Hi Yoda S-Guys,

I have a 96//S6 with an Apexi boost controller, it came with the car that I=
 purchased only 3-4 months ago....anyway, a friend of mine had it for a week
while I had his truck,( I know, thou shalt not lend) when I got it back, th=
e coolant light was flashing, I topped it up and it stopped, but also notic=
ed that I was not producing boost.  My buddy, whom I believe, said he did n=
ot drive it hard, nor did he think it was running funny. It runs great, but=
 my Apexi, which use to show
boost of almost 1.25, now gets to only .5 on hard accelaration,  gone is th=
e noticeable whistle and neck snap.  I did notice
about a month ago that at about 140 k/hr and wide open throttle, it hesitat=
ed a bit, I put some injector cleaner in thinking maybe I had got
some bad gas.  It has been really hot here, + 28 -32 celcius.  The aux fan =
never seems to cut in, I swapped some same relays around and still
nothing, if it is out, does it shut down the turbo?  I looked to see if  a =
hose was off somewhere, but that would be too easy and couldn't see anythin=
g and
air filter seemed to look okay.  I have not taken it in yet to check the fa=
n or the relays.  The apexi boost settings look okay and everything seems t=
o be working fine on the controller, but I may be missing something. I have=
 the list of things that cause low boost from the Auto-technik site, but mo=
st of them look
beyond my means.  It is going into the dealer to have the dreaded fuel line=
 repaired, as I have a seping leak,  maybe this is causing my problem?  Any=
 thoughts?? ...I have limited my driving until I get the fuel line fixed. A=
t least if I could narrow it down I might save some tech time at the dealer.

Any advice would be appreciated....thanks


Boostless in Saskatchewan,...(and no, I don't think it's plugged with grass=
hoppers!)
