All interior lights and door lights stopped working in my Sharan 1.9 TDi (Nov 01 New Shape)

Hi, All my interior lights including the visor lights and door puddle lights have stopped working in my VW Sharan 1.9 TDi (Nov 2001 New Shape). I have found the fuses under the steering wheel with the help of the User Manual and all relevant ones look OK. What else can I do? Is there an electrical control unit or module I should change and if so, where is it located? Perhaps there are some hidden in-line fuses or perhaps some relevant fuses inside the engine compartment? If one interior bulb blows, do they all stop working - surely not?

I should add that the central locking is working OK.

Thanks in advance.
