hello! new here. 
There's so little knowledge of these engines where i live, and europe in general it seems, that most of forums suggested asking here. even tho the engine sits in a bimmer. this engine goes into the p38 iirc?
this engine sits in a 1996 325 tds touring, manual.
it's a lovely and robust engine when chipped and in a smaller car, but it just keeps loosing power after a short while of driving.
I've owned i for little over a year, and i've narrowed down the symptoms:
-happes only in speeds between 50-115kph.
-happes only when throttle pedal is either smoothly operated or kept in one angle (no constant adjustment)
-does not happen gradualy, or after a certain distance. happens all of a sudden but usually after 300-700m of driving. but does eventually always happen.
-sometimes theres more/less power overall.
-the fuel consumption gauge won't go over 9.5l/100, the car does accelerate with but very slowly.
-power comes back when you drop the revs below 1000rpm, even for less than a second. .
parts changed (because needed to, or from trying to fix the problem):
fuel pump (tank and injection pumps, both) brand new.
rebuilt turbo, with a new core and wastegate.
oil cooler and pipes
all filters
MAF sensor
wiring loom (well not new but mint used)
intake pressure sensor
fuel pressure regulator solenoid (loses power sooner now!!!)
throttle pedal sensor/potentiometre
i've also tried with another ecu and immo parts, but that made no difference.
fuel lines are ok and hold pressure (tested). fuel tank is fine with clean diesel inside.
no fuel leaks, no warning lights, no smoke.
one fault code: "20, vehicle speed control, control panel"
help me landyzone kenobi, you're my only hope!
