Code 234

[mberenz]

I own a 2001 Beetle TDI and I found that my VNT actuator was bad on the turbo. It was frozen solid and rusted out completely. I got a new one from www.idparts.com . The vanes on the turbo moved freely when I disconnected the old VNT. I'm not sure its adjusted right though, I think I need to apply 3-5"hg and it should start to open at that point.

The car was running fine after the install but shortly there after it would code 234 when you get on the accelerator.
The car makes a bugling (like an elk in heat)sound when getting on the accelerator between 2nd and third gear and even into fourth. I've swapped the n74 valve with the one next to it and I still get a code 234. My next thing is to replace all the vacuum lines.

Any other suggestions?

Check in the faq for info on adjusting the actuator but this noise, does it sound like the noise in the video at the bottom of this link?

Welcome to the forum.

There isn't a Code 234 all codes are 4 character so there is a number\letter missing.
