2011 X5 35d glow plug and engine coolant/transmission fluid thermostat replacement
 

I think I know the answer to this, but the dealer is telling me that reprogramming is required when replacing all of the glow plugs and control module. Hinted similar was required for engine coolant and transmission fluid thermostat replacement also. I don't buy it and never seen it done as part of the DIYs I've reviewed thus far.

No reprogramming just clear error codes
