How does the new engine differ from the old one - would the new engine have come with a VNT? is it the same CC etc
Im thinking the new engine is supplying more energy into the turbine?
is the electronic controller for the vaccum on the pumatic actuator connected/ working right
it may be possible to run the pnumatic actuator directly from the turbo (without the electronic part) the pnumatic actuator may be set to work at a set boost
Did you know with the fixed vane turbo you can fit a (seperate) adjustable electronic boost controller, so you could turn your boost up/ down as you drive?
Do you want more power or just want it running well/ reliable?
Its the same engine, 1.6 tdci 66kw version. Old one was -06 new one ~-09. All the numbers match... And ofc, the old one was 14 valve (valvetrain went haywire) and the new engine is 290 000km less driven.
I could assume it works right. During engine braking boost drops to 0, during normal cruising its ~0,3 and when accelerating / driving up a hill its ~1.
Im not looking any extra power atm, just curious whats causing it, and how to possibly fix it. It doesent bother me that much, since you dont notice it on everyday driving. but it still bothers a bit
