The engine has the VW-Audi symbols cast into the head, so i'm happy it's a VW engine, but which one? Towards the bottom end are what look like the letters JD in the casing, whilst behind the injector pump is the serial 068 103373M and then further across 75 H. "WWO Germany" is also set in the casing.
A couple of photos may help with identification: -
