Mjet Low boost + smoke
I know there are many threads containing fixes for this, however ive tried everything i can think of but to still not found the problem.
car is 156 Mjet 140BHP 16v with an alfatune map to 175BHp (done a year ago)
Its always been smokey, before the map and after the map , gus blamed the injectors not closing if i remember correctly.
anyway, the low down whoosh boost has gone, boost is coming in at 2500rpm, but the low down turbo spooling isnt there.
done this list so far: -
clean egr, checked it moves with FES
changed AFM for a new cheap ebay item, no difference but did get repeated error code 1238 sometimes, so removed for orginal boash one
removed lower turbo to intercooler hose, no splits, cracks, looks fine but oily as hell, turbo compressor wheel looks dry
checked intercooler to manifold hose, again looks fine
checked booster controller with FES, can hear it clicking, checked hoses for boost controller down to turbo
can move turbo vane do dar that the boost controller should move with fingers
removed ERG valve again and inserted blanking plate, makes no difference and no MCSF coming up
ECU reset done twice now
In FES the desired air quality and the actual pretty much agree with each other when the engine is reved, but the desired boost pressure and the actual boost pressure dont, actual boost is always 100 - 200 mm lower and seams to top out around 1100 mm
I have a new lower turbo hose from autolusso to fit tonight, but thats not it.
only other think i can think of is the intercooler is leaking
any ideas ?
