I'll give that a go, but to be honest, I think it's something else. Even the lights on the window switches in the rear doors don't work.
I'm taking it to an auto electrical store today to see what they can do.
I'll be taking pics today, and most likely posting them with loads of questions!
My oil light has gone out now, I'm pretty sure the car has been standing for a long while, and I think it's starting to smooth out now. All filters and fluids will be changed today.
Thanks for all your comments, it makes me feel a lot 'safer' after buying this car!
All the best,
