Check turbo tubes for oil. If wet turbo is leaking. otherwise you may have rings leaking, how is compression?
Also there is a crankcase pressure soleniod in left side of enigine block, it should NOT rattle.

Thinking of buying an a4 tdi 1.9 diesel - seller says it smokes (grey) under heavy acceleration. Should I avoid it? Or is it livable wth (200k mileage)


grey smoke on acceleration is NORMAL for this engine,white or black avoid like the plague.....you could use an injector cleaner,redexe/wynns or similar.i use it every 25k,and (touch wood) no funny noises/smoke YET.expect oil consumption to be better than 500k per litre or a rebuild is needed.

blue smoke would show a lean condition. most likely a fuel line leak between pump and tank not a pressure leak.or a check valve is allowing fuel to run back to the tank

well the question is where did the coolant go. if it didnt leak out it must have went out the pipe. As you stated, white smoke, white smoke is coolant. You definately need to get this to the shop. You cannot drive it this way or further damage will occur.

6.9 litre diesel losing power over last few days of driving, changed fuel filter no difference,cannot get enough speed up to allow trany to shift, bogging bad. and blowing blue when reved, not black....


Blue smoke is oil. With blue smoke and no power you should take the truck to a diesel reair shop to have it looked at. It could be that the valves need adjusting or it could be broken rings or a cracked piston, all of which are beyond the scope of online diagnosis. With a diagnosis in hand, you should pick up a copy of Haynes Diesel Engine Repair Manual, part #10330. It can help if you think you want to attempt the repairs yourself. Hope this helps.
