Hi all, I have a 2021 3008 1.5 130 and arrived home and switched off engine to remove shopping from boot then realised my wipers on front were going every 5 seconds so I started it and the dash showed seat belt tentioners /air bag fault so I parked in garage not able to turn wipers off (the stalk switch did nothing not even spray water) so I had to resort to disconecting the battery

Any ideas before I take it to dealer.
Cheers and happy new year
