Fault text
Valvetronic system: no movement detected

Fault description
The diagnostic function determines whether the Valvetronic
system moves freely and without resistance during the
initialization routine.

Condition for fault identification
Test condition:
The fault is recognized when neither upward nor downward
motion of 6� is possible during initialization of the
Valvetronic system.
Potential problem source(s):
- Defective wiring harness
- Valvetronic actuator defective
- Valvetronic system sticking
- Defective DME
Terminal condition: Terminal 15
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- Engine warmed to normal temp, above 80 °C
Time condition:
- None
Other conditions:
- When the Valvetronic system is initialized (Terminal
15/Wake-up)

Condition for fault memory entry
none

Action in service
- Check wiring harness and plug connectors for electrical
faults
- 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 Valvetronic actuator motor
- Replace components with mechanical wear
- Replace DME

Fault effect and breakdown warning
Breakdown notice:
None
Possible apparent symptoms:
Once the VVT has reached its emergency running position,
unlimited throttled operation is possible.
If it fails to reach the emergency running position, results
ranging from a power loss to breakdown vehicle can occur
depending on the VVT position that the system does reach.
