The Engine was leaking oil, so were trying to change the Crank Shaft Seal, as the mechanic was doing something to be able to open the bolt, I have seen and electrical contact sort of elektrical spark from the cables ( not sure but I think so), then when we run the engine the Fuel Gauge was not working at all and the Airbag light came up. Could it be the cable, or fuses? Everything was working fine before.
Can somebody help me urgently? Very much appriciated!
