Alfa 147jtd 16v boost problem
I have a problem that seems to be quite a common one on the diesel, at first i had no power below 2.5k revs and now its no power below 3.5k revs. I have a new EGR valve fitted last year after a similar problem so this should be ok. I have noticed when the turbo finally kicks in there is more smoke than normal. i cleaned the MAP sensor but has made no difference. Could it be the MAF? Also i got error code 236 boost sensor A when the turbo kicked in but that seems ok after i cleared the MAP sensor. I checked the actuator rod movement while ticking over by removing the hose and the rod only moves 5mm, which i thought it would move more so possible sticking turbo? any ideas would be apreciated, thank you.
