Hello all, I'm having a few issues with the 7g tronic gearbox on my w204 c63, its feeling pretty rough when shifting in comfort (a bit lumpy), the clutch isn't slipping and there's no loss of power when on a hill etc. I have tried the adaption reset and it seems to have made it worse, i have rang Mercedes and they are wanting £192 just to diagnose the issue, any advice? thankyou.
