Is it necessary to replace the fan clutch motor when replacing the water pump or is the service department trying to rip me off

I believe you are talking about the thermo fan clutch. There is no motor involved.
No, if it functioning good it does not necessary to replace with the water pump.
Did they tell you what's wrong it it?
I'd get a second opinion.....

I have many regular clients with over 100K miles in their BMWs with the original fan clutch and they are working perfectly fine. Some had a replacement water pump - since I don't like and don't trust pumps with plastic impellers, so they were replaced by one with metal ones, but still uses the original fan clutch.
I have seen failed clutches at 60-70 K, sometimes even at lower miles, but there is no regular replacement interval for those.
I have several BMW factory repair manual - I don't think I ever read about a 30K replacement interval, but I''ll check them tomorrow when I'll be at the shop.
