Electrical fault?

Having a day off work today as my Skoda Roomster Scout (2008, 1.4tdi) is showing several faults. Firstly I couldn't get into the boot, locked car and unlocked it using key and fob, it will not open. Got into car in heavy rain and the front wipers don't work, rear wiper working normally. Dash has airbag and traction control system warning lights illuminated permanently. I haven't been able to go anywhere as the rain is persistent so I've been trying to figure out if I can cure the problem with fuses? I don't have vag-com here and can't take her to a garage. Any advice appreciated, thanks.
