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 don’t have a scan tool btw.
Thanks in advance for any advice.
