Smoking Engine Bay

I checked mine the auxiliary belt drives the alternator, Aircon compressor and a water pump.
This is not the main engine cooling pump it’s a pump to cool the electronics and alternator, any smoke could easily be from this belt, maybe a seized pump, tensioner or even alternator.

I'll get the full report on Tuesday with detail but it's something to do with the slipping of the camshaft belt. I could pretty much see it moving, rubbing and creating the friction and smoke at higher revs with the hood open.
