Hi, just got myself a Audi a6 2008 2.0 diesel semi-auto s-line after driving for a week it suddenly stopped and when in drive mode or reverse its not pulling at all, its making grinding noise when pressing down on accelerator when in gear , had bit of smoke coming from the front left side when tried revving it to see if it moves but no luck, hd computer connected and lots of issues/codes to do with gear box sensors etc came up. Was told it might be that it need gearbox fluid topping up or servicing the gearbox, anyone had similar issue?
