i have a 96 tdi A4 which has done 155000 miles, over the last few weeks i
have noticed a drop in power. this is more noticable when the engine is under
torque. The engine also kicks out black smoke when under strain, the car is
serviced frequently so i don't think its a fuel problem.. can anyone please
help me solve this..
i am thinking maybe turbo is on its way out..

Thanks Guys
