Same silver 110 problems

[E F]

Hi I have same silver 110 4 cylinder turbo that seems to be slipping in the powershift, the middle range (tourtise) anyone any ideas
Also seems to be down alot on power lately with more blackish smoke thanks

Hard to start?

Medium powershift is spring operated therefore you have an internal problem. Black smokes indicates un burnt fuel. New clean air filter? Turbo works as it should? Intercooler pipes all intact, no splits?

Air filter replaced, turbo seems ok as does hoses. Would solenoid be an issue with powershift?
