Car is Audi S4 2.7BiT and I?ve just installed HFS-3 system and I?m having problems with HFS-3, its not spraying. After install the system was tested by linking up ? INJ? and ?SYS?
on the controller and it was spraying. When I start the car the red "s" and w-injection lights are on in the gauge so it should be ready to spray but under acceleration I don?t see any bars lighting up to show water been sprayed.
