DCT Oil Change (X-post from M2 Forum)

DonPedron · 04-10-2022, 11:07 AM

When did you change the transmission fluid in your DCT m3/m4?

BMW states "lifetime". Keeping this car (M2) for a long time and a fluid change seems cheap in the long run compared to fitting a new gearbox in the future.

Currently 48000km on the clock. Dealer states around 1000€ for labor, fluid, filters and new tray. Seems reasonable.

Did mine at 60k kms myself.

As you mentioned parts required:

-DCT oil ~8L
-2 x filters
-Oil pan
-Oil pan bolts
-ISTA to run the bleed

I'm planning on doing a full service at 50k miles.

I’m at 60k miles and still at factory oil.
Not sure if I’ll replace as I haven’t seen data backed evidence it’s truly needed.
