driven more with higher load and speed. In order for regeneration to take place, a
prolonged high exhaust temperature must be obtained.
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 in
addition to the DPF light and “Check Engine” indicators displaying. A service
regeneration can be requested in the workshop using the diagnostic tool.
Before performing a forced DPF regeneration using the tool, check the following items:
⚫
The fuel light is not on.
⚫
No DPF-relevant faults are stored in system.
⚫
The vehicle has the specified engine oil.
⚫
The oil for diesel is not contaminated.
IMPORTANT
Before diagnosing a problematic 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, a second person
is needed for the function. One person should drive the vehicle while the other
person observes the screen on the Tool. Do not attempt to drive and observe the
scan tool at the same time. This is dangerous and puts your life and the lives of
other motors and pedestrians at risk.
5.7 Immobilizer (IMMO) Service
An immobilizer is an anti-theft mechanism that prevents an automobile’s engine from
starting unless the correct ignition key or other device is present. This device prevents
thieves from starting the car by a method known as hot wiring. Most new vehicles have
an immobilizer as standard equipment. An important advantage of this system is that it
doesn’t require the car owner to activate it; it operates automatically. An immobilizer is
considered as providing much more effective anti-theft protection than an audible alarm
alone; many auto insurance companies offer lower rates for vehicles that are equipped
with an immobilizer.
As an anti-theft device, an immobilizer disables one of the systems needed to start a
car's engine, usually the fuel supply or the ignition. This is accomplished by radio
