Hi Guys hope you can help.
My 1.6 tdi 105bhp engine after 6 years of ownership decided to lose turbo pressure and go into limp mode.
i done a vacuum check to find out it was the actuator was not holding any pressure so ordered a new actuator off ebay (VNT Turbo type). and fitted it yesterday.
the actuator is the type with 2 nuts that go on top and underneath the vnt arm. i measured where to old upper nut was and put it in the same spot on new actuator.
After fitting i have took it for a test drive, car seem a bit delayed in coming on boost now but apparently it needs to learn again as its been driven around on 0psi for about 50miles.
I am hitting about 22psi on peak. its seems ok but when i come to idle at a junctions or on heavy deceleration it goes into limp mode and flags the boost fault.
I predict the actuator arm might be a bit out as its a different make actuator so could have slightly different pressures, is there anywhere which will show me the correct settings to have my actuator , i have a hand vacuum pump so can see what its pressure/vacuum is at when at vnt stop. i just don't know where to find this info? any suggestions?
thanks in advanced
