Hi guys and girls, Not sure if this is meant to be posted in this section.... I've got a little problem with the boosting on the glanza, when i put my foot down the car would make an up and down kinda noise like it's struggling to boost. Can't really explain it so I've uploaded short clips of the car, mainly in 3rd gear it goes like this.. what is the problem and what is causing it?? It only started doing this after I've had my thermometer changed several weeks back, but then it went away for a bit, now it's back... sigh Clip one Clip 2
