Hello,

I'm newbie at remap'ing :D My problem is that sometimes I like driving economically and turbo vnt mechanism tends to become sticking. I heared that newer PD models have some automatic movement to move vnt mechanism fully to prevent it sticking.

Is there a away I can make vnt mechanism to fully move at certain times on MSA15 ECU TDI AHF engine?

Thank you. :thumbup:

just open it once, clean it and the problem is hopefully solved for a long period :D

in vcds you have an option to do VNT gymnastic, but if its already too sticky, this may not help you.

i would suggest to clean the turbo and maybe change the actuator (a few euros compared to the price of a new turbo..), this are usually the common problems of the vnt15.

Turbo is fine, before I put it, the lever moved freely :D It's fine when I do some hard acceleration, it fixes itself, but there must be a way to make turbo lever move fully at sometimes automatically to prevent it stucking. Then I will not need to do hard acceleration and waste fuel. This is why I am asking for help to solve this problem. Before, I had vnt15 turbo, now I have gt1749va, but same thing happens...

I had cleaned vnt15 before and changed actuator, also.

like i said, try with vtg gymnastics in vcds, some people use it weekly to prevent turbo from getting sticky.
