Ldv maxus 2.5 Diesel VM engine 95bhp 3.2ton
My 56 plate ldv Will start and idle on it's own power, but will not rev past 1500rpm, and then begins to knock a little, throwing out a lot of black smoke out the back. Will drive slowly only using the clutch and low rev but won't rev up. The edc light is always on. I have only so far taken off the egr valve, which was stinking and a bit seized, but cleaned up and moving and been put back on but same problem. Anybody have any help or idea? I'm going back to the yard tomorrow to tackle it a different way, like maybe swap the throttle body from my other maxus(same van) to see if it that etc, i can only guess at the moment until somebody gives some professional advice/help. Many thanks! Josh

sounds like lack of air , egr stuck open or cat/exhaust blocked ,turbo siezed, inlet hose colapsed /split etc! some have a throttle butterfly in the inlet manifold make sure thats fully open...

Throttle body? On a diesel?

Get it plugged in and have the fault codes read. At least then you will know where to look
