Default P0238 - time for new turbo?

Hey folks,

My 09 pathy has been running well for the past few months since I fixed the vacuum to the BCS.

Recently I have noticed that when the engine is under load and I have constant pressure on the accelerator, it seems to sometimes lose power and the speed and revs drop. Suddenly without a change in input from me the power comes back on and off we go again. During periods of low power I get black smoke from the exhaust. As soon as the power is back, the smoke stops.

Roll forward to last week - on a little trip from Sydney to Melbourne and I get an engine light come up for the first time. I checked the code - P0238 which I believe is turbo overboost. I cleared the code and drove on. During the trip this happened 4 times.
I have cleaned the intercooler about 4000km ago using a can of magic spray that my mechanic uses.

My theory is that the only thing that could cause a lack of boost and power as well as an over boost code would be sticking vanes in the turbo. Does this sound right? If so, should I look at a rebuild or replacement of the turbo?

I donít have a scan tool btw.

Thanks in advance for any advice.

get an OBD2 wireless reader of ebay for $10 and download the torque app. on your smart phone. you can then set the screen to show a large boost gauge, which is very easy to monitor!

Any particular OBD2 scanner you know works on an iphone? Or are they all generic.

You can get a wifi one that will work on an iPhone just not the Bluetooth ones. How much more expensive the wifi ones are though, I'm not sure. Just punch in iPhone OBD2 adaptor into eBay and it should give you an idea.
