100% Oil, it was coating everything, even the fuel was black when they drained it and it stinks. Car feels under powered, can't see why the map would cause this after 18 months.
Yes, 140 Tdi, mapped by AMD to about 190ish and de-catted, 18 month old turbo, all serviced and had a good flush.
I think I will have to sell it once its fixed just to pay off the debt it's caused trying to fix it.
