Engine management issue/turbo boost
I have a 159 2.4 Jtdm. Recently the engine management light came on when accelerating past 4000rpm. Had it plugged in and the fault code led my garage to a turbo boost pressure fault. Checked for air leaks and cleaned boost pressure sensor. The turbo operation is all ok. Tried replacement MAF sensor but fault still occurred . Fitted variable geometry sensor which seemed to work initially had a good run, took it over 4500 rpm in every gear and a good 20 mile run out but unfrortunately EML back on again after accelerating past 4000 rpm a few days later. Completely inconsistent . Any ideas or suggestions would be welcome.
