Hi just new to forum so apologies if I’m in the wrong bit. Looking for bit of advice. My daughters car dash has airbag, seatbelt, warning lights stuck on, stop/start light is stuck on and doesn’t function and the mileage is flashing. Quick search and am I right in thinking this is a common fault . I’m booked into fiat garage next week but is there anything I can try and find myself the thought of a big garage bill is giving me the fear I am being charged £114 just for diagnostics . I’ve tried a new battery but nothing else thanks
