What this usually means
PDK jerking can be fluid/adaptation, mounts, or mechatronic-related before gearbox replacement. Ask for PIWIS fault codes and adaptation values first. A full gearbox quote without PIWIS diagnosis is weak.
What to ask the workshop before approving repair
- • Show the diagnostic fault codes.
- • Show photo/video proof of the failed part.
- • Give an itemised quote for parts and labour.
- • Explain why cheaper common fixes were ruled out.
- • Use/confirm: PIWIS
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
