Interior and ambient lighting

[copy40]

Hi everybody I've just purchased a a D4 4.2 TDI 2010 but it does have an issue with the ambient lighting and interior lighting as none of that seems to work even though it's selected in the menu fuses seem intact etc etc footwell lights work which is a bit strange I've had the centre ceiling console off to check wiring and everything seems to be ok, the only thing that has been fitted is a dash cam but that was done by a professional not the previous owner, a Google searches lead me to believe that the ambient/interior lighting is controlled by a module does anybody know where this module is? thanks in advance

I'd recommend a diagnostic check first to see if any fault codes flag up
