I've just picked up a part for my 300TDi 90 - a tappet adjuster screw.
I've basically had to go round all of the garages in the local area to see if anyone had one.
Now I find I've been given the part number for a 200TDi, rather than a 300TDi, and so have the wrong part.
How different is err559 (200TDi part) from ERR4883 (300TDi part)?

Does anyone have a spare ERR4883?

The locking nut is the same item for both engines!!!
