Need some help please guys! Boosted up a hill earlier, got to the top nice and fine.. Went to boost again when it flatened out and it boosted like the smallest bit then just dropped off, in all gears :l .. Stopped to see if any boost pipes had popped off but they all looked fine and wiggled a couple and both sides seemed secure, usually you will hear it if a boost pipe pops off tho soo! But yeah, really struggling to figure it out.. One minute it was boosting fine, all the way up the motorway, then up the hill, but then it went funny from there? :s. I don't have a wastegate of a BOV so it's not down to them not holding the boost. Could be be boost controller related? It just feels like there's no pressure anywhere.. Or maybe actuator? Any help is greatfully appreciated.
