What this usually means
A7 MMI faults can be battery voltage, software, fibre loop or module fault before full headunit replacement. Ask for ODIS scan and battery test first.
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: ODIS
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
