[Vwdiesel] 04 TDI Golf intake issues on trip

[Dave Cook]

A small boost leak that is only pushing through at higher boost?  Might sound like a whistle or squeal.  Unfortunately if it is that, it'll probably be hard to find as I don't think the computer lets the engine fully boost up when sitting in neutral, or maybe only for a second or two.  I'd look for cracks on the boost tubes.  If it is this, I would imagine a small little crack that seals up when there isn't much pressure (or when there isn't much pressure, it isn't pushing enough out to make a noise).  Because of this, I would suspect the rubber parts first.

Traveled around 1500 miles now from WI to WY. Did 500 today from Sheridan WY to Billings MT to visit someone and then do the Beartooth Mts and Big Horn Mts on the way back. When I got to the top of the Big Horns I started to hear some squealing like are trying to escape a bottle. After doing that to all the bottles I still hear something. Didn't take long to see/hear it was the car. Couldn't find the source in the dark. Didn't seem to affect things enough to strand me so I drove-slowly the around 50 more miles keeping the boost at/under 5 PSI as that is where the sound started to get really bad. Seems to have full boost. Doesn't make any noise at 2-3 psi. 

I can't believe the turbo is really failed if it still boosts and didn't suck the oil in. That is about all that can go wrong. I would think if it was making metal it would have done something by now with either the engine really going/sounding bad or something. Sounds fine other then boosting it. 

I am hoping for the shut off flapper in the intake manifold to be the issue. Maybe it is stuck part closed. I will have to start pulling things and see. I am a long ways from home but thankfully am staying with some friends who have tools and I have the week off. It just depends on how I will be spending it and how my family and the car get home. Hoping I don't have to rent a U-haul or something but we shall see. Any tips let me know.
