there is a possibility that the internal current sensor for the 12-volt vehicle
electrical system battery does not meet the required specifications on the affected vehicles. As a result, the
charge state will be calculated incorrectly and the 12-volt vehicle electrical system battery will then be
completely discharged when the vehicle is parked up for extended periods without an external power supply.
To prevent this from happening, the 12-volt vehicle electrical system battery (lithium-ion battery) must be
replaced.
Please arrange for this measure to be carried out on the affected vehicles during the next workshop visit or
before handing the vehicles over to customers.
