Black smoke on acceleration
My 2002 V70 D5 SE Auto with 145k miles suffers from black exhaust smoke when accelerating after cruising. The problem has existed from new and the dealer fitted two complete sets of replacement injectors in the first 18 months, but the problem always swiftly returned. Once the black smoke is blasted away, the exhaust is clear until the next spell of cruising. It doesn't smoke when cold. Any ideas? With winter nights coming, I am embarrassed by the effect on following traffic.
