Hello C4 driver, just have trouble with my C4. Warning message “Airbag or belt strapper defective” which appears quite irregularly and disappears after a minute. Has anyone ever had this before?? Car was now 5 times in various contract workshops, each time over the Assitance, and nobody got it. At the moment the car is at the dealer’s reperatur. Doesn’t know yet what comes out of it. But what is even worse is the behavior of Citroen Germany. D he does not seem to be interested when their cars cause trouble. They don’t take care of their customers at least, but also point unkindly to your dealers and contract workshops. But quite honestly, if you turn to, if they don’t get it? Logoschweise after all to the manufacturer, or not?! You don’t know how it is with other manufacturers, but after the action: NEVER EVER A CITROEN!!!!!
