Full Product Manual

ECM monitors driving style and selects a suitable time to employ regeneration.

Cars driven a lot at idling speed and low load will attempt to regenerate earlier

than cars driven more with high load and high 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, 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.
