Oil Leak

I looked under my car today to find an oil leak under the front right part of the car. After everything I'm reading I think it might be the Vanos oil line, but now I'm wondering since my car is not under warranty anymore what will this cost me. I just bought this about 3 months ago from Fremont BMW. About a month ago my car was in for the check everything service and they didn't notice it. They also charged me for a new battery because I was getting the high battery drain warning and guess what? I have the same warning coming up again. Getting pretty frustrated with everything. Any help would be appreciated. Thanks everyone in advance.

I think it would be the Oil Cooler. This is a common problem with these cars.

If it is only the connector or the lines, you should not have to spend much.

If you need to replace the Oil Cooler, I would suggest the RPI Oil Cooler.

Good Luck!

Check for any aftermarket accessories that a previous owner may have installed.

I hope you are right on this one. I'll find out today when they call me back. Also, should I just have them install it since my car is already there? How much am I expecting to spend there?

As is noted, this is a common problem. If you look inside the lower grille at the top left of the oil cooler (facing the bumper of course), you will see this is where the two lines come into the oil cooler. If this is not where yours is leaking from, you may have a completely different problem.

Mine is leaking at this location, and there are several options. Replace the oil cooler, replace the lines, replace both the oil cooler and lines, or start small and work to big. Meaning, there are two o-rings which fit inside this connection. They are $4 each at a BMW dealership (part 8 on the link above). Crimp the lines and replace the o-ring. If the leak stops, problem solved. If not, continue to problem solve.

I purchased the two o-rings, and it should take me a few hours to replace and test. $8 and a few hours is worth it to me to try and address the issue prior to dropping it off at the stealership.

Stearlership has it

Unfortunately I didn't know what to do with it so I drove it into the stearlership this morning. They have it and are still looking for the problem. They just called me and said they need to have it over night and take a look at it again tomorrow. Pretty crazy considering I took it in this morning at 7:45 a.m. Is it really that hard to figure out where the leak is coming from?

+1 to oil cooler leak. Mine leaked all it needed was two new gasket rings and tightening. Goodluck. Problem is to do this you have to take the front bumper off which takes a little bit of effort.

+ 2 on the oil cooler leak. 2 o-rings and no more problems. Really easy to DIY.
