Fault code
135302 - P10E0

Fault text
Valvetronic, component protection, servomotor:
deactivation, system

Fault description
The diagnostic function monitors the temperature of the
Valvetronic actuator motor.

Condition for fault identification
Test condition:
The fault is recognized when the calculated temperature of
the Valvetronic actuator motor rises above 200 °C / 65535
(temperature in the windings of the Valvetronic servo
motor).
Potential problem source(s):
- Valvetronic system consumes excessive energy owing to:
- Stiction and high resistance in the Valvetronic system
- Abuse ("blipping" the accelerator pedal, etc.)
- Frequent open-loop operation (limp-home mode/learning
routines)
Terminal condition: Terminal 15
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- None
Time condition:
- None
Other conditions:
- none

Condition for fault memory entry
none

Action in service
- Check electrical system voltage
- If other diagnostic fault codes related to Valvetronic are
logged, work through these first
- Check Valvetronic mechanism for freedom of movement,
wear and stiction (with external voltage source connected as
required)
- Replace components with mechanical wear

Fault effect and breakdown warning
Breakdown notice:
VVT system component protection
Possible apparent symptoms:
Range from no effects to power reduction/breakdown
