A turbo charged diesel engine works very very differently from your normally aspirated gasoline m103.
It is a well documented fact that a K&N is bad for ANY and ALL turbo diesel engines. Period.
This is not an m103, and your m103 tuning does not apply. If you only walk away with ONE piece of knowledge from this entire thread, it should be to put that K&N into the trash and install a paper filter instead.

ok, dude. i'll walk away with that and hopefully more. i fullly realize this isn't a gasser and not all mods are transferrable. but i also think you should consider changing your approach.
for the record i did state above that this is my first diesel car, so i'm new to all this tuning, even though i'm not new to this engine or chassis, having dismantled many a w123 before (almost completely)
