Gear Selection Release While Driving and White Message “Paddle Emergency Operation” On the
Instrument Cluster / Fault Memory Entries “U010300” and “B19DFF0” (62/25)

3

Model Line:

Cayenne (9YA / 9YB)

Model Year:

As of 2024 up to 2025

Concerns:

Gear shift mounting

Cause:

The customer is complaining about a white message on the instrument cluster “Paddle emergency
operation”, and the drive stages “P” and “R” cannot be engaged.
The following fault memory entry is stored in the fault memory of the transmission electronics (Tiptronic)
control unit:
•

U010300 – Selector lever, no communication (006B89)

In addition, the following fault memory entry is stored in the fault memory in the instrument cluster control
unit:
•

B19DFF0 – Display of shift paddle fault, active (EA663E)

After an ignition change, the complaint is no longer present for the time being, but it may recur.
Cause:

In rare cases, faulty software in the gear shift mounting control unit can interrupt communication to the
transmission electronics (Tiptronic). The transmission electronics reacts with the error “U010300” and
switches to temporary emergency mode.

Action:

In the event of a customer complaint, re-program the gear selector mounting control unit using the PIWIS
Tester.
