Hi.. I have a 2004 2.0 tdi 140 bkd engine, I have problems when starting it from cold, takes a few cranks then it fires with a bit of white/grey smoke. Once warm it starts fine, been like it 6-8 months, In the last 5months it's had new dmf, 4 injectors with new seals & bolts, new injector wiring. Tandem pump, new fule metal fuel pipes that go along top of the engine, starter motor etc etc, been into a specialist, they seem to think it might be the fuel pipes in the head, does anyone know of these can be changed??or has anyone had the same problem?? Thanks Kyle
