I don't think I had any issues with the DCT, there were a few times that it didn't down shift when I wanted, but I attributed that to the RPMs were to high. I don't believe it was due to heat. My issues were that the car would not turn! but its stock, on run flats.
It all depends how this car is driven. There is no way you can drive 135i at the limit with stock suspension and tires.
My car was heavily modded on slicks and i drive 10/10 most of the time on the track. As i said before, my DCT malfunctioned twice, and i am pretty sure it was tempr. related.
The point is, you likely will not have any issues with DCT, if this car is not driven at the limit.
