Currently got an issue with BCU on disco 2.
I took the car out last week and had no indicators, reverse lights, wiper function when washing the window, front windows, and central locking.
The following day I took the BCU out after doing some research and cleaned it up, had a little bit of corrosion and left it to dry.
When put back in it had flashing B with a / through it on the dash. I tried to code it with a hawkeye to no joy.
Since then I tried another BCU, just the same and it won’t even try to start the engine same as the other.
I have also now tried with a nanocom too and still the same flashing B error and no luck.
Also since re plugging either bcu in I’ve got central locking back.
nanocom is saying it has no communication with ecu when I try to sync it.
Any help or ideas?
