Right side hose, the cooled side just as it attaches to the throttle housing. The left side is the hot side from the turbo into the "noise muffler" before the intercooler.

No code, although many of the threads I've read got to that point, and no whistling either, however, others have also reported that as well.

Stench of oil smell, which I hate with a hot hate, especially in the garage. I notice it about a week ago, and it was getting worse. my 642s are bone dry and clean, so when the oil smell comes, I know something's been breached. (I change the turbo and breather seal once a year, never a drop of oil in the valley)

I had oil on the back side of the corner of the radiator area on the right, and the right air inlet had a fine oil coating on it as well, investigated further to find more oil coating on normally dry parts. Squeezed hose and saw splits.
