Hi,
I've got a C4 Picasso 1.6 HDi BMP 2008. Every time I power it up it displays "PARKING BRAKE FAULTY" and after a while "ESP / ASR FAULTY". Still everything works except for the automatic parking brake application and the service light is illuminated.
The only fault code that the ESP has is "ESP8.1 No communications with the engine management ECU Data invalid - Temporary - U1208".
It always shows up immediately even if erased with Lexia. It happens even with "key on engine off" so I guess it is not a matter of voltage dip during cranking. I have reset the BSI several times to no avail. Any clues?
