      That is correct. They all are connected on one side to +V, and for each injector there is a switching transistor in the ECU that pulls the other side to ground to actuate the coil.

      My hypothesis...

      OK, I realize now that you're referring to all the coils--not the injectors--having grounds, which is not relevent to the problem you're having.

      I would suggest that you check the things mentioned...

      I would've done some checking on the suggestions noted in this thread before risking burning up a new injector.

      No. The injectors are supplied with +12V, and the ECU switches the other injector terminal to ground to fire it. These pulses have a relatively low duty cycle. If that switched side of the injector...

      I'd suspect mostly a short to ground on the line from the injector to the ECU, or possibly a short in the ECU itself. This would turn the injector on continuously instead of in short pulses.

      Any codes? Can you do a vag-com scan?

      Stumbles at idle are often caused by a vacuum leak, but there could be other issues.

      I'd replaced several of these switches over the last five or six years because of leaks.

      I installed a new PS pump about a month and a half ago and for good measure put on a new switch and crush...

      OK, if it's one of the regular wires connected to the fuse box, then it should be connected to one of the fuses. You should be able to tell easily which fuse it is, and pulling that fuse should...

      So is this some added-on wire from the battery into the firewall? If so, someone did a half-ass wiring job.

      Check the owner's manual for your car. If it designates hydraulic oil—such as Pentosin CHF 11S (synthetic) or CHF 202 (non-synth)—for your power steering, you definitely should eradicate as much of...

      I agree. Something pulling that much current should be fairly easy to pinpoint; that's 120 watts of power going somewhere and not accomplishing anything, so it must be turning into heat. To get an...

      The "brass hose" is actually the base of a pressure switch on the high-pressure outlet of the power steering pump.

      There are several things that can leak there:

      The presure switch itself....

      For one thing, it's a lot more durable. The stock DV is a diaphragm type, and is often prone to tearing, especially on chipped engines. You'll never rip a hole in the aluminum piston of your Forge.

      Is the tube free-standing on the 2.0? Maybe someone who's familiar with the 2.0 should know. My engine is the 1.8 T AWP and the bracket that supports the SAI hoses, N249 valve, etc., has a tab that...
