DCT is angry
Well, I may be effed!
I have a 2011 E90 DCT and honestly drive it like a grandma. I'm simply growing older and have kids, so I no longer cruise to work doing 110 in the emergency lane. The other day, I got a wild hair to burn some rubber. I pulled over in a vacant industrial area, stopped, put it in manual mode and 1st gear and hammered on the gas....no tire spin, but it did accelerate fast until I got to 5k rpm. I then experienced what felt like it popping out of gear and stopped. Trans light came up on the dash so I shifted to neutral, then back to first and gently drove off. dash light went off and all seemed normal. about a mile down the road while doing about 30mph I floored it and it seems normal for a few seconds, but then it cut power and the trans temp light came on. I have driven it once since and all seems fine. Any idea wtf is going on? clutch pack slipping? trans toast?

These trans are almost indestructible. I would not be worried about it being dead.
What code does the car throw? Maybe you have the typical DCT leak that has leaked enough to where there isn't enough fluid in there anymore |

I was honestly hoping that wouldn't be the case. This tranny had a previous leak while it was under warranty. BMW preformed a trans pan, gasket replacement and I've had a gut feeling since then that they didn't put the correct amount of fluid back in. Ever since then trans service, it seemed slightly noisier during gear changes, especially from N-1.
Because of the specific process required to change the fluid, what does a change cost? mine was under warranty so I don't know what it was.

i suggest you just refill it yourself. It isn't very hard. It'll make the car happy again and you don't have to worry. I'd use the GTS fill process and feed it an extra quart

I drained almost 6 quarts and was only able to add 5 back. I ended up following GTS filling process and added almost 7 quarts in the end. |
