Oil Cooler Oil Leak on New M4

slaughter.mode · 05-26-2018, 06:58 PM

Maybe this is from the ground but as I was re-torquing my front end suspension (trying to get rid of steering click post MPHAS install), I noticed this while sliding out from underneath the car. Hard to say if it splashed up or down but I went ahead and cleaned it off and going to drive a bit and park over a piece of cardboard to see if it accumulates. Oil level seems fine...dealer time?

When was the last time you changed your oil? Is it on the oil filter side of engine?

Oil was changed I want to say about 5 weeks ago? By the dealer. Yes on the oil filter side and the first assumption I made was the techs were just being lazy but I didn't see any oil around the filter housing...but they could've just wiped it up...

Update, also to add-I didn't see any oil on the top of the cooler...so I'm kind of scratching my head here. Perhaps I just need to get it back up on the raceramps and pull the belly pan off.

I'd take it to the dealer. Answer their questions as if you were questioned by the FBI. Yes/No. Mostly No.

Ha, understood.

Took into dealer today. My SA called the foreman in and he took a quick look and said, "yeah I don't know what that is but I'll just change the oil cooler, piping, etc. to be safe, that's definitely coming from one of the lines but it's not good." Case closed, kind of worrisome though on a BRAND new car to have this issue.

Update: My SA called me to give an update. They changed the oil cooler, it was leaking. Wow. Brand new car without any damage to the oil cooler but it was leaking anyway. Kinda scary but case closed.

Glad the dealer took good care of you.

Thanks for posting all that. Anybody else know of spontaneous oil cooler leaks like that?

I would recommend everyone just take a quick peek. They failed to mention anything about it when it was brought in for it's 1200 mile service not long ago. The rate of which it was leaking is so slow it had to have been an issue then as well. Also got a free oil change out of it (of course).

Here it is, picked up the car today...sure enough they swapped the oil cooler and o ring and some other thing I've never heard of (NON-CHLOR BRAKE PARTS C). They did not, however, fill up the oil so it's half way down the "OK level" now...they are so lazy:

They should top off the oil. Is it on page 2 by any chance ?

Nope. The oil level used to be max, now it's half way down the bar...I asked and my SA stated there was no need to, because it was still within "OK" levels. Horrible man...just horrible. The whole experience with this dealer was poor.

dim635csi · 06-01-2018, 10:51 PM

go to other dealer. There are multiple decent SA in the area.

Still, good catch with oil cooler small leak - it could be much more damage involved.

BzsBimmer · 06-02-2018, 09:25 AM

I wouldn’t worry about the oil. SA is right. Still within spec. Ask for an extra liter of oil and put in trunk.

These electric gages are finicky. If you add too much, you’ll have to drain.

I think the dealer added oil though. Hard for me to imagine that replacing an oil cooler is only half a liter.

True, been dealing with their strange meters for years. I did ask for a quart and they tried to sell it to me. Funny as my next scheduled maintenance interval is in ~9K miles. Surely these engines burn oil like every other BMW high performance engine-right? And I'm sure they know that, too. I'll ask the new dealer I'm going to next week to look at another issue they refused to fix to top it off.
