2012 Bentley GTC replaced both batteries main and starter and now I got all kinds of fault codes (ABS, traction, gear fault, cruise control, brake light and low battery light) I can't use the windows or top. Power seats work but not all the buttons like the neck warmers. Tried driving the car to reset and nothing, also check every fuse possible and they all seem to be ok. I am completely stuck anyone have any ideas?

Thank you

 

Did you install the batteries using the correct procedure ?

 

Take the negative terminal off the LHS big bat and leave overnight.
Refit in the morning and go for a drive . This should reset the dash lights .
Then adjust the seats and windows in the usual way ......after a battery hard re set .
