I have a 2001 Audi TT 225 and recently the check engine light came on with no noticable diffence in drivability except for constant fluttering after every shift. I suspect it would be the diverter valve but Its only 2 years old. Its an FK diverter valve. I went to my local autozone and had it scanned. Two codes came up.

P0411 and P1432
Both describing something up with the secondary air injection valve either being open or incorrect flow.

Would this be the diverter valve or the N75 valve?

Any information would be appreciated. Thanks

Secondary air injection Check valve. I'll try to take a look on my '01 tt 225bhp car today and see if I see where it is located. Your best bet is to go to the Audiworld tt forum and ask there, somebody will probably pipe in quickly.
