Technical multipla 1.6 16v engine s/n and type: where are they?

[eolonano]

Hello guys,

I'm looking for an used CNG Multi (not too old, between 2007 and 2010).
Do you know where I can find the engine serial number and the engine type on the engine block?

(I now that up there in Uk you don't have the cng version but I think that the info I need have been stamped in the same spot for the petrol version.....)

Thanks!!
