Hello I have the following problem with my Renault Koleos. If I speed up my vehicle no more than 130 km/h and as soon as a climb comes he loses his power. The kickdown doesn’t work either. I had the vehicle already three times with Renault, but they don’t find the fault and told me to pull up the winter tires because it might be because it’s because of it. Who can give me tips or help with the removal of the error? [Transferred from engine talk from the topic ‘problem with a Renault Koleos’.]
