For any repair requested by the owner under warranty or outside warranty that requires update programming, which will automatically wipe out the
"Tuning" program, your Dealership should advise the owner of the above and get Owner's written consent (see Control Module Tuning form shown
above) to the update programming procedure.

Tip:

Before update programming, delete the fault memory in the ECM. Update programming is not possible when an EEPROM fault is active.

Reprogram ECM with CD - Part number W42200518TSWU.

^

Insert the programming CD into the VAS 5051 / 5052, and access the ECM.
