Addition of information to “Always replace the respective
components on the entire vehicle (left and right)”
Model Line:
Taycan (Y1A / Y1B)
Model Year:
As of 2020 up to 2021
Concerns:
Electric fan
Symptom:
Customers complain about droning or humming noise from the front end, even during the charging
process.
Cause:
This may be caused by foreign matter or dirt in the area of the electric fan and/or between the fan rotor
and fan frame.
Frequent driving on unpaved roads or roads with a gravel or grit surface or on sanded roads (winter) exacerbates the problem.
Remedial
Action:
A new component status of the electric fan (fan with frame and fan motor cap) as well as the air guides
and lower parts of the wheel housing liners is available immediately.
The new design has additional and larger foreign matter elimination openings on the underside as well as
a protective cap to prevent dirt and stones from entering the fan motor.
Information
Always replace the respective components on the entire vehicle (left and right) to the new component
version.
