I believe I have a similar oil leak. I have a 2025 FL5 with 5.2k miles on the odometer. I took it to a local dealership and had the car inspected. They couldn't identify the exact leak location, but suspect it is the oil pan as well. It seems very similar to @k20.dennis situation with oil on the upper bolts leaking down to the main drain plug.

Same issue for me at 1800 km, dealer resealed my oil pan so hopefully it holds. If it doesn’t they’ll move to ordering a new pan.

Update:

Dealer is saying that their field tech has never seen an issue like this before, and will not replace the pan until they just do a reseal. I do not want to open the bottom end of this motor twice if a reseal doesnt fix it. From what you guys are posting, its a casting issue, not a sealant issue.

Mine said the same citing not wanting to waste a good part, which seems fair. Only couple hundred kilometers since my reseal but its holding for now.

You could always agree to it and request the tech takes a look at the oil pan to see if the casting seems flat/smooth.

Gotcha, I authorized them to go ahead with the repair. I will keep you guys posted.

Just for reference if anyone else comes across this, I did my first oil change at 1000 kilometers and it was already seeping. Cleaned it up and then rechecked at 1800 and it was still seeping so they resealed and want to take a look in another 1000. So mine was an issue straight away.

I’ll also check back in when I have more kilometers on it.
