PierburgOEM Turbocharger Bypass Valve / Cutoff Valve 7.01830.13.0 - 06H145710D

I was debating on getting the cheaper priced part that Amazon recommends you when seeing this product, but after seeing the reviews on them, I decided to just get this genuine one since it is the part that I depended on a lot. My car was suffering from loss of speed, and I didn’t really pay much attention to it because from glancing at what could be the problem with P0299, I brushed it off and said “as long as it runs I’m okay,” but this started to annoy me after 2 years of going with this code as I wasn’t getting the speed I used to get anymore. I sat down and went through what it could’ve been, and saw the diverter valve could more than likely be the issue. I wasn’t 100% but I was hoping it was because it seemed to be the cheapest and easiest part to replace. $50 is a godsend when it comes to replacing an Audi part. So the part came, and went to my mechanic to go get it replaced. When he took it out, the diverter valve in my car came apart completely (see photos attached). I was in shock and thinking “I’ve been running my car like this for 2 years? Man.” Got the part switched out and was happy that it was easy. Immediately after I left the shop, I felt it; the boost I’ve been missing for so long. It was as if the car had been waiting for this replacement and was ready to show its full potential. I am disappointed in myself for not doing this sooner, but I got discouraged when I thought I might need to replace the turbo ($800+), and did not have the money so I rolled with how it was. My car is back, baby. Now I’m just hoping the check engine light is off for my smog test, as that will confirm that this WAS the P0299 my car was giving me (edit: check engine hasn’t come back on after a week and the car passed the smog test, safe to say the crummy part had been the culprit all along). Other than that, if you’re still debating on getting this one or a $20 diverter valve, fork an extra $30 and get this one. You won’t regret it and your car will thank you.

Was getting P0299 code (underboost/loss of pressure) on my 2006 Jetta GLI 2.0T FSI. I was getting significant performance decrease and a louder turbo air sound.I removed the old diverter valve (part # 06F 145 710 B) and saw the diaphragm had several tears, so the turbo was not able to hold pressure. Replaced with this newer piston style diverter valve (part # 06H 145 710 D) with doesn't have the rubber diaphragm and should never need replacing. This should also fit anything with a part # 06H 145 710 G as well. For some reason D is newer and superior to G.Replacing was fairly easy. On the VW 2.0T FSI, the turbo is located on the passenger side between the engine and the firewall, sort of by the axle. It's really only accessible from the bottom, so you'll need to put the car on jack stands or a ramp. I unhooked the electrical connector at the bottom, then removed 3 allen screws (metric size 5mm), 2 on the bottom corners and 1 on the top that was very difficult to get to. NOTE: there is a 4th allen screw next to the valve (slightly below) connected to something else, and it is actually the easiest one to get to, but it is not part of the diverter valve, so don't unscrew it. The allen screws you want are all connected to the black part of the diverter valve, and that 4th one is connected to a silver/metal part. My old valve totally fell apart when it came off, so be aware for that or you might have a spring or something fall in your eye. Just do the reverse with the new valve, and you're good to go.There are quite a few resources out there if you want a more detailed guide, such as:http://www.carworklog.com/2008/06/28/guide-how-to-replace-your-diverter-valve/https://www.youtube.com/watch?v=lQfUQuACkNMhttp://forums.vwvortex.com/showthread.php?6066678-Perfect-replacement-for-your-Genuine-VW-Turbo-Recirculating-Diverter-Valve-(DV)-valve-06H145710D-06H-145-710-D-62-99

This is the latest version of the Volkswagen 2.0T turbo bypass valve, made by the oem supplier. Been using it for probably a year now without any issues. It fit fine and didn't require any modifications.

Works as it should and is a great OEM part. Now if it came with free installation I would be so much happier!

Good diverter valve, with the upgraded design, from the original equipment manufacturer for this particular part ("OEM" gets misused all the time, but not in this case). If you have the original in your 2.0 TSI (tfsi) you can count on it failing and it's probably already started to. It can cause quite a few hard to pin down symptoms before it completely gives out. It's quite an easy 3-bolt job (at least it was easy on my A3 8p from under the car). So, change it proactively. Tuners go with an aftermarket forge with a very different design (and it's own compromises you might not want if you don't have other performance mods) but I'm happy to have this inexpensive upgraded design that is a lot better than the older version.

Fitted this to my German car, but it did not resolve the P0299 error I was getting. So far it has been reliable and working as expected.

This is a redesigned bypass valve that is a perfect replacement for the original one that often fails. I didn't have a code or engine light but knew the boost wasn't up to par so pulled the original bypass valve and quickly found the diaphragm was torn. The car has the pull I was missing and runs like a bear now, I love it. The price was better than anyone I found and its not a cheap brand, after looking at the original I found the same brand name matched this part. It bolts directly into the bottom of the turbo, 3 bolts and the power cord remove it. Pull the splash pan and look up on the passenger side of your 2.0t engine, you'll see the turbo. This valve looks like the original from the outside so look and you'll see it.
