Quick backstory - About a year and a half ago I purchased a neglected 2015 GT3-R. After replacing the Battery the MMI would continually "reboot". I took it to the Bentley dealer and they told me the MMI was broken. I managed to find a working unit and had it replaced and everything seemed to be working.

Fast forward to today, the car came out of winter storage and everything seemed ok. However, in the last couple of weeks the MMI is back to the reboot cycle.

Could the replacement have also failed? This seems suspicious since that would be two failed units in one car. What an I missing? Could something be killing the units? Or could it be something else?

I am going to sell the car and I don't want to sell it with a broken MMI. I also don't want to give the dealer $10K to "fix it", especially if it will fail in the future.

Any help would be greatly appreciated.

Thanks,

Roger

 

I took the car to an independent shop to have a service. They took a look at the radio and said "it's broken" (as suspected). So that's two broken radios in a year. I guess I need to take it to the dealer and spend 10K on a new on and some more advanced diagnostics to figure it out. Disappointing outcome.

Anybody have any ideas on what I should tell the mechanic/dealer? As there diagnostics for the MMI specifically? Could I get ahold of the diags and run them myself?

Thanks,

Roger
