Tried searching the web and the various TIS type CD's Ive got, but cant find any codes there--Plenty for the Motronic systems but nothing for the Digital Diesel Electronics......

A full list would be really appreciated...........

The stomp test (Which does work for the DDE) shows three recorded errors

15 (which I think may be the charge air sensor, as this code appeared after I messed around with it.............)
29--No Idea.
30--No Idea.

Irratic idling, mis-firing and poor starting with heavy diesel-knock for half a second after starting are the engine symptoms. Driving shows hesitancy at around 2K revs, not gear dependant. Boot it and it pulls fine, with no apparent mis-fire no smoke or nasty noises.......

Is it possible to erase the fault codes without a special gizmo--Tried the Motronic erase proceedure which does not work. Any help appreciated........
