Good morning colleagues,

i have a problem on a 2007 citroen c4 gran picasso 2.0 hdi 100 kw RHJ engine type with robotized gearbox.

The car, after taking a depression or a pothole, breaks down, the gearbox gets stuck in first, second and third gear, a communication error with the abs control unit is stored in the engine control unit, easy move invalid data U1219 is stored in the abs control unit.

after deletion of the errors, the gearbox starts working normally again.

These errors remain stored and can be deleted, while a non-erasable error remains on the body computer:

ENGINE FUSE BOX: MUTE ON CAN U3000.

Has anyone had to deal with this problem?

thank you in advance
