59 Plate Outlander Overboost Fault :-(
 

Hi all, I have literally joined today and have owned my Mitsi for 6 months now.
So I bought it privately at 100k miles but, as is a deisel was not concerned. However, it has been losing power at high speeds and has thrown up the P0234 Overboost code.
I know there is a few things it could be (hopefully not a whole new turbo, crosses everything!)
I just wanted to hear what other people had looked at, what their process of elimination was and what fixed it for them in the end.
My local car guy will be doing the work as he also owns one and is a lot cheaper than taking it to Mitsubishi.
I will add that apart from this I literally adore this car, so really hoping I can get it sorted.
Thanks. :-)
