00BC rear passenger side) using the SVM action code as listed in the table below, if necessary.
Tip: Parts indicated below with an *, additionally in the replacement reference, require part replacement
prior to performing SVM (A7 and A8 only).
3. After replacing the required parts (A7 and A8), continue with SVM update.
4. Perform basic settings of all four windows.
