With OBD-2 on diesels the intake manifold flaps have been a constant problem. Surging & other problems on 1996 & early 1997. Check engine code P1 475 is related to the induction resonance flap. Cleaning the manifold & replacement of any sticking, binding, OR broken flap is the answer.
The P0 200 is generic & can mean 4-5 different items, including the P1 475. Might do search on OM 606 engine.
Some of the 1996 cars were a repair nightmare, SURGE!!!
