Oil Temp. Frustrations

Hello All, New Member here My '09 335i Xdrive w/sport pkg has gone into "limp" mode 3x's due to oil temp..it does NOT have an oil cooler I read in a post somewhere that BMW was/has retro fitted some with coolers, does anyone have any experience or knowledge about this? Cuz when I call USBMW 800# the Rep knew no such thing and told me to speak with my dealer.

3 Series xDrives with M Sport typically don't get the oil cooler. This is because the standard all weather tires aren't rated for the higher speed. Recently, you had to get the optional Performance tires to get the 135 MPH Speed Limiter removed -- which is what adds the oil cooler. I believe you can add the oil cooler, but it's several thousand dollars. My oil temp has never been high on my 2011 xDrive, but then I don't track my car. Maybe earlier models are more succeptible.

At the time of the 'limp' what was your oil temperature? What were the driving conditions? You should also check your coolant level because low coolant will raise oil temperatures.
It is very unusual for oil temperature to rise to limp mode under normal driving conditions, even in the desert.

The retrofit was for 2007 (and maybe 2008) sport-package-equipped non-xDrive cars with automatic transmissions. Subsequently, all sport-package non-xDrive cars and all sport-package-with-factory-performance-tires xDrive cars were given the oil cooler.

I have heard of no one with a 2009 having an oil cooler retrofit at BMW's cost.

Yup. My non-oil-cooler car didn't go above 240 degrees on a 106F day running at 80 - 85 mph. Highest I've ever seen is 250F, chasing DSX up Mt. Washington in 2nd gear two years ago.

The question: Was your oil really that hot? Unheard of in normal use. Poss bad sensor or wiring - should verify oil temp sys within spec.

There are a couple o'sensors at work here:
The first has a thermistor to determine oil temp. The second determines oil level based on thermal transfer from sensor to oil - mass transfer if you will.

'Yer nuts, Waterboy!", you say. I direct your attention HERE and, if the the truth be known, there are three sensors, capacitive actually having the capacitive tube and thermistor, two sensors in one package.

Or, the thermal oil level sensor was ended with the E46. Dunno. Can't find it on N54. I might be nuts. Unlikely to be referring to the plug-in RTD/Thermistor in the capacitive probe as that alone would not be able to read oil level. I'll fall back to delusional, a great relief.

Have no info on whether both can cause an error - prob though. Thus, you really, really need to read codes w/GT1 or BT. Then experience and interpretation will resolve.

How's your oil pressure?

What codes did your car log?

You can always install the oil cooler. That is what I did using only BWM parts and dealer installed. However I do agree with everyone above it seems very unusal to be getting a limp mode which typically kicks in at 270F.
I think checking the sensors and what they are reporting is certainly in order.
I have seen 270F in Europe but nothing over in the US I have yet to see over 260F.

Thank you all for the info and in reply to some, I was driving quite spiritedly at all times. I do recall the temps jumping very quickly and reaching somewhere in the range of 270ish. Therefore I have scheduled a visit with my dealer to investigate all sensors as Fun2Drive suggested. Yes sounds like the common sense thing to do, my oversite indeed. Thanks again to all!! Wishing you all the same fun I have with mine...Be safe!
