I'm trying to fix a S7 1996 at the mo, 2nd turbo doesnt come on line at all and primary turbo builds boost on first acceleration only then only builds 4lb or so until revs are dropped almost right back. No codes are showing and being a s7 there is no rats nest to sort through.
There is heaps of info on the net for s6 but I can't find anything specific for s7, can anyone direct me to a helpful site? Thanks.

Howdy,

I have problems with my primary turbo and like you i have no rats nest or diagrams to refer to. I managed to find these diagrams (better than nothing) I hope this helps you and if you by any chance come accross a complete vaccum diagram for post 96 FD's please share the info.

Thanks for that. Unfortunately there doesn't seem to be much info around for Series 7 models. I'll post up any info I come across.
