So, two months later, I've replaced MAF sensor, no change, than MAP sensor, still the same and small diameter turbo hoses, still the same. 17964 appears every time it goes into limp mode.
@justjust73, you mentioned turbo actuator being seized, do you mean wastegate actuator? if wastegate was stuck closed it rev itself to destruction.
I'm getting a bit desperate now. I have HEX-NET but can someone point me in the right direction as what measuring blocks to select or any procedure to follow?
please, any help would be appreciated!
