Anyone has the same issue and being fixed before?

Thanks

Update:
Job finished by dealer today. They stated it was oil pan leak. They replaced the entire oil pan.not sure if it is necceary but they did it.

Will drive around and see how it holds up.

Have you pin-pointed where the leak is?
That's a mess...

That is the pits.... No leaks here after 58K. Not heard of anyone else having one actually in an F97/98. You've probably already done this, but I would clean and degrease all of that. Then put a good day of driving in, let it sit overnight and then look again in the morning.

On a side note.....My old f06 N63TU was an oil leaking machine.... After 40k the leaks started and then about every 10K (miles) I'd degrease and search out the new leaks that would sprout up. I had gaskets, vacuum lines etc. The only worse leaker I've ever owned was my daughter's 2009 R56 mini.... That little beauty sprung a new leak almost as often and I had to replace coils......

An oil leak on a BMW? SHocked...lol

Alright sorry, but I had to. As poster above mentioned, clean the area and then re-inspect or fill with liquimoly molygen oil and check with a blacklight. Unfortunately leaks are not uncommon, they just go unnoticed as its seeping onto the undercovers.

Common s58 leak areas include oil filter housing, valve covers, and timing covers.

I'd say those are common areas for BMW oil leaks in the past. But, there is really no mention of any common oil leaks for the S58 in these forums. I'm sure as these cars age we will start to see gaskets become brittle.

There have been a few and most of these motors are still sub 100K miles, While beautiful motors, there is nothing better about it that will stop any of the above mentioned items. We've had a few come through the shop for OFHG, 1 valve cover and even a rear main seal. Don't forget the oil cooler is mounted really low and while rare, a big rock to the cooler will drain the oil and seize the motor.

The B58 is starting to behave the way older models leaked and I wouldn't expect the s58 to be any different as the use of plastic parts persists and the platform ages.

The three areas you mentioned are likely probable causes for the OP's leak. There are however at this point hardly any common oil leaking areas reported in the S58. In time, I'm sure they will crop up.

I've read this as well: https://lifeonfour.co/engine-problem...e-reliability/

Hopefully this is not a sign of things to come, i have bad memories with my N54. My N55 and B58 were both "leak" free so i'm hoping for the same on this thing, cross our fingers this is not an "itis".

Looks like the rear main seal. But I could be wrong.

Uggggghhhhhhh I hope not. I'm having PTSD from past leaking RMS in other cars.

Can you see where the oil is leaking from or can it be residual from possibly the oil filter housing?

When I go in for an oil change I have to come home and clean under my X3m. The dealers no longer take pride in wiping down any residual oil from runoff or spillage.

Took to the dealer few days ago, they do not know…. They said something
Leak came out from transfer case and may need to replace transfer case and transmission…..

Car will go back in to dealer again for 1 week for repair.

Car is still under warranty. But I’m very worried after they remove many parts they can break some thing else.

Not happy………..

That just seems a bit odd.... Are you saying that the car was at the dealer before you started this thread?

They found all this oil leaking, which appears to be a significant leak, but then could not find the leak.

Then the dealer mentioned the leak is coming from the transfer case ??? They then said they may need to replace the Transfer case and the Transmission and then they sent you home with it?

I'm sorry, something about this just seems off. You may have the world's worst dealer service department.

Dealer took a look. But they do not have other car for me to drive around during the repair.

I have to go back to dealer again, then they will keep the car for the repair for 1 to 2 weeks.
Dealer said BMW usually ask to replace the entire unit if they can not find where the leak is.

Unless an oil dye test has been done or there is some other information to this, if it were me I'd go to another dealer.

Any oil leak can be tracked down using dye and UV light.

Is that the oil drain plug I see there?? Did someone leave it a bit loose??

Man, my garage looked like an oil pool from my E30. It is all mixed between steering fluid and engine oil. Wooo good time.

No fun whatsoever. But the silver lining is the warranty. Hope the repairs will be performed to your satisfaction, Looking forward to an update.
