DCT Leak Recurring Problem?

[e924u]

Any way to check for this leak without using a lift to look under my car?

[BzsBimmer]

Just jack it up high enough to take the felt cover off

You need to get her up but you can sneak peak with some light without removing the cover.

Hi, just crawled under to inspect my 64k miles 2011 M3 DCT and looked ok to me. Wanted to post them to see if anyone thinks otherwise.

Thanks

It looks pretty good. Not 100%, but excellent I;d say. Mine is terrible compared to your. Car is a '12 with 27k miles. You are lucky!

Looks perfect to me! Reminds me its getting time to check mine since I got a new box 2 years ago. Although it should bloody well keep tight!

Please do some reading on the RS5 engine and the insane carbon buildup it has

Every single performance car has multiple issues. Every single one.

Just an update...

The DCT pan and mechatronics gaskets are again leaking with just 45k miles (and 13K miles after the repair). I am looking into a more permanent aftermarket fix (aluminum pan and Viton gaskets) to resolve this silly problem once and for all. If anyone has experience with the Viton seals and aftermarket pans being offered, your input would be appreciated.

Does anyone offer a Viton seal?

[KawBoy]

Never tried them.

Mine has a very slow leak on the mechatronics, minor; going to replace the gasket and cover (there are two revisions on the cover). Will also replace both filters.

Mine are leaking as well and I haven't replaced them yet.

if you had it repaired at the dealer i'd take it back. is it the pan that is distorting as well?

Mine weeps a very small amount and I haven't replaced the gasket out of fear of having your same experience... very frustrating I imagine.

I've had the car about two years and learned of this issue when putting the x-pipe in. I opted to simply top it off after reading of others recurring issues like yours. At the current weep rate, it would take a really long time to drain a considerable amount.

Not the ideal solution but I'd hate paying hundreds of dollars to have it "fixed" only to be at square one.

Hopefully the Viton seals work out!

I think many of you will be happy to read this qoute from another forum.

"Bmw stated on one of their internal technician videos that it "normal" for some fluid to come out of the vent at the top of the transmission during aggressive driving or in high temperatures. It usually runs down the passenger side of the transmission and looks like a leak at the side or bottom pan of the transmission."

Wow what a load of bs. Saw no vents on top when my box was down and even if so half of them are still leaking from the right hand mech side or bottom pan. And why would it be designed that way, its not like the fluid will expand crazy to need a vent...!

the fluid is under extreme pressure, don't think there is a vent anywhere.

The alu pans hang really low. I was considering then decided against it when I saw it on a friend's car. He also complained about scraping it a few times on stuff.

Yes, it was done by the dealer but BMW initially did not want to approve the repair under warranty. I suspect they would again fight the repair. In any case, I would rather just have something more permanent done at this point even if I have to pay for the parts and do the work myself.

If I go with the Viton seals and an aftermarket pan, I'll post up my experience.

I found one pan that claims to allow the OEM under-tray to stay in place, meaning the pan does not hang below the felt tray. It looks nicely made and actually does away with the OEM style gasket - instead requiring the use of a sealant (such as DreiBond).

[Ink09]

The only aftermarket aluminum pan I remember seeing / hearing about was the Gintani one and that one does hang lower and does away with the OEM undertray.

Is there another pan out there that is more durable than the plastic one that retains the OEM set up?
