My 2013 C4 Picasso has suddenly developed a problem where ALL the warning messages seem to come one after another when starting the ignition.

Errors such as “parking brake issues”, “roll back”, “Driving aids”, “ABS” etc etc etc, all accompanied with the annoying beep.

The car runs absolutely fine, and no warning messages have ever come up before, so am wondering if this could be an electrical short fault or something similair with the ECU but am wondering if anyone else has encountered a similar problem.

The only thing I can think is maybe the battery might be at fault and not providing enough to the ECU but haven’t had a chance to test yet.

All help or advice gladly received

Good chance it’s the battery.

Yep. Will check the battery when I get back home. The errors seem to come on even before firing up, just with the simple START press. Would it be more likely to be the battery if problems started when actually firing? Really not that sure and thanks again. P.
