Hi. I’m new to this club & need some help. Has anyone experienced oil leaks around the front differential or have any ideas where it may be coming from?
Today I noticed what looks like oil drops in this area. Ive attached a few photos.2014 Levorg with 87,000kms on the clock. Cheers in advance

haven't looked at mine - as long as it was under warranty, only the dealer was seeing her naked ;)

Is that diff plug the drain one, or the fill one ? It looks like it may be leaking from there - I'd recommend finding an appropriate torx bit and see if it's proper tight (do not over-tighten it though - stripping that thread is gonna be mighty expensive).

If it's tight, well, I can only recommend draining it, replacing the little copper gasket/ring that should be under that bolt head, and refill (by the fill plug, that should be somewhere up higher) - diff oil is thick though. you may want to warm it up (warm water bath - bain marie ?) before you try to get it in there with funnel/hose/etc).

[edit]note that if it leaks, it may be worth cracking the fill bot open and see if you still have plenty of oil in there. fill method is put oil until it leaks from the fill plug hole, unless there is a bespoke dipstick.

Cheers. Yea I think it’s the drain plug, my first thought was if it might be coming from there so good to have a similar opinion.
I had a mechanic have a very quick look at it & his advice was to clean the area, drive it for a week or two & see if it reappears in the same place. I think I’ll crack on to getting that plug & gasket replaced/tighten. Appreciate you help mate!

That mechanic idea is smart too - it will confirm that it's really leaking from that drain plug, and will also give an indication of how fast it leaks ;)

Could be that the dealer has done a drain/refill, but not replaced the washer...
