big vacuum leak or leak between the AFM and the turbo. pressure check the intake system, cap off the turbo inlet and blow into a vacuum hose and check for leaks.

yeah sure, let me find where I put them! https://www.nopistons.com/forums/pub...#>/biggrin.png Theres a box of all the seals and such somewhere in the garage, hopefully they are all there. I had no intentions of reusing them so there may be some small stuff like corner seals missing... but you can have whatever is there.



also did you figure out if you can use the S4 power steering pump? mine works and is sitting in the garage waiting for someone to give me a few bucks for it... but I'm not sure if it's compatible with your S5.

S4 power steering is different.

bummer.

My power steering works now... I think. It moves freely now. I haven't put a belt on it yet. We'll see...



I'll take out the TID and double check that. Maybe there is more than just that little crack.

if you just unplugged the omp it won't let you push the car at all. Since the s5 cars have an electric omp, it can tell if you took it off.

pengaru 04-29-2003 02:49 AM

you can try connecting the OMP just to satisfy the ECU to see if it makes the car go, maybe some kind of limp mode. If it works you can probably

rig some resistor setup using the connector from the OMP (chop it off) and trick the ECU into thinking it's there that way.

yeah the ecu has a cow if you dont have the metering pump. yet another s5 shortfall. you cant hook it up with a resistor because the ecu looks for a resistance range, per load vs rpm. so if you put a resistor in you can get it to work in a 1500-2000rpm band. its best to tie the pump out of the way.

Oh great!!!!! I'l try that right away. Man I hope that's it.





Thanks!!!!

rmaiersg 04-29-2003 04:51 PM

Hey, it works! I just plugged in the metering oil pump tied it down with some wire and it worked. I was in a good mood so I filled her up with some 100 octane to get that nice smell. Kind of expensive but hell nothing smells better than racing fuel, ehh?



Thanks for all your input. It was much appreciated. rotary>piston, you're my hero!
