I recently noticed that when I put my foot into it, the turbo makes a funny noise. The turbo usually makes a nice whir that gradually gets louder then fades as the boost releases. Now, however, it makes the same whir but with a vibrating/howling sound. It would be equivalent to the noise you make when whistling and humming at the same time. It's also sort of like a noisy antennae motor.

Any thoughts?

No. I don't have a boost guage. As soon as funds are available, that's what I want to get with the A-pillar pod. I haven't found a pod that is reasonably priced that looks good and fits well. I just checked the oil yesterday and I don't burn a drop since I changed it. I'm only 2500 miles into this oil change. What would be potential problems that could be starving it of oil?

I don't know what is the cause of your problem, but the easiest way to starve a turbo of oil is to cook the oil and have it clog the return line.

About your guage, you can get away with much less cost if you get one of the steering column pods. This is the route I am going.

Get them many places, http://www.newsouthperformance.com/pod.htm for sure. Even get it with the guage for about 80 bucks. Pretty good deal and seems necessary insurance for turbo monitoring. I wish I had one right now.. instead of the turbo gauge price.. now I pay the turbo pod price along with replacement turbo price as mine is to be repalced this coming week. So good idea to not put it off for long. :thumbup:

Good luck.

While I have gotten on it and even taken the opportunity to race a few ricers and hillbillies, I don't drive it hard and always have a lower speed (35-25 mph) final portion of my trips to and from work to let it cool down. I only have 17500 miles on it. Is it possible that the oil cooked with that sort of driving?

We took a look at it this afternoon and it does sound like the turbo is making an unnatural sound. He had a code stored for random multiple misfires and another that I didn't recognize. He wrote down the codes and will post them here soon.

The car is making good power and is making some boost. We tried watching the boost pressure with a vag-com but the measuring block that I thought would display boost didn't change with throttle inputs and stayed between 100 and 170 millibars. I'm going to play with it some more in a bit and see if I can discover how to log boost levels with this software.

Is your car under the warranty ?
Let a dealer take care of this problem.[/quote]

What fun is that? How can I justify all my expensive toys if I let the dealer do the work all the time?
