i have a strange problem with fiat ducato van 2016. after driving for a while you hear a sound of valves rattling, usually it starts to smoke blue then. if you then give full throttle you will get a shock if or for 1 second full on the brakes. noise is gone, smoke is gone. then get a message that esp and hill holder is not available. cruise control is disabled but available. the car then drives completely normally for 5 minutes to several days. and then everything happens again.
