Default NE 2.5L Diesel Wastegate Actuator

Hi Guys,

For some time now my NE 2.5 Turbo diesel has been blowing lots of black smoke when accelator is pushed hard, no smoke at idle. At first I thought it may have been stale fuel, faulty injectors but today whilst looking at the wastegate actuator, engine not running I noticed that I could not move the rod going to the wastegate either up or down and appeared to be jammed in the static position. A few questions:
1. should I be able to move the actuator rod up and down with the engine not running,
2. should I be able to see the rod move up or down when I push the accelerator to the floor with the engine running,
3. what would I expect to e max revs, mine is 3200rpm,
4. would the lack of operation of the wastegate actuator cause the engine to blow black smoke,
5. any suggestion how I can fix the problem?

Thanks in advance.
