Hey Everyone,

First post here on the E90Post as I just purchased my first ever BMW last week .

I bought an automatic 2007 E90 335i with 72K miles. The car has the Sport and Premium package. Since my purchase, I've been doing quite a bit of research on the vehicle as well as the recommended maintenance I should be looking into at these miles. (I will be buying a transmission oil change kit soon and servicing the transmission myself)

As with every used car I buy, I took it straight to the local BMW dealership to have them do a oil change, as well as an inspection. When it was done they informed me that it appears I have a small oil leak coming from both the valve cover gasket and possibly the oil filter housing gasket too. I did some searching on YouTube and located some great videos showing the step by step process of both of those repairs, so I believe I will be getting to that in the next few weeks.

The main purpose of my post is the part about not having an oil cooler. Come to find out, apparently at the beginning of the production in 2007, BMW forgot to add the oil cooler to cars being produced with the Sport package. With my car being produced in 02/2007, it appears it was apart of the "lucky" ones with the sport package that did not get the oil cooler .

After some searching, I found some people mentioning that BMW may have permitted that some of those vehicles have an oil cooler retrofitted after the fact. I was wondering if anyone has had any experience or luck with this issue? I am contacting both my local dealership and BMW on Monday to see if they would still be willing to perform the retrofit.

Any and every bit of help/advice is greatly appreciated!

Yes. BMW retrofitted my car back in 2007 and it was a 9/2006 build. I went to the dealership and had them print off my options list for my car. I then pushed back on BMW based on the build codes of my car and noting the oil cooler was not installed as required. However, I do not know if they will do this now. Good luck.

Thanks for responding. I will try a similar method and hope for the best... if they refuse to retrofit one, does anyone have any suggestions for an aftermarket method? It seems like most of the kits I've seen are supposed to attach to the cooler that I'm missing in the first place.

I have a 09/06 production car.
Look up how much of an oil temp difference will a oil cooler make.
Might want to put that into your calculation if you have to pay for it yourself.

Unless you track heavy, I decided not to.... And leave it.
Look how long the car has survived without it.

Same here. Don't have one, don't track, and the oil temps doesn't get passed the first tick after 200.

This is what worries me, it seems mine gets much hotter. This is from moderate freeway driving. It gets to this point on the regular but doesnt go past. Should this be a concern?

When I first figured out my car was missing the oil cooler back in '07, I high rev'd it to see how long before it went in to limp mode. I believe it was 2-3 minutes.

I do not believe mine has ever went into "limp mode". From what I'm reading, thats where your engine completely loses power? If thats true, that has not happened to me.

Does my engine temperature look higher than normal compared to everyone elses normal operating temperature?

Anyone have any experience using products like Purple Ice from Royal Purple? Not sure if this would be ok to run in the 335i. http://www.amazon.com/Royal-Purple-S...ct_top?ie=UTF8

My current oil is Mobile 1, 0-40.
Temp outside in was really hot yesterday like 33 celcius.
In city my car was at 2nd line past mid point. 210 mid point.
Was on the hwy doing 75 to 90 for about 45 min drive.
My oil temp looked like yours. 245ish.

What oil are you using?

Since I recently relocated to SoCal I do not have my DYI tools and necessities yet so I've been taking it to the local BMW dealer and doing the synthetic oil change special for around $80. I believe they use OEM BMW motor oil?

I do plan on getting ramps and jack stands soon and when I do I will also be using the mobil 1 0w-40

Second that. I have the same oil.

My car never has been that bad. If it gets bad the car goes into limp mode any ways. If it does that is when I would look into it. BTW i get 98k miles on it.

Yeah, so far I have not got any symptom of limp mode. Today I threw some Purple Ice into the cooling system, we'll see if it makes any difference.

stock thermostat doesn't even open until 240 iirc, so no worries unless you're consistently hitting >300

and congrats on the new ride!

Yep you get an yellow engine light and a loss of power.
Your temps run about 40 degrees higher than mine.
BTW, I run redline oil. Cheers!

This is why I don't use Mobil 1. http://www.animegame.com/cars/Oil%20Tests.pdf

Car operates at around 240-250. You are fine. If you do an oil cooler, go aftermarket. You only need it if you track though.
