PD130 - Smoke after boost....wtf!?

[Midnightclub]

Had a similar'ish issue when i had the HDi, basically when not booting it for a while exhaust gets a buildup of soot and then when you boot it it blows it out giving you that smokey/black cloud type thing out the back, try driving it a bit harder for a little while and see if it clears up.. If i drove the HDi especially hard then the soot would ignite and you'd get small flames/embers coming from the exhaust
