You may not have noticed it before because it may not have been there before you took your car to servicing. I mentioned this offhand vaguely in another thread somewhere. But I noticed that this was added without documentation or mention by the dealership. And I know for FACT that it wasn’t there before because I just looked at the exact same spot looking for a way to route some wiring. Not sure if they’re supposed to do that but I assumed it fell under necessary lubrication. Still, they should notify with some sort of focumentation.
