Flexible Service Intervals Opel Corsa C

From model year 2004 (Z 10 XEP only), on the Opel Corsa-C engine oil condition monitoring (oil life monitoring OLM) is being used. The monitoring function is performed by the engine control unit (ECM) and instrument cluster.

Replacement of Engine Control Unit (ECM) or Instrument Cluster

The engine control units supplied for Service are not programmed.

Factory Programming

Ecoservice-Flex Is Programmed in the Factory (Service Plan/checklist "O"). the Corsa-C Has Its Own Checklist, Service Plan "O".

Ecoservice-Flex

The new Corsa-C has a flexible engine oil change interval depending on the customer's driving profile. Under optimum conditions, 2 years/34,000 km can be achieved with a petrol engine or 2 years/50,000 km with a diesel engine.

An algorithm determines this from the information:

• Distance covered
• Engine speed
• Engine torque
• Drive cycles
• Coolant temperature
• Oil temperature

the driver's driving habits, and from this determines the distance remaining to the next oil change.

The length of service interval is not affected by adding engine oil of the approved quality.

Instrument Display

The customer is informed of the next necessary engine oil change by a display in the trip meter.

The need for engine oil change divided into:

• "Remaining mileage between 500 - 1,500 km" (1) or
• "Remaining mileage less than 500 km" (2)

is displayed automatically in the instrument panel trip meter for a few seconds every time the ignition is turned on. In the range 500 - 1500 km a fixed value of 1000 km is shown, and in the range 0 - 500 km a fixed value of 0 km.

Retrieve Remaining Mileage

Another possible display is "Remaining mileage until next Service". This is option is activated when the ignition is switched off by pressing the reset button of the "Trip odometer" in the instrument panel. The remaining mileage will be displayed in the odometer in 1,000 km increments.

In the worst case, under difficult operating conditions, the reminder for the next service engine oil interval will appear after just 15 months. If the battery is disconnected, all engine oil service interval data are stored in the EEPROM and still available after battery reconnection. A driver with an average driving profile covers around 15,000 km per year, a little use driver covers less than 5000 km and a short-distance driver has frequent cold starts and is comparable to a little use driver. Little use drivers and short-distance drivers will be reminded of the engine oil service interval at the earliest after 15 months. With the ECOService-Flex on a petrol engine, the little use driver or short-distance driver will have covered 6,800 km after 15 months.

The Opel Corsa-C is supplied with different engine oils allocated to the engines listed below:

Add Engine Oil

As an exception, the customer can use engine oil of grade ACEA-A3 or ACEA-A3/B3. Ideally, the viscosity of the engine oil used should then be 0W-30, 5-W-30 or higher than 30. Use of 10W-30, however, is still possible.

If the vehicle has been topped up with more than 1l engine oil of grade ACEA-A3 or ACEA-A3/B3 within one engine oil change interval of two years, the ECOService-Flex interval (Service Plan/Checklist "O") no longer applies. Service Plan/Checklist "G" is to be used instead.

Ecoservice

During the first Service, it may be necessary to program ECOService (Checklist "G") due to individual driving styles, e.g. high-mileage drivers with petrol engines. In conjunction with this, use of another engine oil grade is possible: ACEA-A3/B3. The instrument panel and control unit must then be programmed for ECOService - this is also necessary after an engine oil change if the customer wishes to continue in ECOService mode, since ECOService-Flex is programmed automatically upon reset. Upon each Service of Service Plan/Checklist "O" and "G" ask if the current Service Plan is to be retained. For Service Plan/Checklist "O", Corsa-C has interval

Reprogramming is performed via instrument assembly programming. When reprogramming has been performed, it must be recorded in the confirmation fields of the Service Booklet ("Engine control unit/instrument reprogrammed"), and there is also a sticker/label for the engine compartment that indicates the change. This sticker/label is also required if the engine control unit has been replaced. After an engine oil change, the flexible service interval is reset by the service technician.

Example for Completing the Service Sticker

If the ECM is replaced, an extra oil change or an engine repair performed, the service sticker must be completed.

In this period, the service interval display is not decisive.

The scheduled service interval according to ECOService or ECOService-Flex only begins again when the service event recorded on the sticker is reached after an ECM replacement.

Reset Flexible Service Interval (Ecoservice-Flex)

The display for the flexible service interval (time and mileage) can be reset via the instrument cluster. The engine control unit is connected to the instrument cluster.

Manual Reset

• Ignition OFF. The speedometer display must show the trip odometer reading.
• Press and hold reset button (trip odometer button).
• Ignition ON and wait until the service interval display changes, holding the reset button pressed.
• After a few seconds, the speedometer display shows the symbol with maximum distance 34,000 km for petrol engine.

The time counter in the instrument assembly is set to 24 months. The engine control unit receives a signal via the CAN bus and the "oil condition" is set to 100%. The engine control unit and instrument assembly are thereby reset.

Point out to the customer also that a service display which has been accidentally reset by the customer cannot be corrected by the Opel dealer, especially when there is no service booklet. Depending on the distance covered since the last oil change/inspection, a new engine oil change may be required to avoid engine damage.

Reset the Service Interval with Tech 2 (Simultaneous Reprogramming of Ecoservice)

After an engine oil change, the remaining mileage display on vehicles with "ECOService" must be reset using TECH 2.

It is also possible to reset the remaining mileage display on vehicles with "ECOService-Flex" using TECH 2 . This should not, however, be done during a routine engine oil change for reasons of cost. The trip odometer button should be used for resetting for routine oil changes.
