White smoke in Cabin, Smells like Candle-wax

Hey guys,

I was driving my car today and after about 15 minutes of driving, I parked up and measured the oil (it’s at minimum currently. Measured 5 days ago and it was about half)

About 30 seconds after measuring the oil, The cabin started smelling like candle wax. I had the climate control on low, and in the sunlight I could also see grey/white smoke coming out of the vents on the passenger side (didn’t really look at the other vents).

I drove the car around the block and it went away. This has happened once before, but I did t notice any smoke last time it was only the smell, no smoke.

Currently running: full bolt on with MHD tune, catless dp, er chargepipe, intake and MHD stage 2+).

Any thoughts as to the cause and where I should start checking?

I'd check the valve cover gasket first.

+1 for the valve cover gasket. What mileage are you at? Mine went around 63k but I only had a minor leak that the idrive oil sensor couldn't detect a leak.
