In the event of the car being driven in such a way that regeneration is not possible, i.e.
frequent short journeys, a diagnostic trouble code will eventually be registered, DPF light
and “Check Engine” indicator comes on. A service regeneration can be requested in the
workshop, using the diagnostic tool.
Before carrying out a forced DPF regeneration using the tool, check the following items:
The fuel light is not on.
No DPF-relevant faults stored in system.
The vehicle has the correct spec engine oil.
The oil for diesel is not contaminated.
IMPORTANT
Before diagnosing a problem vehicle and attempting to perform an emergency
regeneration, it is important to obtain a full diagnostic log and read out relevant measured
value blocks.
NOTE
1. The DPF will not regenerate if the engine management light is on, or there is a faulty
EGR valve.
2. The ECU must be re-adapted when replacing the DPF and when topping up the fuel
additive Eolys.
3. If the vehicle needs to be driven in order to perform a DPF service, ALWAYS have
a second person help you. One person should drive the vehicle while the other
person observes the screen on the Tool. Trying to drive and observe the Scan Tool
at the same time is dangerous, and could cause a serious traffic accident.
Steering Angle Sensor (SAS) Service
Steering Angle Sensor Calibration permanently stores the current steering wheel position
as the straight-ahead position in the steering angle sensor EEPROM. Therefore, the front
wheels and the steering wheel must be set exactly to the straight-ahead position before
calibration. In addition, the vehicle identification number is also read from the instrument
cluster and stored permanently in the steering angle sensor EEPROM. On successful
completion of calibration, the steering angle sensor fault memory is automatically cleared.
Calibration must always be carried out after the following operations:
Steering wheel replacement
Steering angle sensor replacement
