Hi everyone, sorry if this is a total newbie question. I bought a S5 Turbo II last year, and the turbo stopped working. I removed the turbo to inspect it and to do some much needed cleaning. I also replaced the cracked rubber inlet duct with a Corksport TID. The car was apart for most of the winter because I couldn't work on it when it rained. Other priorities also put the project on hold. I've got everything back together now except for the blow off valve. I forget how it was installed . I remember that the previous owner had the HKS blow off and the stock blow off both in the car together and it worked. If someone has a similar setup or just knows how I should install it, I'd appreciate it. Pics would be helpful too. Its a HKS sequential blow off.

 

I don't see why anyone would want to run an aftermarket BOV with the stock bypass valve/BOV. Assuming you're using a stock TMIC, you probably have some aftermarket replacement for the pipe that goes between the turbo compressor outlet and the intercooler. Either vent it to open air, or recirculate it back to the TID. Don't use both; there's no point.

My recirculated stock BOV with custom TID if it helps:
