2014 X3 35i Oil Cooler?

Can anyone who has had a 2014 X3 35i delivered already tell me if your car came with an oil cooler? Especially looking for feedback from those with M Sport, but all feedback is welcome. Thanks!

would be very surprised if the X3 had an oil cooler.

I have seen pictures that suggest some do. Or, they did back in 2011. In the picture at the link below, you can clearly see the oil cooler behind the passenger side intake. I was thinking the oil cooler was installed because the X3 may be used for towing, not for tracking.

However, I am 99% sure the 2014 I saw on Saturday had a solid piece in that intake, just like on the driver's side, and I could not see an oil cooler through the grill in the passenger wheel well. I am just trying to get confirmation one way or the other.

I believe that all N55 engines have some sort of oil cooler. Quoting from an N55 manual:

Two different types of oil cooling systems are used depending on the model and application.
In the "hot climate" version, heat transfer from the engine oil to the engine coolant is
avoided by separating the oil cooler from the engine coolant circuit. The other version
uses an auxiliary radiator in combination with an oil to coolant heat exchanger bolted to
the oil filter housing. The auxiliary radiator enhances cooling efficiency by adding surface
area to the cooling system.

There are after-market oil coolers as well, mostly for racing.

My 2012 35i has one. I know for 2012 the 35i had them and the 28i did not, it was based on the engine.

Well, I think I have my answer. It appears BMW is no longer using a separate oil cooler and is now using an oil/water heat exchanger instead. In the picture below of the N55 in a '14 X3 35i posted by another member, you can see the exchanger on the filter housing. This is disappointing, but better than nothing, I suppose.
