Tiptronic kick down

Recommended Posts

Hi all., recently while overtaking I've put the pedal to the floor and asked for a change down, none was forthcoming even though I felt a down shift should have been possible bearing in mind the revs, I'm not sure if the kick down switch is working. Normal gear changing apart from this, push the throttle down and it will down shift. Is there anything I could check....fuse etc?

I've noticed something similar on my 2000 S Tiptronic but later I realized I needed to press even harder on the gas pedal. I think there is a switch that detects a request for full throttle. I just walked out to the garage and checked this. In my car I can definitely feel a click at the very bottom of pedal travel when I press it with my hand. It's surprisingly stiff. A person could think they had their foot all the way down when it's not.

I was having kickdown problems with my '99 Tip until I did the 90K trans service and now it works perfect. I couldn't get it to downshift to first in manual mode even when the rpms were low enough until the service now no problem in manual mode either.

Interesting, although mine has only done 70k.

Mine had 74K mi on it when I bought it and it was doing it then. I went ahead and did the service at 84K mi just to see if it would make a difference. Neither my mechanic or I have any explanation of why it worked it just did.
