got a 200tdi 12L had the cambelt chaned and now I have a diesel knock and its black smoking excessively going to try and advance/retard the timing but wich way do I go?
 
retard if its knocking which is turning pump pulley nut anticlockwise after undoing the 3 bolts ,never undo the nut though, providing its diesel knock and not mechanical

When its ticking over sounds sweet just get the diesel knock when revving also seems to come around 2300 rpm and can be heard when letting off the throttle as the revs drop, the black smoke is driving me mad but I think the star wheel may need turning back a few teeth

well if youve altered the pump settings smoke and timing is a bit irrelevant
 
I've not touched the star wheel I'm just thinking that may be causing excessive smoke not sure if the previous owner had messed as the seals missing on the smoke screw
 
black smoke is more fuel than air not a timing issue , ie pumps altered ,your going uphill and revs are forced down ,restriction to air intake
 
That would be the logical place to start easy job as well, plenty of vids on youtube
I think what James is getting at is, theres no point adjusting anything until you know it runs fine on std settings
