30D engine problems (2015)

Forum,
I got an X4 F26 30D 2015 (same engine as in X5) hense why this forum as it has more trafic.
Car just passed 110.000 km - no issues so far.
But today a slight whining (?) sound start to come from engine bay, and when left the car I noted a smell of hot rubber/plastic.
Opened the hood and tried to rev the engine - with higher rpm (around 3000) the whining is louder - car seems to pull all right
Anyone experienced similar with the 30D engine?
Suggestions to what it can be?
Water pump?
Belts?
Turbo?
?

Thanks in advance
JensM

Sounds like belt is loose or needs replacement?

I suspect a belt. Inspect them first, look for cracking, signs of burning, frayed edges.

You'll be unhappy if the belt is near the end of its lifespan and it breaks while you are out driving...
