Might have a leak

[DenisC8]

Found 6 drops of what looks like oil by the rear driver side wheel. Lifted the car, got underneath and everything looks clean and dry. Put cardboard down and will see it she leaks again.

Anyone have any leaks to report?

Other forums users report transmission leaks because of defect in the casting... something related to porous aluminum.

Keep us posted.

What colour is dct fluid?

 

[Jack Raccoon!]

Fluid way over on the drivers side? Not tranny fluid...

Forum research say it might be hydaualic oil from a leaky seal in a hydaulic transmission mount

Do you have the front lift system? I heard reports of hydraulic fluid leaks. Apparently an easy fix.

I’m sure your dealer will be able to diagnose and repair. Nothing to worry about.

After 5500+ km no leaks anywhere on my C8 with front-end lift and friends with C8's report the same with theirs. So it's unusual and as others said, talk to your dealer. But you're right to investigate to try and pinpoint and if it happens again, take photos and also keep a sample of the fluid to show the dealer.

Well apparently the cure for a leak in transmission case (too porous) is to replace the transmission. I would not like that to be done to my new C8.

It has been reported that some have the "porous" DCT leak and others have an axle seal leak. Both will leak DCT fluid that is clear(ish). If you can remove the lower pan under the DCT, you may see more evidence of the leak. Take it to your dealer to investigate.

I plan to take it to the dealer on Monday

The following day, no new oil spots before or after a spirited drive. Now my family say “are you sure those where not there before?” Well, I can’t remember as it could be oil or grease from when one of us sorted the trash.

 

[Murray20c8]

Or the Amazon delivery van! lol.
My driveway is covered with spots thanks to them.

 

[DenisC8]

its been 1 week and not a single new drop of oil so no need for a trip to the dealer (at list not for the reason of the mystery oil leak).

 

[DenisC8]

dealer found no leaks when the car was in for an unrelated issue

Great news (for you and all of us)
