BMW E46 330D Not starting - Stuck in S Mode?

Hello all,

I'm having a really strange problem with a friends BMW E46 33D Steptronic,
The car refuses to crank, it switches on (All lights on dash).

On the Instrument cluster it shows "S" on the normal Gear selection (P R N D S M 1 2 3 4)

On the Centre Console (Next to Gear lever), The P light is illuminated, all the appropriate GEAR SELECTIONS are Illuminated if u shift from P right thru to D (Even dough the Cluster still displays "S" - NO CHANGE)

Did a diagnostic test on it with INPA and DIS. NO fault CODES at all.

I know that the autos WILL not CRANK if they are NOT in P or N
On the Transmission's Status it shows that the gear selection is in ???0??? (IN DIS) and M/S in (INPA)

Conclusion is that the car's electronics can's confirm in what gear it is, But what must be replaced? Gear selector unit itself? Checked all of the FUSES (Glove box and engine bay) - ALL FINE.

Thanks in advance
