Tiptronic
I just bought a 01 S4 tiptronic and it seems to be always shifting into overdrive so when I step on the throttle it takes over half throttle to get it to move and feels like there is not alot of boost when it does. Has anyone had a problem with there N75 valve? I also have a check engine light on for secondary air injection with low flow and leak codes. I dont know if that would effect anything else. I could really use some help. Thanks guys.

Turbo bypass valves
Check your turbo bypass valves to make sure they hold vacuum, if they aren't then they can lower the
amount of vacuum supplied to the secondary air system and also affect boost performance.

Re: Turbo bypass valves
there not stock they are both forge dv and it has a problem with the idle too it will slightly surge at idle. I was driving on the freeway in traffic and once i hit 40mph foot slightly on the gas the tranny went into 5th and ran at 1400 rpm is that normal it seems everytime you want to get it to move you have to get it to kick down. Ill test the dv and see if it works.
