Figure 7. Search Text / 89 Values.
Tip: It is only possible to receive the correct control unit if the diagnostic log was sent with the
relevant event memory entry, the completed test plan, and the 89 values shown in the Global
Variables.
8. If there are less than 89 values this TSB repair will not work, and it does not apply to the
vehicle. Repairs should be made outside this TSB according to ODIS test plans and the
repair manual.
9. Perform Guided Fault Finding for the relevant event memory entry and follow the instructions.
10. Answer ‘YES’ to the question “Could you locate relevant Technical Service Bulletin (TSB)” or “Could
you locate relevant Technical Product Information (TPI)?”
If the test plan requests a TSB or TPI number enter: 2058356
11. Continue with the test plan, and the following message will come up with important information you
need for parts ordering (Figure 8). Make note of the 4 letter index of the Mechatronic and compare it
to the parts list table in this TSB. If the index shown in the test plan is available in one of the parts list
below answer the test plan question with “Yes” if the 4 letter index of the Mechatronic is not shown
available in one of the parts list below answer the test plan question with “No” and this TSB doesn’t
apply to the vehicle.

12. If the index shown in the test plan is available in one of the parts lists below, and the test plan was
finished correctly, upload the GFF log to GFF paperless and order the correct parts from one of
the tables below. Read all notes in the parts information section of this TSB.
Tip: The immobilizer must be readapted after replacing the control unit. For this purpose, it is
essential that all vehicle keys are present at the time of the repair.
13. After receiving the required genuine parts, remove mechatronics unit from gearbox according to the
repair manual.
14. The sensors are on the back of the mechatronics unit and must not be touched/damaged. The

Technical Service Bulletin
• Touch a suitable earthed object (VAS 6613 ESD Work Surface) before working on
electrical components of mechatronic unit. Do not touch the contacts or electronic
components directly.

You must ensure the highest levels of cleanliness for all work on the mechatronic unit.
Even the smallest dirt particles or hairs in the system can lead to restricted functions and
ultimately to failure of the mechatronic unit.
15. After removing the mechatronic unit, place it in the assembly aid to protect the sensors. The
assembly aid comes with the new control unit. First take the control unit out of the assembly aid and
store it safely in the packaging. Place the mechatronic unit in the assembly aid (Figure 10) with
sensors facing downwards.
