HELP!!!!!! My S4 is only running 5psi??????
Hello All,
My 00' S4 is now only running 5psi with a MTM ECU and a stock ECU, it is slow!!!!!
Does anyone now what would cause this????
Could this be attributed to bad Diverter Valves??? Can this be checked with the VAG-COM??
If anyone can give me some info on why this is happening, I would appreciate it very much.

Check if there is any boost leak...F-hose, TBB and etc...
check with VAG tool if you can. If you get 17965 or 17535, chances are your F-hose or TBB is ruptured. That was what happened to me...

It's behind and under the passenger side BPV...just run your hand under and around the hose...
you may be able to feel the split. If you see oil residue on the F-hose or around the area, your F-hose is ruptured. You need to remove the BPV to replace it though.

I checked the F-hose and it is in perfect shape, so I guess I will have to check it with the VAG.
