‒
If the event entry U300100 is logged under diagnostic address 0002, continue with the next point.
•
Using the⇒ Guided Fault Findingcheck whether event entries on the system voltage (low voltage) are logged in at least 3 further control units:
‒
If event entries on system voltage (low voltage) are logged in at least 3 further control units, then these event entries must first be completed according to the⇒ Guided Fault Finding. Then continue with the next point.
•
Using the⇒ Guided Fault Findingcheck the voltage supply and the fuse of the mechatronic unit for dual clutch gearbox (-J743-).
‒
If the result of the Guided Fault Finding is incorrect, then it must be repaired according to the⇒ Guided Fault Finding.
‒
If the result of the guided Fault Finding is correct, continue with the next point.

For the simplified processing of the warranty accounting on the manufacturer side the TPI number must also always be included. In markets with DISS/SAGA coupling the TPI number is automatically used from the DISS system. In markets without DISS-SAGA coupling the “HST transaction number” field must be manually populated with the TPI number.
The labour times are correct at the time of publication. The time units may differ, if the repair operations catalogue has been updated. In this case the time allowances in the repair operations list apply. The open time items (...99) that are entered manually are exempt from this.The necessary time for using the ODIS tester is not included. The time must be accounted separately via the diagnostic log of the ODIS tester.The repair operation 001500 A8 for accounting the labour from the diagnosis log is created by APOS NF on the system side and automatically added to the shopping basket.
