Fault code
135401 - P10E7

Fault text
Valvetronic, overload protection: output stage overloaded

Fault description
The diagnostic function monitors the temperature of the
driver circuit.

Condition for fault identification
Test condition:
The fault is recognized when the calculated driver circuit
temperature rises above 120 °C.
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:
The engine runs in throttled mode, full drivability/power
Possible apparent symptoms:
VVT reverts to limp-home mode, minor effects can be felt

Driver information
Warning light:
- ECE emissions warning lamp: off
- ECE electronic engine power reduction: off
- CC message: none
- US emissions warning lamp: off
- US electronic engine power reduction: off
- CC message: none

Service instruction
None
