'13 X5 6000 miles - Oil leaking under passenger side ?

So I looked under the engine chassis to see why I have small pools of appears to be engine oil on the driveway this past weekend and found some oil is dripping from the front passenger side of the car. Oil is all over the passenger side underbody with small drips from many places.

Took some pictures but can't really tell where the oil is coming from - nothing visible from the top. Should I look elsewhere ?

I made an appointment with my dealer and will let you know.

I hope it's not a turbo leak issue that some E70 owners have had to deal with

Using the on board engine oil level display - it went from full to 2/3 in one month - is that significant ?

Yes it is likely the red charge hose going from the turbo to the intercooler: mine is always coated with a film of oil, but since I wash the engine every time I wash the car it doesn't build up to point of dripping, but I can see that happening.

Oil is generally not from the turbo, but from the CCV. Since I installed the ProVent in my car I measure 4oz of oil filtered out of the blow-by every 1000 miles; all that oil would have otherwise gone through the turbo, the intercooler and the intake.

Ok, the X has been in the dealer service shop for 3 days now and each time they call me, they tell me a different issue.

Day 2: The leaky seals (turbo & coolant) have been fixed.

Day 3: Now they are telling me the DME is throwing fault codes and need to diagnose. Apparently a CEL came on while they were test driving after the leaky seals were replaced....

Never did have a CEL when I drove it - I hope they didn't break anything...

Today let's see what they say is wrong today...

I was under the impression that seals are often integral of the part for power train. I don't believe seals are places by itself but rather the part that contain the seal gets replaced. Am I wrong on this?
