Welcome to the forum Will, you'll find the members on here are a friendly and helpful bunch :)
My first question is the car petrol or diesel?
And where did the AA recover you to, home or a garage?
The 2.0 litre suffers from rear main crankshaft seal failure as well as pcv valve failure and there was a recall for this. Here's a YouTube video with regard to pcv:
The pcv controls the oil pressure and when it fails it can cause an increase in pressure and thus oil leaks.
But as I say we need to know your engine to help further.
Cheers :)
