p1349 and oil light on extol

Forum: 

Hello all,
Just brought a extol van, 2004, petrol 1300cc.
Driving home 30 mins into my journey, the oil light came on.
Toped up oil, and the light momentarily went out.
however 1 minute later it appeared again, with the engine manegment light (MIL).

The code is p1349...
can anyone help point me in the right direction of whats wrong?

many thanks Archie
