Touch screen computer not working - Mk 8 1L Eco Boost Fiesta

[Travisty]

Hi all

So my fiesta broke down on me a few weeks ago, which I believe is sorted now. I originally got advised to bring it to a ford dealership. They did a diag on the vehicle, and then the dealer wanted to collect the vehicle to fix it.

Since I have had it back the computer has not worked correctly. It freezes, lags, disconnects, crashes completely and jumps to random AM radio signals that just give me loud static.

I have tried many different things from, master reset, hard reset, manually updating and disconnecting the negative and both negative and positive from the battery (both for over an hour as I was also doing other things).

None of this seems to do anything, the only thing I have noticed is that I think its phone connection related. The system seems to run fine when I don't try connect a phone to it. I have tested it with a couple of phones, and it does have the issues with other phones too.

If anyone has any advice on this at all, it would be greatly appreciated because I am at a loss

Bring it back to the dealership, especially as the problem exists since their service.

Taking into account the above mentioned it should be done under "warranty".

Agreed, book it back in, they've buggered something up
