Information:
Adaptation of service intervals due to significant variations in fuel quality.
The service intervals for vehicles as of model year 2008 were adapted according to market-specific conditions due to considerable variations in the quality of the fuel available in the various markets. Model year 2007 vehicles manufactured from 20.03.2007 onwards were already coded with the adapted service intervals.
As a result, there is a difference between the "Service in km/days" and "Service now" message in the instrument cluster and the service interval details in the "Warranty & Maintenance" booklet for these vehicles in the markets specified above.
The message in the instrument cluster prompts the driver to have "Minor maintenance" performed for the first time after approx. 20,000 km (12,000 miles) or 1 year, while the "Warranty and Maintenance" booklet for model year 2007 vehicles specifies a service interval of 30,000 km (18,000 miles) or 2 years.
If the customer insists on having his/her vehicle serviced only when the service intervals specified in the "Warranty & Maintenance" booklet are reached, the service interval in the instrument cluster must be re-coded using the PIWIS Tester.
Affected Vehicles:
Model year 2007 vehicles manufactured between 20.03.2007 and 31.07.2007.
Tools:
PIWIS Tester 9718 with test software version 20.000/11/2007 (or higher) installed, Part No.000.721.971.WW.200
Battery charger (charging current at least 40 A).
Action Required:
Re-code the service interval in the instrument cluster.
- To do this, first reset the service interval using the PIWIS Tester. Then, code the distance travelled and the time since vehicle handover to the customer into the instrument cluster.
CAUTION
A fault is entered in the fault memory and control unit programming is aborted due to low voltage.
- Increased current draw during diagnosis or control unit programming can cause a drop in voltage, which can result in one or more fault entries and the abnormal termination of the programming process.
- Before commencing work, connect a suitable battery charger with a current rating of at least 40 A to the jump-start terminals in the engine compartment.
Work Procedure:
1 Connect the PIWIS Tester to the vehicle and switch it on.
2 Switch on ignition.
3 Call up the --> 'Diagnosis' menu and select vehicle type - 'Boxster (987)'.
4 Select 'Instrument cluster' in the --> 'Control units' menu and confirm by pressing >>.
5 Select 'Special function' in the --> 'Boxster (987) instrument cluster function selection' menu and confirm by pressing >>.
6 Select 'Reset service interval' in the --> 'Boxster (987) instrument cluster special function' menu and confirm by pressing >>.
7 Select the model year [MY < 08] and confirm your selection by pressing >> .
8 Select the unit for the distance [km] or [miles] and confirm your selection by pressing >>.
The service interval is reset and the following message appears: "Writing service interval, please wait...".
9 Once the service interval has been reset, the following message appears: "Service interval was written, press >> to continue" and "Function completed successfully".
Confirm the message by pressing >>.
INFORMATION:
After resetting the service interval, the distance travelled and the time since vehicle handover to the customer must be programmed into the instrument cluster so that the "Service in km/days" and "Service now" message in the instrument cluster corresponds to the details in the Warranty & Maintenance booklet - Continue with Step 10.
10 Press << to return to the --> 'Boxster (987) instrument cluster function selection' menu.
11 Select 'Control unit replacement' in the --> 'Boxster (987) instrument cluster function selection' menu and confirm by pressing >>.
12 Select 'Distance travelled since last inspection' in the --> 'Boxster (987) instrument cluster control unit replacement' menu and confirm by pressing >> .
13 The distance stored in the instrument cluster is displayed. Press >> to continue.
14 Check the stored distance and correct it if necessary.
The distance travelled must be entered again using the keypad.
To do this, first delete the dummy string of digits ("00000") shown in the appropriate field and enter the five-digit distance.
15 Code the distance you entered into the instrument cluster by pressing F8.
16 Once the distance has been programmed into the instrument cluster, the message "Value was written" appears.
Press >> to acknowledge the message.
The distance you entered is displayed again.
17 Press << to return to the --> 'Boxster (987) instrument cluster control unit replacement' menu.
18 Select 'Time (in days) since last inspection' in the - 'Boxster (987) instrument cluster control unit replacement' menu and confirm by pressing >> .
19 The time in days stored in the instrument cluster is displayed. Press >> to continue.
20 Enter the date on which the vehicle was handed over to the customer.
To do this, overwrite the default current date with the actual date of vehicle handover to the customer using the keypad.
21 Code the date you entered into the instrument cluster by pressing F8. The time in days is calculated automatically from the entered date.
22 Once the date has been coded into the instrument cluster, the message "Value was written" appears.
The calculated time in days is displayed.
23 Press << to return to the --> 'Control units' menu (list of control units).
24 Select 'Special functions' in the --> 'Control units' menu and confirm by pressing >>.
25 Select 'All fault memories' in the --> 'Boxster (987) special functions function selection' menu and confirm by pressing >>.
The fault memories of the control units are read out.
26 Once the fault memories of the control units have been read out, press >> to display the faults stored in the fault memories.
Fault memory entries that are caused by the coding in the instrument cluster (e.g. "Instrument cluster communication") can then be deleted.
If other faults are present, these must first be located and corrected.
27 Press << to return to the --> 'Boxster (987) special functions' menu.
28 Select 'Erase all fault memories' in the --> 'Boxster (987) special functions' menu and confirm by pressing >>.
