electrical faults

[yellow182jon]

bought my car on saturday and knew the service light was on but need help with the following...


the airbag light turns on every so often,atleast once everytime i go out then turns off,

the car drives fine for while then the electrical fault light comes on and it goes into limp mode intill i turn ignition off then its fine again,

last thing is the sppedo works fine 90% of time then all of a sudden it tunrs off so messes all the say mpg etc readings,

would this all be loose connections or does this sound more seriuos, shall i just book it in with renault
