Does the automatic 335 have one oil cooler? - BMW 3-Series (E90 E92) Forum

Does the 6-speed manual 335i have two oil coolers?
Does the automatic 335 have one oil cooler?

Just a rumor i heard and was wondering if thats true.

roller84 · 01-07-2007, 06:59 PM

I believe there is a difference between the oil coolers, whether it be quantity or size. My dealer received a memo stating that the M-Tech Bodykit could be installed at the VPC. When I placed the order, they came back saying that they could not do it for my vehicle at the moment because mine was a stick and had sports package. When my SA inquired more about the reason, they said that it had something to do with the oil cooler.

Reason i ask is that the "overheating issues" that the audi guys noticed at the local track were driving automatic 335i.

Later we found out they had a bmw tech at the track few weeks ago and mentioned about the oil cooler thing. I was just curious if that is true. If it is then that whole overheating thing was really nothing major.

The "overheating thing" was bogus FWIW.

Jesal@Project 808 · 01-08-2007, 04:18 PM

If it was bogus then how did i hear about automatics having only one oil cooler?

I hope this is true because I ordered a manual....

By looking at BMW ETK, it seems in US, only those 335i with High Speed Synchronisation AND Manual Gearbox have Engine Oil Cooler.

wistarf · 01-09-2007, 03:16 AM

What the hell is High Speed Synchronization? I never remember seeing that on the options list...

I have no idea, but that is what it asks in ETK when you try to access the Engine Oil Cooler, both High Speed Synchronisation AND Manual Gearbox must be Yes or it will not show the part number for Engine Oil Cooler.

So, maybe the High Speed Synchronisation in the ETK refer to the sports package, so it is possible that in US only those manual 335i with sports package have oil cooler. Just my guess according to the BMW ETK.

this is exactly the information I got from a german tuner (Evotech). In Germany both (MT and AT) have oil coolers. Dont ask me why

Thats the reason why in US only 335i with MT could be tuned up to 375HP and AT "only" to 360HP.

picus · 01-09-2007, 10:28 AM

I'd like to find out the answer to this as well. I'm going to be pretty pissed if the MT has two coolers and mine has one.

sdiver68 · 01-09-2007, 10:38 AM

I just looked around inside my 335i Step Sedan. I'm used to oil coolers being in front, to take advantage of fresh cool air. I found the radiator and the a-t-a intercooler, but not the oil cooler. Of course I was very limited in what I could see by the various plastic covers which I have not removed and not having a lift. However, I did crawl around and used a mirror to see up into the wheel wells, which according to 1 BMW report is where the air-to-oil intercooler is located.

Does anyone have a schematic of where these oil coolers are supposed to be? Can anyone find one or two on their MT version, then I'll look in the same places!

jmonier · 01-09-2007, 11:11 AM

Oil cooler is supposed to be in the right front wheel well.

Not on my Step...and when you say right do you mean drivers or passenger side? Also, I've found a few posts where it was reported that BMW reps state that manuals only get the (2nd) external oil cooler, the first oil cooler being a coolant-to-oil.

If someone with a MT can see theirs, I'll double check but I spent some time seeing both entire wheel wells with a light and mirror...

My car is manual with sports package. the oil cooler is at passenger side. Here is the picture.

sdiver68 · 01-09-2007, 11:30 AM

Well I would not have missed that, it's obvious as day, I think it's confirmed that US Steps (at least my sport pkg sedan) have no air-to-oil cooler!

OK, now for some thoughts. BMW Reps stated that the A/T did not "need" a 2nd oil cooler, now is this because the M/T dumps more heat into the engine where the auto does not, or simply because BMW believes that Step drivers don't push their cars as hard?

I have an appt tomorrow for 2 TSB's...I'll ask my SA where my oil cooler is and make an issue of it, see what they come back with!

ac2 · 01-09-2007, 11:55 AM

According to ETK, only auto has Oil-Cooler Heat Exchanger.

sdiver68 · 01-09-2007, 12:14 PM

OK, so MT oil is cooled by air and Step by coolant, is that where we are now?

Refer to page 46 in the Engine Management document from the above link. That's all I know.

ac2 · 01-09-2007, 12:20 PM

I think only for US, because in ETK, auto in Europe has oil-cooler too....
