      They are purely vacuum/mechanically controlled. Upper deck pressure (manifold pressure) pushes on the wastegate diaphragm, opening the wastegate valve at a set pressure. It's about as simple as it...

      Well, I'll wrap up this thread. You get all the fake money :P

      My car is a daily, so I hadn't had much time to take apart the front end and examine the intercooler connections until recently.

      Well I'm coming back to this after some time with a few updates.

      I mis-typed, but I'm still curious on the mechanics. I'm aware of how the engine speed on a diesel is controlled. What I should have stated from the start was "pressure relief valve".

      I suppose...

      I'm genuinely curious as to how a BOV prevents the throttle plates from closing (not diesel related, I know), especially on a car with a mechanical throttle linkage.

      My thoughts on the rings were...

      A blow-off valve's purpose is to vent intake air pressure (post compressor) in the event of an overpressure condition. On a gas motor (with throttle blades) this occurs when the throttle blades snap...

      Apologies. "Pressure Relief Valve", colloquially known as the blow-off valve.

      This wasn't the problem though, as the symptoms didn't change when it was blocked. Apparently, the wastegates on these...

      Thanks for the reply.
      All TD VWs have blow-off valves as a safety feature in case of manifold overpressurization. I believe it's set to open at around 13psi, so to boost higher than that it needs to...

      Sudden Low Boost

      Hi all,

      I'm having what seems like a low boost issue and am looking for some insight. Until recently, my 1.6TD would easily boost to about 12psi at very low RPMs and stay there until I let off. ...

      A small update to add to the confusion: vibration hasn't occurred again, but I now seem to be getting a maximum of 5psi boost, where I was getting ~12psi before all this started.

      It might be time...

      That's my suspicion, but the nature of the problem is puzzling me. My experience with bad motor mounts has always been the motor rocking under decel. and accel.

      I'll check the mounts tomorrow.

      Strong Intermittent Engine Vibration

      Hi all, looking for some opinions and advice. Had a bit of a head scratcher with my 1.6TD Jetta coupe today.

      I was thinking the same thing, is there any way to know if it was a special edition (e.g., flair)?

      dunc12's Turbo Diesel Coupe Thread

      So! I recently purchased a '91 jetta coupe with a full 1.6TD swap in it to use as a daily. I guess this will be where I document my progress through fixing all the broken stuff it has. :rolleyes:
