Engine number

Firstly I have searched without sufficient result but I'm looking to locate the engine number on a 2006 scenic 1.5 DCI.

I've read that it maybe below the dip stick, under the cam belt cover or above the tdc sensor on the engine block....



I can't find it below dip stick or above tdc sensor. Don't have the capability to go digging around cam belt.



Help please ***128513;
