      Wanted to kick up a thread to see just how common OEM DV failures are for the TSI.

      Most TSI's should come with the Revision G or Revision D.

      Mine came with the Revision G; I had an issue where I was sporadically throwing EPC light. I had no idea what for but at some point I decided to replace DV out of preventative maintenance and it fixed my EPC issue. I replaced it with an OEM Rev. D and while the EPC was gone, car did feel a tad slower and less responsive. I ignored it until I recently had my clutch done and the guys over at APTuning said my DV isn't working properly. It hasn't failed, but they said it definitely wasn't working right.

      Here I was thinking these things were bullet proof; but even superman has his Kryptonite. I guess revision D's is Unitronic Stage II

      I wanted to hear from the crowd, what DV did you end up going with after yours failed/you decided to replace.

      I'm thinking AWE DV will be my next move simply because of the cost.

      My car had rev G.
      I had some intermittent boost issues when I went stage 2 so I snagged a rev D DV, when I pulled out the Rev G it fell out in 3 pieces lol. The rev D is holding up just fine now.

      I was origionally holding out for the BSH DV Relocation kit, but its been 2 years of waiting...

      Remember those days when we were all waiting for BSH to release one for us?


      I went Rev D myself about a year and a half ago, I don't even think about it anymore. Works great on big turbos too!

      I never had issues with G. I went Rev. D as a preventive measure.

      the awe is nice. I replaced my D with it. The D with my twintake had that weird spit noise but with the awe its more of a pssh sound(sounds smoother). I feel like awe's dv holds boost a little better than the D. I do feel that it isnt quick to get rid of boost as the rev d but at the same time it doesn't allow for any surging. its a great buy

      Ordered the AWE yesterday. We'll see if it changes the flutter issues I'm having.

      To recap, at time when I abruptly let off the throttle, the flutter changes to deep bassy 'boonnnnnn' vs the middle of the road pitch "schuuuuuu"

      Installed the AWE; power is back, car drives sooo much better; no more unnecessary intake noise but the damn thing brought the EPC problem back At least once a day I get the EPC light. Turn it off, reset the ecu and turn it back on and it generally goes out. It's driving me absolutely crazy !

      you throwing any soft codes when you scan it? maybe you have intake manifold issues or a leak somewhere?

      Replaced the manifold a few months back. I was epc free with rev d but the rev g and now awe are throwing the light. Only engine codes I throw are for my o2 sensor

      My issue I don't think is DV related, I'm still not sure while the EPC stopped with the Rev D and came back with the AWE but I'm throwing codes for Throttle body positioning sensor.

      It sounds like this may have been a preexisting condition. Your Rev D valve may have been leaking, and hiding the TB issue. Once the AWE Tuning DV was installed, like you mentioned, the power came back, and there was no more leak. With the initial DV leak fixed, the proper amount of pressure is now passing through the TB, and causing the codes, and EPC.

      Correct; just yesterday I noticed fluctuations in the boost gauge; when I make it to 15psi boost will waiver between 13psi and 15psi a few times before heading all the way out to 18/19. Before the AWE DV I was maxed at 16psi, never held anything higher.

      So in fixing the DV leak, I've brought to light a preexisting issue that just wasn't noticeable before since I wasn't reaching my potential boost levels. I'll have to run some logs and figure out what exactly has gone south. I'm thinking it's an issue with the Throttle Body or the TB wire harness; gonna cave and take it to VW

      Thanks Joe

      To those running the "d" version diverter valve...is there an audible difference between the "g" and "d" versions? Just curious as there IS a design change there.

      G sounds different than D, G is more of a longer whoosh in between gears, D is a bit "tighter" sounding and has a bit of a flutter to it, due to the piston vs. diaphragm design.

      at least thats how i describe it

      Well put; AWE DV sounds a lot like the G, a little more abrupt

      Figured I'd stop by and note that fluctuation and EPC have all been sorted. I was finishing around the engine bay and found that the Throttle body plug, while it was plugged in, wasn't clipped. I'm assuming this caused a poor connection triggering epc's on first start.

      hesitation at 15 psi has smoothed out as well but I think that happened after the introduction of a proper full exhaust. Even with a wayne angle block, I'd still throw CEL's from time to time (catless 3" and oem exhaust on a GLI) Since I've moved to 3" catback, car has really opened up.
      just a follow up

      Is there an easy way to tell which DV I have in my 09 besides pulling it out? I heard of some dealerships replacing it to the new "D" valve. I am going to the dealership on Saturday for my APR tune and figured if I had the old valve, I could just have them replace it while I'm there.

      You most likely have the G, and to be honest, the G's were designed pretty well. There is no real way of telling without getting under your car and taking a good look at it. Depending on what stage you go with you should be fine with the G. My car responded better with the G on my unitronic stage II. I moved to the D and had a slight loss in boost, then I got tired of playing the guessing games and switched to the AWE which has been great. It's like a peace of mind, I shouldn't have to worry about this DV failing during the time I own this car.

      That "great design" fell out in 3 pieces from my car.

      I have no boost gauge to tell, but she sure does fall flat on here head around 5k. Is there a good(cheap) boost tap kit anyone recommends? I'm going Stage II APR tune BTW...I just wanna make sure all my basis are covered before I go through the tune

      That "great design" fell out in 3 pieces from my car.
      Rev D FTW.

      They all disassemble easily , I pulled my d apart to see what made it so much different. Coming apart doesn't mean it failed, rips in the rubber means its failed.

I moved to the D and had a slight loss in boost, then I got tired of playing the guessing games and switched to the AWE which has been great. It's like a peace of mind, I shouldn't have to worry about this DV failing during the time I own this car.
      Can you elaborate on where you saw the boost flux after switching to the d valve.

      Any of you that had the G version fail did you notice any oil on the DV itself or around it....not leaking but oil film?

      So in fixing the DV leak, I've brought to light a preexisting issue that just wasn't noticeable before since I wasn't reaching my potential boost levels. I'll have to run some logs and figure out what exactly has gone south. I'm thinking it's an issue with the Throttle Body or the TB wire harness; gonna cave and take it to VW

      Thanks Joe
      This reminds me exactly of my current issue that I haven't been able to solve for either. APR stage 1 and same thing; I'll go WOT, get to about 15PSI and the gauge will bounce around between 12-15 before climbing to 16017 and dropping off. I have an audible whistle from the passenger side when in boost/at WOT which made me think the DV was failing.

      I occasionally get that whistle as well, but boost gauge reads pretty accurate in comparison to my friends so I've never been too concerned
