Hello together, I drive a Citroen C4 Picasso 1.6hdi Bj07. Wars again and again the error message esp abs and electronic hand brake is defect. I listened to others and changed the brake light switch, did nothing. Clutch switch (the white blue on the clutch pedal) changed also did nothing. See if there is a cable break on the battery up and in the fuse box. So slowly I am with my Latin in the end to be honest. What could I do? Thank you very much in advance.
