Vehicle Type:

Cayenne E-Hybrid (9YA / 9YB)

Model Year:

As of 2019 up to 2023

Concerns:

DME control unit

Information:

The message ‘E-Power not available’ is displayed in the instrument cluster. The entry ‘P103A00 –
Engine oil – fuel content too high’ is also stored in the fault memory of the DME control unit.
This is not a technical defect, but a protective function of the engine control system, which is responsible
for the unavailable E-function.

Cause:

If the vehicle is driven more frequently for short distances, fuel can accumulate in the engine oil. To
prevent or correct this complaint, the combustion engine must be run for longer periods.

Action:

•

Inform the customer about the potential causes of this behavior and its avoidance using the specific
language for TI 53/21. Observe the specific language under “2470 – Specific language for TI
53/21” in the information medium TI – Technical Information, Main Group 2 – Fuel supply.

Information
Also use the description in the Owner’s Manual regarding the vehicle’s system limits. In addition, inform
the customer that the oil can be regenerated by driving for 30 minutes at an engine oil and coolant
temperature of >50°C/ 122°F and then electric mode is available again.
•

If the communicated content in the specific language does not contribute to customer satisfaction,
document the greyed-out screen message and perform a one-off oil change including oil filter. Then
additionally program the DME control unit to reset the value for the mass of petrol and alcohol in the
oil and – if available – upload a new DME data status.

Do not interrupt programming and coding.
Once the control units have been programmed and
coded, you will be prompted to switch the ignition off
and then back on again after a certain waiting time.
Backup documentation of the new software versions
is then performed.
