XC90 2014 D5 R Design
 

G'Day everyone,
i have 2014 XC90 turbo diesel AWDIssue with hill start. If the car is on hill and want to go forward, car has no throttle response. I kickdown the throttle pedal but does nothing. If the hill is not so steep then car goes very very slow. in normal road has no issue. Slow response on throttle after stops. it does on both gear reverse and drive.
Mechanic has no sense of this issue.
