Hello community! I really don’t have a Volvo V70TDI D5252. (Audi 5Zyl.) which has already 510000km down. If the engine still brings massive power, and sounds mechanically very good. Oil consumption is not measurable. 1. The only peculiarities that the engine has is a bad start over +8°C (where definitely not glowing) or warm engine, which stands for half an hour. In winter at -20°C the old diesel always starts up on strike. (then it glows well ahead) 2. When accelerating the engine almost always makes a proper black cloud. Consumption is in cut at 6.8L diesel on 100km What I have tested and done so far: battery 75ah 760A EAN glow plugs renews starter breaks clean new smeared off. Top All 5 nozzle sticks with new inserts, and on the nozzle test bench again? however, the error of the diesel filter has been renewed with Wapu, and tension roller.
