does the entire headlight assembly need to be replaced if the running light is out?

What running light ? Led stripe? Before facelift or facelift one?
Old version had led stripe they was powered from module on headlight facelift one have special module with led attached to it so you are just changing it...

The LED running lights are driven by external ballast units. I had a 2010 Q5 and one side died in 2011. Replaced under warranty.
