Audi A6 Bose amplifier defect?

Repair at a fixed price of 202,30€ with 2 years warranty *

MMI Failure in the Audi A6 4F and Q7.

Possible symptoms:

  • Complete failure. All speakers are without function. The front screen only starts up for a few seconds and then goes dark again.
  • The device does not switch off, pulls approx. 900mA and discharges the battery after 1-2 days.
  • Sound is stopping at times.

The ring fracture diagnosis with the workshop tester results in a defective amplifier.

The connection of a so-called most bridge to the fiber optic plug of the amplifier causes the screen to function again and only the sound reproduction is missing.

The MOST bus based Bose 6000 DSP amplifier can be tested and repaired. 

The component protection does not become active during the repair. The device works after installation "plug and play".

If you are interested in a repair, please contact us via the form , then send the device together with the completed order form to the address indicated in the imprint.

The fixed repair price refers to a device that has not yet been opened and is thus in an original state.
Unsuccessful previous repair attempts usually result in more effort and thus in additional costs.

In addition, the fixed repair price is not valid for damage caused by oxidation, e.g. by an broken water hose at Avant.

* All prices are excluding shipping costs.
